Rated 5 out of 5 stars

colorful tabs works perfectly on this setup; linux and firefox 19.0.2.

colorfultabs is unobtrusive; it doesnt colour in half of the skin like some do.
the addon also makes it so much easier to follow multiple tabs using the perfect colour shades.

colorful tabs has become a favourite of mine already,its liquid gold in comparison to the other colured tabs addon that have just had to remove; the developer has started adding adware to it-disgusting misuse of the people who support their work.

This review is for a previous version of the add-on (17.6).
