Absolutely FANTASTIC

Can developer PLEASE EXPLAIN why this add-on required "Access your data for all websites" permission? That sounds like an EXTREME SECURITY RISK, for an unknown use or benefit.

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.

I'm going to have to troublshoot this for an extension conflict... FF 88.0b

The tabs ARE coloured nicely, but only appearing in the sidebar. I may keep it as is for I use a jazillion tabs and nothing seems to make them easy to differentiate

Great Extension!! :) It helps very much, to differentiate when developing in multi-level environments, like Local, Dev, Test, and PRO.

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