It was useless 3 years ago, and it's useless today !

All the tabs remain the same colour UNLESS you click on one of them !!!!!!!

The Extension SHOULD colour all tabs at the top of the screen a different colour, because by default they are all white. But it doesn't.

I have not been able to get more than 1 tab colored and that one is the open tab. I would love to have my tab colors back

Not working, no trace of any way to select a colour for any tab, I uninstalled it

RIP 💔

It used to work now I cant get it to work. It used to work was a great addon when you have many open windows in multi-row especially although for that you have to use Floorp Firefox based browser.

Extension not looks like on screenshot - it change background of whole browser and does not change color of inactive tabs

Horrible now, turns my dark theme bright white.

Forces light theme

Ne prends pas en compte un thème sombre. Efface sans retour possible les réglages de thème sombre qui étaient définis. Ne prévient pas bien de ces modifications.

Changes my settings without a permission.

1 start just for the description alone.

- Opens a tab to a random website after installation
- Does not color inactive tabs.

after update FF from... 3.6 this addon was very helpful, but now, its useless. and when i use dark skin, its totally failed. solors....omg my eyes feel sharp pain! and most of all. colors per tab changes only whel i click on it!!!!!! but im need to change color before i open tab! to separate per one in many opened ( now its impossible ( very sad.....

This extension no longer works like it used to. Used to be my favorite. Really disappointing.

What happened to the "old" Colorful Tabs, like your screenshot shows? This current version is completely useless! I removed it and will look for something else.

Totally useless.
Changes colors without prompting for agreement.
Changes all colors.
Changes colors all the time, whenever one navigates.

Very counter-productive...
