I have attempted launching FireFox in "Safe Mode" though it still crashes/will not open in. Before this it would not open at all, no crash report's, no nothing. Then I reset my computer to a prevous update version. And now it gives me a crash report.

(I have attempted uninstalling and reinstalling FireFox and it still will not open, and I am no longer getting crash reports)

Hi,

You can try to clean install a fresh copy after uninstalling the present version via Windows Control Panel Programs and Features. While uninstalling make sure to choose deleting the preferences and folders. Please also see this regarding problems with security software.

To backup important info which can be restored later, please see this. Some of the important files could be places.sqlite which holds the bookmarks and history, key3.db + signons.sqlite which are needed to restore the saved passwords etc.

I am no longer receiving crashes reports but it is not opening either (After unistalling and reinstalling).
