Firefox window began blinking different colors and became mostly nonresponsive. I could only get this to stop by removing the extension.

As others have noted, the description is misleading. I suspect that the author doesn't know what most people mean when they say "tab".

Also, the functionality, as near as I can gather, is useless. The whole window is colored according to the current tab, but other tabs have no distinguishing color. I think most people are looking for a way of enhancing information about the tabs, to easily choose the one you're seeking. This doesn't do that.

Absolutely false and misleading description. This add-on gives no control on individual tab. Totally useless

Like 49f7ab, I am looking for an addon that can permanently colour individual tabs (inactive or active, and nothing else) with custom colours - like colorful tabs used to but no longer does - like Tab ReTitle can rename tabs permanently.

Tree Tabs has customisable colours, borders and more for tabs by function, if you want that AnthonyH. The ability to permanently custom colour individual tabs is the only thing missing.

Could you do that dev?

This is not color tabs, just the current tab gets an aggressive color while the other tabs remain white.
If you want to return to the tab you made blue and you aren't currently on it, you have no idea where find it because they are all white.
This is useless.

Not so good, imo. I expected to see something that colors the *tabs*, not half the page. Please rename it properly or provide what the name says. Have a good one!

No control over which tabs get which color, not good for color coordinating types of tabs.
