Minimalist (not working currently)

Minimalistic Firefox Theme using userChrome.css.

Save space and only focus on the neccessery things.
The current Tab title and its favicon are fully displayed alongside the URL bar. Other tabs only get displayed on hover.

Tab size increases on hover for better visibility.

Compatibility

Update: Even though Firefox added backdrop support by default the blur in this theme doesnt work perfectly.

Attention

Forwards and backwards buttons are removed in this skin, it's meant to be used with keyboard or mouse shortcuts
(maybe a button version coming in the future)

If you firstly install the theme it might look not as expected, so you have to adjust your Firefox Symbol bar

Installation

1. In about:config change those values to true:

toolkit.legacyUserProfileCustomizations.stylesheets --> (basic support for css)
gfx.webrender.all --> (support for background blur features in the top bar)
layout.css.backdrop-filter.enabled Not necessary Firefox v 103 and above

2. Type in about:support and find the path of your Firefox Profile Directory.
3. In there, if it doesn't already exist, create a folder called chrome. Paste the .css file without changing its name
4. Restart Firefox and enjoy your new theme!
