Rated 5 out of 5 stars

I like this add-on and have had it on my laptop for at least a year. Last month I got an Acer One Aspire with Linus Linux, and added Ubuntu 9.10 Netbook Remix as a 2nd OS. Firefox generally works fine, but some add-ons clash with the "Ubuntu Firefox modifications" add-on. In fact it prevents you adding icons to the Navigation Toolbar which negates using Compact Menu. I will report this to Ubuntu, but in the mean time if you are using Ubuntu and want Compact Menu 2, then disable Ubuntu Firefox mods.

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