Used this for years and always been great...until now. WTF happened?? Colours constantly flashing between colours. Needs a fix ASAP!!!!

I really like this extension and I've been using it for years. A lot changed because of how FF changed. I would love to see inactive tabs colored again but hey I still find it useful even without that! Thank you!

Highly appreciate the developers' effort. The concept is good and very useful. But it seems like a lot of preferences options are removed in current version compared to old ones.

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

Good idea but it didn't work properly.
It didn´t changed color of tabs. Addon created separated windows/sidebar with color 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.....

I like this. No matter the outcome i give 5 stars because the developer is keep trying to maintain the add-on.

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...

It definitely changes the colors of the tabs.... and everything else. Makes the browser look childish and annoying. Uninstalled.

My tabs did not change color as shown in the screenshot.

Only seems to randomly cycle through colors for each tab, never quite settling on any one color per tab.

It do not works.
After 5 years of usage it stops to work.

Firefox is determined to be the worst browser. Now Colorful Tabs doesn't work. Only the current tab is colored, the rest are white, which makes Colorful Tabs worthless!

it dont work in the garbage of firefox dev 88+... it will be nice if can fix the problem on this firefox..

This is great for the tabs on the sidebar, but the tabs across the top of the page are white except for the active tab. I receive a message about bugzilla, but cannot fix it.

It was my favorite extension for more than 10 years, so disappointed!!! Thanks to "par Blade, il y a 8 mois" for a replacement solution ++
