Some quick Vivaldi Javascript hacks to add additional functions

Warning: Do not apply this code to a current version of Vivaldi. It will not work anymore because the Vivaldi code has changed!


As follow-up to the previous entry about Hacking the CSS, this time we add some new functions to Vivaldi. The Idea is based on the posts you can find at (in Russian, Google translate helps if you don’t speak Russian). I changed them a bit to avoid some errors I saw in the debugging console and to make sure that they only do what they should (there were some minor glitches where unexpected things happened if you clicked in the wrong place – especially if you run the browser in UI debugging mode)

I ported 2 of the scripts:

“Click to minimize/hide the tab” which deactivates the current tab and shows the last active tab. (don’t click at the [x] – that still closes the tab ;))

“Right-click [+] button to paste and go in a new tab.


For testing reasons you can deactivate each of them by removing the first slash at the leading //*.

How to …?

Look in the application folder of Vivaldi for browser.html in the ressources/vivaldi folder and open it with a text editor.

Insert after the string and save it.

Create a folder in the same directory as browser.html and rename the folder to custom_ui . It should be already in the right place if you followed Method 2 in the previous entry about Hacking the CSS.

Save the following code as custom.js into the new folder:


(function () {     // get the whole browser UI. Do this only once!     var browser = document.body.querySelector('#browser');          // we need to emulate a click sometimes. Do this only once!     var dispatchMouseEvent = function (target, var_args) {         var e = document.createEvent("MouseEvents");         e.initEvent.apply(e,, 1));         target.dispatchEvent(e);     };      /*     Single click on a tab to hide it and show the last active tab.      */ //*     var list = [];     function listTabs() {         var tabs = browser.querySelectorAll('#tabs>.tab');         list = [];         for (var i = 0; i < tabs.length; i++) {             list.push(tabs[i]);         }         list.sort(function (a, b) {             return recent(b) - recent(a);         });     }          function recent(tab) {         var page = document.querySelector('.webpageview webview[tab_id="' + tab.dataset.tabId + '"]');         if (page) {             page = page.parentNode.parentNode.parentNode.parentNode;             return parseInt(;         }         return 0;     };      function startAction(e) {         for (var i = 0; i < e.path.length; i++) {             // clicking on tab group switches should not fire, neither should clicking anywhere in the webpageview             if (e.path[i].classList && (e.path[i].classList.contains('tab-indicator') || e.path[i].classList.contains('webpageview'))) {                 break;             }             if (e.path[i].classList && e.path[i].classList.contains('active')) {                 var active = browser.querySelector('');                 listTabs();                 dispatchMouseEvent(list[1], 'mousedown', true, true);                 break;             }         }     };          browser.addEventListener('mousedown', function (e) {         // Make sure that it fires on left mouse click only         //  e = e || window.event;         switch (e.which) {         case 1:             startAction(e);             break; // left         case 2:             break; // middle         case 3:             break; // right         }     }); //*/       /*     Right click on plus-button to paste and go      */ //*     var isItMouse = false; // Exclude responses from keyboard      //Tweak for paste in this input-field     var hiddenInput = document.createElement("input");     hiddenInput.type = "text";     browser.appendChild(hiddenInput); = "0px"; = "0px"; = "none";      browser.addEventListener('contextmenu', function (e) {         // Area near square         if ('newtab') > -1) {             isItMouse = true;             document.execCommand('paste');             return;         }         // Plus-symbol         // changed to parentElement instead of parentNode         if ('newtab') > -1) {             initPaste();             return;         }         // Square         if ('newtab') > -1) {             initPaste();             return;         }     });      function initPaste() {         isItMouse = true; = "block";         hiddenInput.focus();         document.execCommand('paste');     }      document.addEventListener('paste', function (e) {         if (isItMouse) {             isItMouse = false;             var url = e.clipboardData.getData('text/plain');

Some quick Vivaldi panels CSS hacks for better readability or accessibility

Deprecated. While the basic technique would still work, too much has changed in the new Versions of Vivaldi and now we have Themes.

While I generally like the design idea that stands behind behind Vivaldi, I have some problems with it. I don’t know which screens the designers use or if they are calibrated, if their eyesight is perfect or not, but the contrast of some elements in the default light and dark themes is a little bit too low for me to feel comfortable, especially in the panels. Luckily the whole UI of Vivaldi is based on web technology—or in non marketing speak: HTML, JavaScript and CSS—it is quite easy to hack.


Yes I resized the screenshot deliberately to a smaller size. As you can see everything in the panels stays visible, despite the smaller size . You can try that with the default interface, but don’t use sharpening while resizing 😉

The following hack does not solve all problems I see, e.g. the less than sufficient contrast of the Tab titles in the dark interface if you do not use transparent tabs, but you can see it as a first step for your own experiments.


How to …?

Method 1:

Look for common.css in the application folder of the browser and open it with a text editor.

Add the following to the end of it (make sure you add it at the end!)

Method 2:

Look in the application folder of Vivaldi for browser.html in the ressources/vivaldi folder and open it with a text editor.

Insert <link rel="stylesheet" href="custom_ui/panel.css" /> after the string <link rel="stylesheet" href="style/common.css" /> and save it.

Create a folder in the same directory as browser.html and rename the folder to custom_ui

Save the following code as panel.css into the new folder:

cleanPages readability update

Sadly it is broken again since the changes in the Chromium 64 engine.
I don’t know when or if I find the necessary spare time to fix it.

Since cleanPages finally broke with one of the latest Chromium updates because the OEX shim I use contained event creation code that is no longer supported I had to update it to get it working again.

You can download the fixed version 2.0.12 from my homepage:

You can install it in any Vivaldi version that allows dragging of CRX files to the vivaldi://extensions page.

You can reach the options from the extensions page or by pressing on the wrench icon of the cleaned page too.

Known Issue:

Vivaldi’s Spatial Navigation fails on the cleaned pages.

That is caused by the way cleanPages does the cleaning. It breaks on similar cleaning extensions too and there is nothing I can do against it because spatial navigation does not re-analyze pages that are changed by Javascript after the first full load.


PS: Does anyone still need a description of what it does? If yes I’ll write one.

PPS: I TOTALLY FORGOT to add any external libraries or tracking code 😀

Sadly it is broken again since the changes in the Chromium 64 engine.

“Du” vs “Sie” – oder: Wie förmlich darf’s denn sein?

Note for English speaking readers: It is about the differences in addressing people, formal or informal, in the German translation of and if we should use the formal (but not unfriendly) “Sie”, or the personal “Du”. I know, this is easy for you, because you can use “you” for both and I can understand that you think we are crazy (and that assumption is probably correct), but that’s how we are. If you want to know how it works here, take a look at this:

btw: I have been in the USA several times and while they use the you, you always know if it is used in a formal or non formal way. You will earn some looks of disapproval if you forget the Ma’am or the Sir in Huston,Tx or somewhere in the Bible Belt if you talk to a female who is not clearly a little girl or to a male person being older than you or carrying a weapon. No such problems in California – unless you are in a region with a high percentage of Mexicans. It is not that easy even in the USA, there are some lines you don’t want to cross. 😉


Es gibt Sachen, die meine Neugier anregen und denen ich auf den Grund gehen möchte, denn oftmals ist die wahrgenommene “Wirklichkeit” nicht gleich  dem, wie die Dinge tatsächlich sind. Diesmal geht es darum, wie “förmlich” wir Deutschen sind. Ausgelöst wurde es von einer hart (aber fair) geführten Diskussion, ob die Webseite die Besucher mit “Sie” oder mit “Du” ansprechen sollte.

Ich gebe zu, dass ich auf Grund meines Alters voreingenommen bin (meine jugendliche Prägung fand vor MTV und dem WWW statt), aber das Selbe gilt natürlich auch für jüngere Personen, die eigentlich keine Welt ohne WWW kennen und schon deutlich durch die wahrscheinlich aus dem englischsprachigen Raum übernommene “You” → “Du” Umgangsform beeinflusst sind.

Genug geschwafelt, ab zu den “Fakten”:

Wenn man wissen will, was die Leute in Deutschland so anstellen, befragt man am besten Google (Marktanteil bei den Suchen >90%, deshalb “optimieren” “alle” ihre Webseiten dafür – und Google ist ziemlich gut im analysieren) – also fleißig ab den Suchparametern geschraubt, mittels auf Seiten mit .de als TLD eingeschränkt und eine wörtlich zu nehmende Suche mittels &lit=1 eingestellt.

Hier die Ergebnisse, die ich bekommen habe: “Ungefähr 1.370.000.000 Ergebnisse” für “Sie”  “Ungefähr 246.000.000 Ergebnisse” für “Du”

Das sieht auf den ersten Blick nach einem klaren Sieg für “Sie” aus – aber ganz so einfach darf man es sich meiner Meinung nach nicht machen:

Zum einen wird “Sie/sie” auch für andere Sachen verwendet als nur die persönliche Anrede und zum anderen kann man mit ziemlicher Sicherheit vermuten, dass sich auf einem großen Teil der Seiten, wo “man” sich duzt (z.B. nahezu 100% aller Foren) oftmals Sätze befinden wie “Verfolgen Sie uns auf Twitbook”.

Um es mir etwas einfacher zu machen (Haben Sie ernsthaft erwartet, dass ich hier eine wasserdichte statistische Analyse anfertige? Nicht wirklich, oder? 😉 ) habe ich kurzerhand die “Du” Seiten von der Anzahl der “Sie” Seiten abgezogen – das macht aber immer noch eine abgerundete Milliarde Seiten, die die Wörter “Sie/sie” beinhalten. Folgend begebe ich mich vollständig in den Bereich der Spekulation und nehme an, dass auf 50% aller Seiten, auf denen “Sie” in irgendeiner Form verwendet wird, dies nicht aus Gründen der Anrede geschieht. Übrig bleiben immer noch eine halbe Millarde Seiten. Der “Sieg” ist knapper, aber immer noch deutlich.


Könnte das mit der Altersstruktur unseres Landes zusammenhängen? 

Für solche Statistikfragen gibt es einschlägig bekannte Seiten wie Statista 
Wer will, kann sich gerne dort durchwühlen und nachrechnen. Ich bin faul und lasse das lieber andere machen, also habe ich einfach bei Wolframalpha gefragt, wie alt wir Deutschen im Schnitt sind:
Für mich erklären 43,8 Jahre einiges:

Ein großer Teil der Bevölkerung erlebte seine “prägenden Jahre” bzw. fast die Hälfte seiner Gesamtlebenszeit vor der verbreiteten Einführung des persönlichen Computers, vor MTv, vor dem WWW und vor dem “Handy™”. Damals wurde man vom größten Teil der Bevölkerung tatsächlich gesiezt (sogar unsere Lehrer haben uns ab der 5 Klasse auf dem Gymnasium gesiezt – und wir sie natürlich auch) so lange man sich nicht gut kannte oder wirklich befreundet war (nicht nur auf einen noch nicht existierenden “Freund” Button geklickt hatte). Die Flower Power Generation war zwar schon vorbei und dadurch hatten sich glücklicherweise schon einige Umgangsformen gelockert, aber dennoch hielten die meisten hartnäckig am “Sie” fest – und das waren nicht nur die Ewiggestrigen: Selbst die ’68er redeten Leute, die sie nicht kannten, mit “Sie” an, außer sie wollten gezielt “Das Establishment” provozieren.

Solche Verhaltensweisen legt man nur relativ langsam ab, ich spreche da aus Erfahrung.


Zurück zum Anfang:

Sollte man auf der Seite “Sie” oder “Du” verwenden?

Für mich persönlich keine Frage. Seiten von Firmen, die nicht gerade Betreiber von sozialen Netzwerken sind, sprechen ihre Kunden im Allgemeinen mit “Sie” an (OK, IKEA nicht – außer es kommt eine Durchsage:  „Gesucht wird der Halter des Fahrzeugs mit dem Kennzeichen DU – DA 496. Bitte melden Sie sich umgehend an der Information!“ 😀 ). Das ist zwar formal, muss aber dennoch nicht distanziert sein. Der Grat zwischen anbieten und anbiedern, zwischen persönlich ansprechen und zu kumpelhaft – und somit meiner Meinung nach eher unprofessionell – ist ein sehr, sehr schmaler. Die Gefahr, auf den Empfindlichkeiten der unbekannten Personen herumzutrampeln, die die Website besuchen, ist beim “Du” meiner Meinung nach größer als beim “Sie” – aber das ist nicht wirklich messbar, nur von jedem einzelnen fühlbar, dennoch vermute ich einen Grund hinter der Verwendung des “Sie” auf folgenden Seiten:


Für die Seite (also die mit den Foren und Blogs) ist natürlich das “Du” völlig OK.


Ein wenig Literatur zum Thema:


Letztendlich stellen sich folgende Fragen:

  • Würde ich einen Fremden, über den ich nichts weiß, außer dass er mein Produkt verwendet, am Telefon mit “Du” anreden?
  • Verärgert es eine unbekannte “Du” Person mehr wenn man sie mit “Sie” anspricht, als eine “Sie” Person, die man mit “Du” anspricht?
  • Ist der Kunde nicht der König, sondern das Produkt? (Facebook)
  • Will man ernst genommen werden?
  • Ist man in der Lage eine vollständige Image Kampagne mit einer weitergehenden Botschaft und einer gezielten kleinen Provokation durchzuziehen? (IKEA, Lebensstil)

Kann man alle Fragen mit “Ja” beantworten, ist das “Du” kein Problem – sobald man eine Frage mit Nein beantwortet, sollte man sich meiner Meinung nach wirklich überlegen ob man bereit ist, diese Grenze zu überschreiten.


… und nun möge die Schlacht um das “Du” und das “Sie” in den Kommentaren beginnen 😀


Sometimes You Might Not Need jQuery

While I was idly surfing through the web I stumbled over an older blog post from 2011 that featured Earthquakelet, a bookmarklet that lets you experience the funny side of an earthquake by shaking the contents of the window. (Disclaimer: Real earthquakes are no fun!)

While I am sure that the author can do much better when writing code (In fact he proved that he can often enough) this time he simply hacked things together for the laughs. So, nothing against the author—it is totally OK to do as he did—but it is a nice example that, depending on your audience, you might not need jQuery to get things done. The code might be shorter and often faster even if you use the famous vanillaJS library …


The following example is provided only to show that this is no false claim and because it is so nice and short.


Earthqualelet, a bookmarklet found on this page

917 bytes (635 minified) of code plus additional 72357 bytes download of jQuery

(function(w,url,hasjq) {
     if (!(hasjq = w.jQuery)) {
         var s = document.createElement('script');
         s.src = url;
         (document.getElementsByTagName('head')[0] ||
     }     (function go() {         if (!w.jQuery) {
             return w.setTimeout(go, 200);
         }         var $ = w.jQuery;
         if (!hasjq) $ = $.noConflict();
         var $s = $('p,div,img,span,strong,em');
         (function shake() {
             $s.each(function() {
                 if (this.shift) this.shift = 0;
                 else this.shift = (2*(Math.floor(Math.random() * 2)) - 1) * (Math.floor(Math.random() * 4));
                 $(this).css('margin-left', this.shift);             });
             w.setTimeout(shake, 80);
 })(window, '');


The “minified” bookmarklet:

javascript:(function(w,url,hasjq){if (!(hasjq=w.jQuery)){var s=document.createElement('script');s.src=url;(document.getElementsByTagName('head')[0]||document.getElementsByTagName('body')[0]).appendChild(s);} (function go(){if (!w.jQuery){return w.setTimeout(go, 200);}var $=w.jQuery;if(!hasjq)$=$.noConflict();var $s=$('p,div,img,span,strong,em');(function shake(){$s.each(function(){if(this.shift)this.shift=0;else this.shift=(2*(Math.floor(Math.random()*2))-1)*(Math.floor(Math.random()*4));$(this).css('margin-left',this.shift);});w.setTimeout(shake, 80);})();})();})(window,'');



Hand coded Earthquakelet, no jQuery

400 bytes (223 minified)

(function (w) {
     var ele = document.querySelectorAll('p,div,img,span,strong,em'),
         len = ele.length,
         i = 0,
         shift = 0,
         M = Math;
     (function quake() {
         for (i = 0; i < len; i++) {
             shift = M.floor(M.random() * 6) - 3;
             ele[i].style.marginLeft = shift+'px';
         };         w.setTimeout(quake, 80);


The “minified” bookmarklet:

javascript:(function(w){var e=document.querySelectorAll('p,div,img,span,strong,em'),l=e.length,i=0,s=0,M=Math;(function q(){for(i=0;i<l;i++){s=M.floor(M.random()*6)-3;e[i].style.marginLeft=s+'px';};w.setTimeout(q, 80);})();})(window);


As you can see, the hand coded bookmark is even shorter than the bookmarklet using jQuery. It works in every modern browser that supports bookmarklets and in older browsers that support querySelectorAll. So if you don’t need to support IE7 or older, you should be quite safe to go.

Beware of the


Yes, it is an SVG image 😀


It seems that Firefox and Internet Explorer have a problem with raw SVG code as image source. I had to URL encode it (base64 would have worked too, but it is about 30% bigger and gzips worse).

Dear Mozilla and Microsoft programmers:

It is legit and standard conform to use the raw stuff. “The Real Opera(TM)” (aka <14) can do that since version 7 (or may be even earlier), Chrome since about version 7 (that is several years later than Opera 7), and Vivaldi since the beginning too. Fix it!

PO2JSON converter for Vivaldi translation purposes

Outdated. Use André’s online converter instead.

You can find it here:

Translating Vivaldi was always a bit difficult when it came to string lengths or if we needed to see exactly where the string is and if it is the right one in that place. Luckily An_dz invested some time to write a nice little JavaScript for the dev console that can convert files from the POEDIT format used for translation to the JSON format used in Vivaldi, which works well …

… but I am a lazy guy and did not want to copy the file to the console each time I needed to test new translations, so I modified some (few) lines in his script, added some file read/write stuff and stuffed it into a simple webpage. When run locally, it allows to load the .po file,  convert and save it as messages.json file. This file can be used with Vivaldi to test the translations.


Alternatively you can use ludev‘s online converter which is based on this script. It can either download the PO file directly from Transifex, convert it for you and store it to your computer for further use – or you can use your local PO file for the conversion.

The online converter is availlable at

  • Save the code as VivaldiPO2JSON.html to your computer somewhere where you can find it again
  • Open it in Vivaldi
  • Choose the right PO file
  • Convert it
  • Save the converted file

All mistakes are mine An_dz code works just fine. Feel free to post improvements below 🙂


edit: Thanks to An_dz for the changes! (See his comment below) 🙂

EXIF Viewer Extension for Chromium Based Browsers

As an old (and long time too 😀 ) Opera user I really miss the handy images properties display in the new Chromium based browsers, especially the EXIF info, so in pure self defense I decided to modify some code taken from  and added some context menu magic to it to get a similar function in Opera 15++ and Chromium 9++


Additionally I added a small parsing routine for raw GIF file data that shows the number of frames in animated GIFs (Thanks to Brian for the head up which bytes probably start a new frame – you were right). Sadly It doesn’t seem to run on a Mac (as one user reported) and I can’t do anything against it because I don’t own a Mac (Windoz rulez! 😀 ) and I didn’t do any tests on Linux so far – anyone? Works in Mint.

Here the links to the extensions on my private web-space:




 Test image. Right click on the spider

edit 2014-05-17

If you want something fancier, you can try this extension from the Chrome store (Thanks to Alexs for the hint) I didn’t test it yet, so I don’t know if it shows e.g. the number of animation frames in a GIF too – if yes I will at least have learned a little bit by cobbling it together by myself.

edit 2014-05-20

A really nice implementation with the benefit of adding some of the old Opera right-click on an image behavior too can be found in the Opera add-ons catalog (Thanks to claudio791 for the hint). It displays the EXIF metadata too and the source code is available at GitHub. (Nicer code too because Joel is a real programmer)


Why another EXIF viewer?

Simply because I wanted to have one that ends its process and unloads itself from the memory when it is not needed and that does not inject anything to the page with the image …

(If that is of no concern for you, you might give one of the many other image and EXIF related extensions a spin, especially this one is very nice.)


… and of course because I wanted to see if I can do it.



edit 2014-05-18

Updated the Extensions from background page usage to event page usage and reduced the permission set. Urgh – geek language alert!

OK, in plain text: It now unloads itself if it is not in use, meaning, it will free your RAM etc. and I set only the permissions for the extension that it really needs for work. Now it can’t access all of your history, all of your tabs etc. any more – only the tab in which you right click on an image. IMHO more extension authors should do that, but most of them do not give a s**t about that and grab everything they can. I am not so sure if that doesn’t have security and privacy implications …


edit 2014-05-19

Version 1.0.7

  • Removed IE compatibility stuff from the binary AJAX module.
  • Corrected the MIME-type display to the value the server presents.
  • Removed needless use of canvas for the “thumbnail”.
  • Added some more EXIF values.


edit 2014-05-20

Version 1.0.8

GPS, yay! You can test it with this image on flicker

Warning – 6 MBytes image, the extension might take some time to download the raw binary data (e.g. 10s with a 6 Mbit/s connection)


edit 2014-05-21

Version 1.0.9

Rudimentary IPTC support added. You can test it with this image.


edit 2014-05-21 / 02

Version 1.1.0

IPTC mapping complete as far as it made sense for images.


edit 2014-05-23

Version 1.2.0

Added display of XMP metadata.


edit 2014-05-23 / 02

Version 1.2.1

Syntax highlighting of XMP data added, should make reading a bit easier.


edit 2014-05-23 / 03

Version 1.2.2

Link to the place in Google and Bing maps if GPS coordinates are present (opens in a new tab).

Hint: if you use this image, make sure you switch to street view too 😀


edit 2014-05-24

Version 1.2.3 (for internal tests with search engines onyl)

Version 1.2.4

Added tabbed interface

Added Maps and OpenStreetMap



edit 2015-04-22

Version 1.2.5 (for internal tests with onyl)

Version 1.2.6

Works in Vivaldi

To install:

  • download the file and unzip it with 7zip or a similar unzipper
  • open the page vivaldi://extensions
  • switch to developer mode
  • open unpacked extension and navigate to the folder where unpacked the extension (the folder that contains the manifest.json file)
  • drag and drop the CRX file on the extensions page
  • confirm the installation and activate it

Open a webpage with an image or one of the above linked test images, rightcklick on it and select the Extensions entry in the context menu



Please keep in mind that I am not a good Javascripter, more of an advanced copy&paster, and I am quite proud that I was able to parse the binary data at all, so please don’t shoot me if something goes horribly wrong. Feel free to post improvements or wishes in the comments below 🙂


CSS beautifier

I confess that am a messy coder when it comes to formatting. I edit, insert and delete until the code runs like I want to. This often leads to perfectly readable code – for machines, but not for other humans – so if I decide to publish it, I shouldn’t publish it in the same form I write it.


When I was editing my userCSS for vivaldi once again, I messed up the well formatted code the same way as usual. Of course I could have used an editor that formats on the fly, but I don’t like editors that change the formatting while I am coding, all that moving around makes me dizzy. While I was looking for a solution for that problem I found this:


CSS Beautifier –


Simple to use, you can even download it to run it offline in your browser, with a few clicks the code looks just fine and you can change the way it is formatted in a blink. Exactly the simple thing I wanted 😀


Helps with the usual one-line-we-save-every-bit code that is presented in some webpages too (Google, I am looking at you!)
