Fixed isssue Rated 5 out of 5 stars
The issue was with conflicting extensions. After I disabled them, Compact Menu 2 worked flawlessly.
Excellent Rated 5 out of 5 stars
I've been using your extension in FX and TB since it was first published. It really makes the UI much cleaner. I've just downloaded TB 10b5 and noticed that Compact Menu 2 doesn't install on the compose window and when I try to customize the compose window and drag Compact Menu 2 to the window, there's nothing to drag. I don't know if there may be a conflict with another extension or if there's an issue w/ this version of TB. I figured I'd tell you about it nonetheless.
Great Add-on Rated 5 out of 5 stars
I've been using this since its first appearance; when a new beta release of Firefox came out and this extension wasn't updated for it yet, I bumped the .rdf so I could enable the functionality. While the FF button now kind of obsoletes this extension, I still use it because of its aesthetics.

Went to your github site and downloaded 3.1.1. Upon installation, received error message 207: Not a valid install package. Not going to dis your addon because of that, though. I've been using it a long time and it just works. By the way, tried to download it from Mozilla, too, and received 208 error, too.
