Works great except... Rated 4 out of 5 stars
It works really great, EXCEPT when I have a lot of tabs open and click on a different tab, and I end up on a tab no where near the one I clicked on. I can't tell what situation is causing this. I turned off Colorful Tabs, and Firefox works as it should when going to a different tab, so it is something in the Colorful Tabs that seems to get confused.
