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!

I love it but can't get it to work on Firefox, so I changed to Waterfox, would like to get it work again without re-installing Firefox.
How do I get into firefox to program "%appdata%\Mozilla\Firefox\Profile.*******\Chrome\userChrome.css"

Did not work for my version of Firefox (62.0.3). Instead of colouring the tabs .. this addon left them white and only changed the browser colour for each tab I went to when I went to them.

2 stars because it is compatible with 62.0.3. But it doesn not work as the picture shows....it only colors the active tab AND the menubar, URL bar... and all the other tabs look like they used to before this add-on was installed.

Can't deactivate the terrible sidebar "feature", so I am done with ColorfulTabs.

не работают цвета вкладок,все вкладки одного цвета

waw

Are you serious? We have to enter the hex number of the color? How the hell are we supposed to know that you need to have a GUI interface with a slider so we can just pick the color of and the Hue by looking at it not by studying a chart of numerals. LOL. This is like going back to the Heyday of dos programming
