I just installed Firefox 22 via PPA, and during installation I noticed the global menu bar integration add-on version 22 also was included, but when I launch Firefox I cannot locate the add-on to disable it. In version 21 it was there, and I did disable it because I do not like to have the menus in the menu bar, but rather have the Firefox button next to the tabs.
I did search for an answer, but didn't find anything most likely because version 22 just came out. I removed the add-on via terminal's purge command, and it completed successfully, but after reboot the menu's are still in the menu bar. I also completely removed Firefox via Synaptic, installed the Software Center version, and was able to disable the add-on as before, so I re-downloaded 22, but again it's not found.
I then looked for the add-on to see if it was installed, and it was, but it's not visible within the add-on themselves. I noticed on the global menu bar integration PPA page it states as of version 22 is no longer supported, so I'm confused. How do either remove this add-on to get the Firefox button back by the tabs, or make it so I can disable it in the add-on's page within Firefox?
