Without Tab Utilities Firefox is just some browser. Rated 5 out of 5 stars

Whoa, Bug 776290 has been marked as "RESOLVED WONTFIX" what a way to ruin not just this essential add-on but several others as well. I thought Mozilla was working on a way to fix add-on compatibility and not make add-ons obsolete

Firefox may have great add-ons but without an efficient way to handle tabs... Mozilla, you have pushed me, a loyal Mozilla fan, 85% closer to a browser I never thought about using, Google Chrome.

I really hope to see Tab Utilities rise again.

This review is for a previous version of the add-on (1.2).  This user has other reviews of this add-on.
