User Reviews
Pros
- Tab coloring is the core appealing feature and concept.
- When it worked, it offered colorized tabs across multi-window setups (multi-row views).
- Some users praised the add-on as fantastic.
Cons
- Often not working or becomes non-functional after updates.
- Forces a light theme and bright appearance, breaking dark themes and reducing readability.
- Alters the browser toolbar/URL bar color, causing visual disruption.
- Requests broad 'Access your data for all websites' permission, raising security concerns.
- Incompatibilities with other extensions (e.g., TreeStyle Tabs) and UI not matching screenshots.

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: <meta name="tab-color" value="{any CSS color}">. 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.

Is ColorfulTabs Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
ColorfulTabs requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
