Firefox tab bar on mouse over

Since Firefox 57 I’m using Tab Center Redux for showing my tabs on the left side. Because of that (and since screen space is precious) I didn’t need the default tab bar and so I disabled it with the hack I found in the wiki of Tab Center Redux:

#tabbrowser-tabs {
visibility: collapse !important;

I found this solution quite useful over the last months, but recently I got some web design to do and split my screen horizontally in half. In this mode the width of the sidebar used to much space. Disabling it with F1 also didn’t really help because then I had no tab list at all.

Today I got the idea of only showing the default tab bar, when necessary. Since I can’t capture keys with CSS (and I didn’t find a way to create a user JS file like userChrome.css) and pressing a key to show and hide would be too much work, I got the idea of showing the tabbar when hovering.

The trick is to show a small rest of the tab bar above the address bar by default (in this case 5px). Only when the mouse cursor hovers this area, the full tab bar is shown. The following CSS code does this:

#TabsToolbar {
min-height: 5px !important;
max-height: 5px !important;
opacity: 0 !important;

#TabsToolbar:hover {
max-height: inherit !important;
opacity: 1 !important;

To use this, you have to paste this CSS code in your userChrome.css file.

How to run a web app on your desktop

Running a web app or a website on your desktop is nowadays much easier thanks to GitHub’s Electron.

Why would someone want this?

Well… This is a good question. For me there are only two reasons: you can start it from your launcher and it’s handled as its own application. But thats not why I’m writing this guide. My motvation is simple: It works.

A new design for

Today I roll out a first version of the new With this upload not everything is fully designed, but these missing pages will follow later this week or next week.

I decided to go in another direction using more subpages and the same design on every page, if it’s just a subpage or its own project.

While designing the new page I not only tried to create a beautiful theme but also to provide a smoother user experience through designing page change animations with JavaScript. What you can actually see is just the beginning 😀 . I’ll gonna improve the page animations to make them more seamless.
