I had to uninstall Firefox. I briefly added then removed an extension called "atlas speed dial". Since then, I haven't been able to get a tab to open. I uninstalled and reinstalled Firefox. It recognized that Firefox was on my pc before when it reinstalled. I had some tabs open and organized. I tried to recover tabs. I tried just using a new window and opening new tabs. Finally I just uninstalled for good, unless someone can tell me how to fix this issue. I'm using two other browsers. Luckily, when I installed another browser I'm using, I decided to temporarily set the new one as my default. I've setup several shortcuts and organized my desktop since then. So all of the shortcuts work through the other browser. But, I'd really like to still be able to use Firefox and especially would like to restore my open tab organization.
