Best add-on ever. It's so essential.

Read Bug 1320585 on Bugzilla. OMG, why don't they implement tab colouring??? They even locked comments on that bug after they saw that so many people would love to have tab colours. Why do they hate users so much?

It's nice to have at least that current workaround with ColorfulTabs. I needed the original XUL addon so much, that I actually extended it to have C&P functionality.

IMO, tab colour should not be left to addon developers, but should be a HTML meta property like: . It belongs to the same place as favicons. It's weird that you can set a favicon in HTML, but not a background to it. The first one is totally normal – the second a sacrilege? This way it would be as easy as CSS to overide the tab colour with a user or extension set colour.

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 💔

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
