It works great, this kind of customisation is what makes Firefox better than others. But the pop-up preview prevents me from seeing my saved themes, it's annoying.

hate it have lost hours trying to loose t.

Just wanted my blk/wht scheme back. Accidentally lost it so this was cool. Maybe I'll play with colors more, I dunno.

Gotta love this add-on. I always make FF match my current Windows theme, something unable to achieve in other browsers. Mmm consistency.

I've love this addon. There are some weird issues since the Firefox 89 update though.

The standard "System theme" is supposed to "Follow the operating system setting for buttons, menus, and windows" yet in Firefox 89 it no longer does so. This extension lets me at least manually set Firefox colours to match the OS theme, and visually differentiate between active and inactive Firefox windows.

Useful but the display "pop up" window covers the saved themes tab and prevents you from selecting previously saved themes.

Not 5 stars because it needs improvement, further development, and repair. Setting (Background Tab Text Color) to black changes the colors of the Back-button (I have disabled Proton theme). I had to use a CSS-code to get the Back-button to display the colors I want.

Can't get to page to change anything so at this point, totally useless.
