Also make sure your Windows is fully up-to-date.

I just got my first crash in safe mode.

Thanks, but I just went from 7 to a fresh 8 last week and did all the updates. I did a system filecheck too, it came back negative. Hard to see how I could have exactly the same corrupted files in my fresh 8 install causing exactly the same problems and it came back negative...maybe whatever is wrong carried over when I carried over my bookmarks and settings through Sync? If I port all my bookmarks to Chrome or Explorer, then do a fresh install of Firefox, then port the bookmarks back, might that solve the problem?

If its a setting problem, doing a refresh will retain bookmarks, passwords and remove all settings, add-ons.

Refresh Firefox {web link} is a LAST RESORT ! !

Refresh Firefox - reset add-ons and settings

If you're having problems with Firefox, refreshing it can help. The refresh feature fixes many issues by restoring Firefox to its default state while saving your essential information like bookmarks, passwords, and open tabs.
