Neither Firefox nor the profile manager will start. In my task manager, the process is using 50% of my cpu but does nothing. I love browsing with firefox, how can I fix this?
I've tried restarting my computer, the I tried uninstalling and reinstalling, then uninstalling, erasing all firefox files and folders, then restarting and reinstalling. I've also tried opening the profile manager to change my profile. After reinstalling a few times and trying to open the profile manager before launching firef0x, I got the firefox has crashed window and the process in the task manager is still using 50% of my cpu. The most recent expunge then re-download pops up a "file is corrupt" error and won't even install the program.

Kill those processes that you are seeing, including any plugincontainer.exe, only once firefox has stopped running should you try to update it.
Totally unexpected instances of firefox running may sometimes be the result of malware activity.
