Tabs at bottom

Firefox tab bar at bottom of window.

Firefox userChrome JS script.

Tested on firefox 140.

Difference from other CSS code:

• Also uses JS to manipulate DOM
• Handle fullscreen status by JS MutationObserve

Notice: do not load this code by tab bar itself, or firefox will infinite loop.

This repo only contains the specific function, doesn't contain the code to enable userchrome scripts.
