Firefox 18 will not open for until it unsuccessfully tries to load an update after Windows reboot every time.
Each time I reboot my computer, Firefox 18 will be working in the background after I double click the icon. It does not show up in the task manager. If I double click the icon several times some minutes later, it will finally open up all the windows. The first window will say that an update was unsuccessfully loaded, and it will try again. When that fails, then I close that window and I am good until I reboot again.
I have already tried resetting to default. I also completely uninstalled it with all my personal settings and then reinstalled it.
The trouble remains.
