Rated 5 out of 5 stars

As announced before, I downgraded to v19.9. Now I got the old color picker UI back and the tab stack (thick line below the tabs) doesn't break the tab scroll function anymore. :-)))

Yeah! ColorfulTabs 19.9 gets *** 7 Stars ***! Hopefully, the author fixes the future versions and I can update again.

p.s.: I installed "ColorfulTabs fixes" stylish script -- and it's a lot of fun. Although now, I don't need it any longer to fix anything. But you can make fun stuff with the tab texts' style to make the ColorfulTabs experience even better. :-)

This review is for a previous version of the add-on (21.3.1-signed). 

Rated 5 out of 5 stars

This is a thing I can't use Firefox without it. You just can't describe how much more difficult it is to use plenty of tabs without this addon. But unfortunately there are several annoyances and bugs ...and it's getting *worse*!

At first, you have to disable the tab stack (thick colored line beneath the tabs) in the current versions, since it breaks the correct function of the tabs. The tabs always scroll to the far left and the current tab (if seated to much at the right) will get out of sight, whenever window looses focus. So you have to scroll right, ... and scroll right again, ... and scroll right again, ... and scroll right again, ... and ... and ... and ... :-(

Next, the whole thing could be more handy: I very often want to set the color of a lot of tabs manually, which always needs a lot of tedious clicking to be done. I really wished one could do this faster and even (if possible at all) could kinda "copy" the color of one tab to another.

And currently this got even *worse*, since the new color picking UI is *broken*: It won't let you paste or type a color textually (although it says so explicitely). There is a text field with a cursor and a caption that says: "type in the color value", but no matter how hard you hit the keyboard, no character will ever reach the field.

Another weakness: There have always been to few colors to pick. Would be wonderful, if there was a rich color picker to pick millions of colors or even save you own colors in a user palette or sort of for future use. And there should be three parallel fields to type in and show the color value as RGB decimal, RGB hex. as well as as HSL.

But these are dreams. It would be pretty enough, if only the bugs were killed. I try to install the stylish script that allegedly will fix some of the addon's problems (see the other reviews for this) and maybe also try to change to an earlier version for now. Hopefully, I find one compatible with my Firefox that has fewer problems than the current version.

But nevertheless, if you wonder, why I gave it five stars. It's because this addon is so useful and indispensable and absolutely necessary that even the most basic features and even with some buggy annoyances it's still (almost) five stars. I would say 4.6 stars, which rounds up to 5, obviously. :-)
