Since updating Firefox today and setting my profile as the default (since the update required me to make a backup) I haven't been able to click tabs. I can make new tabs and open link in new tabs, but i cannot click from the main tab that opens when firefox opens to any other tabs, ctrl + 2 also doesn't work. I can't even open settings because it automatically opens it in a new tab.

It looks like they are loading correctly, since i can see the mini popup if I hover over the tab.
