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

Terrible addon. It changed the colour of the main toolbar/URL bar area too, making everything painfully white and impossible to read. I had to restart the broweser after uninstalling ColorfulTabs to restore the theme. It also broke TreeStyle Tabs, making it impossible to change tabs or even close them. Garbage addon.

How can such a lovely idea turn into a fiasco crap show such as this?

As soon as I gave permission for the add-on to work it completely overrode my dark theme utterly and entirely.

Sure, everything than looked as if I had been slipped some acid and then tossed into a bag of skittles...all pretty pretty like. But, then going from all blacks, grays, and whites to an acid trip from hell was worse! I couldn't differentiate one thing from another as everything had been turned into Skittles!

Everywhere I looked, there were Skittles...

There were Skittles there,

And Skittles there...

Here a Skittle!

There a Skittle,

Everywhere a Skittle Skittle!!!!

After putting my eyes back into my head, I had no other choice but to dump the bag just to get my calm, relaxing, and boring Dark Mode back.

So a warning to you all, if you're easily triggered by sudden flashing colors, random flashing lights, or just the random sight of a handful of Skittles coming at you... move on. Save yourself.

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.

Literally useless ! Doesn't even have an configurable options !!!! Don't waste your time !

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...
