ColorfulTabs is a wonderful extension, but I'm on Firefox Quantum 65.0.2 (64-bit) and I'm still only seeing one of my tabs colored. This is disappointing; the screenshot should be replaced with one that shows the tabs as they actually appear, not as they used to appear.

Работает не так, как заявлено. Цвет имеет только текущая вкладка, остальные вкладки без цвета. Скриншот давно уже пора обновить в соответствии с актуальной версией FF

I have used ColorfulTabs for a long time. I cannot imagine being without them. Thank you.

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.
