firefox-hide-tabs

A CSS override that pairs well with the Tree Style Tab extension (which enables managing tabs in a side panel). It is basically an enhanced title bar for Firefox.

It removes tabs from the toolbar but keeps the current tab's title and favicon, as well as the "List all tabs" button, which can be used to manage tabs until you feel the need to open the side panel.

It has been tested with (Ubuntu 22):

• Firefox 105 (v1.0)
• Firefox 106 (v2.0)
• Firefox 108 (v3.0)

I may continue to maintain it.

How to use

1. Navigate to about:config and set toolkit.legacyUserProfileCustomizations.stylesheets to true;

2. Navigate to about:support and locate your Profile Directory;

3. Create a chrome directory there if does not already exist, and place hide-tabs.css and userChrome.css in that directory;

4. Restart Firefox.
