Great extension and idea.
Unfortunately, last update broke it for me and deleted all site lists (i.e. customisations), hence why not five stars. I'm not going to spend hours after every update just to recreate a experience which then just becomes lost.

Super simple and works very well. Genius idea and excellently executed.

Very good add! works perfectly

If only Windows 11 could syncronise too! Honestly this is brilliant.

this trash Adaptive Tab Bar Colour by Eason ruin my css, and after uninstall this my firefox still flickering

非常好用且美观的插件，要是手机版的firefox也能兼容就好了！！！！
