Rated 5 out of 5 stars

Works flawlessly in FF 4! Also, @Khun, you don`t HAVE to pay. The option`s there for if you like the add-on and want to contribute to its development.

This review is for a previous version of the add-on (4.1.0). 

Rated 5 out of 5 stars

I got my button back a LONG time ago now, and it works perfectly! As for the Add-on itself... It`s brilliant! Nothing else I can say about it.

This review is for a previous version of the add-on (4.0). 

Workaround Rated 4 out of 5 stars

I Can still show it by pressing the Alt key, but it would be nice to have my button back.

This review is for a previous version of the add-on (3.1.1).

Could any of these be the problem?

This review is for a previous version of the add-on (3.1.1). 

Compact menu, Please come back! Rated 3 out of 5 stars

Was fine before, Now its GONE!
Now Ive got NO menu whatsoever!
Please help!

This review is for a previous version of the add-on (3.1.1). 

Perhaps conflict with other Add-ons

Open add-on window (reinstall Compact Menu 2 from web), disable other add-ons and reboot firefox.
Please tell me conflicted add-on.

Rated 5 out of 5 stars

I didn`t want to completely hide the menubar, This is just what I wanted!
