Rated 3 out of 5 stars

Windows 7 - FF 55.0.1 (64-bit) - Colorful Tabs quit working. When I went to the versions page, I had to roll all the way back to 31.0.9 to get it working again. 31.0.9 installed, Automatic Update disabled.

This review is for a previous version of the add-on (31.1.9).  This user has a previous review of this add-on.
