hi, FF doesn't seem to be compatible with windows 8.(1) x64, from 31 on. i installed v31, 32, 33 and 34 and none of those had a working "open menu". i search allover the net, and did not find a solution. i deleted all that i could 10 times to no avail. i am using version 30 and the button works i am very sorry not being able to use the latest FF version, i think its the best project and the only privacy respecting option in the browser world. thanks
