Good in concept. I ran into issues, probably caused by conflicts with "Firefox Color" or the new vertical tabs setting. When I tried to use this it only changed the colour of the active tab. When I disabled the extension it removed all styling - resetting to base. I needed to toggle the 'Firefox Color' extension to get back to theme before using this extension.

Doesn't work, doesn't color the tabs. Firefox 113.0.2

It would be great if it worked. I tried different themes to get it to work, since looking at the code that's what they were trying to do, but it didn't make a difference. I'm keeping it installed in hopes that future updates will actually work since I'd love to have it for all the tabs I have pinned.

Very simple and easy to use! I multi-task a lot which means I have a lot of tabs open at once - having the active tab be coloured makes it so easy to not get lost in what I'm doing. Before downloading it I'd accidentally close my active tab a lot, so this is a god-send.

A small suggestion would be to have the option to change colours based on hex code instead of RGB/HSL, or to have an eyedrop tool to pick a colour from the screen - I like the colours of my tabs to match the logos of the sites they're from, and an addition like that would do wonders. I think, if possible, having the option to pick the colour of the text in a tab would be a great addition too.

One small thing that's more in the way of a correction/fix is that switching from a coloured tab to an uncoloured tab makes the uncoloured tab's colour flash for a moment. EDIT: another thing, sometimes uncoloured tabs spontaneously take on the colour of the previously selected tab and remain that way until you switch to a different tab

Keep it up, I love it!

Does not work.
