Too bad it can no longer color all of the tabs but still a nice add-on.

Worked well until I "upgraded" to FF 65 - now just shows one color across all tabs.

This addon used to be first class, It used to color all tabs now it only colors one at a time. The screen shot shows it as it is supposed to work but it is not. Please fix this or it is worthless.

These are lovely - a must have for keeping tabs in order.

The tabs are ALL WHITE. 'Colorful' MY ASS.

Thanks!
But can you do a version compatible with TST (Tree Style Tab)? :)
Because it broke identation of tabs... :(

Es überfällt einen direkt. Viel zu viel und aufgeblasen. Ich habe keine Zeit mich stundenlang mit einem Add-on zu beschäftigen, um es passend zu machen. Wer´s mag ok, nix für mich.

keeps long hours working from getting boring, also helps with the eyestrain, great app.

It doesn´t work! The tabs are always white!
