I always used this add-on and wished it looked like the screen shot. I don't like the color bar all the way across the screen I preferred just the tab the new approach is too distracting. I had customized colors for my commonly used sites but it doesn't appear that the new version allows this. Random colors are not helpful. Also when only the selected tab is colorized and have to read the tabs rather than just selecting a color. Hopefully it will improve but for now bye, bye

Just terrible

Non funziona. Non e un problema FF57. Altri addon funzionano. Basta! Finito.

There should be a special zero star for this one.

I have it disabled because Firefox Themes stops working when Colorful Tabs is turned on. I check periodically. Today 12/20/2017 it is still happening. Using Firefox 57 and 58 beta (on two PC's).

It is not final

I was looking for something to replace TabMixPlus' ability to highlight tabs which have been "unread". This extension is not it! It kills off my theme, replacing it with garish white background (for menu bar and tab-bar) and neon candy-store colors for the active tab and bookmark bar. NO THANKS.

Once and if it is fixed I will give 5 stars, sure. I am not going to give 5 stars to "encourage and support" the developers to do this, one day, maybe. Sorry, no, that's not how it works.

This is junk until fixed and it should have either been fixed over to the webextensions standard during the more than 1 year Mozilla gave or it should have continued to stay disabled as a legacy add-on until it was ready. Rolling out a broken update and expecting anything other than 1 star is whack.

I blame FF not the Colorful Tabs developer. Other favorites don't work as before either.

What's a good substitute for FF (which I've had for many years)? Safari? Microsoft Edge? Chrome? What???????

Registered to give my 1 vote since it has gone berzerk with colours awash

Removed after 3 years. Better without after 57.

Shame. This was good once. Bye!

So broken, it is not even meaningful to review something that fundamentally does not do the basic thing it claims.

It used to be better, now it changes the color of not only the tabs, but the entire theme. This is not acceptable and not beautiful. It would be better to remake it.

Das ist ja fürchterlich.

Add-on looks like a bad trip.

Mais comment désactiver ce fond insupportable et envahissant dans la dernière version??? Quelle idée de programmeur tordu a conduit à nous fatiguer les yeux à ce point!!! Merci de séparer l'onglet du reste, une simple;cas à cocher devrait suffire! Ecoutez les critiques, et bougez-vous! En attendant, je suspends cet add-on.

C'est nul!

Used to be my go to extension after any upgrade, but now, it is worthless. It is not at all compatible and will be uninstalled immediately.

No. Just no.

Up graded junk, WHY??

it's a garbage. DO NOT INSTALL
