Create a new profile as a test to check if your current profile is causing the problems.

See "Basic Troubleshooting: Make a new profile":

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.

If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Tried creating a new profile (which succeeded), but when FF was restarted, it crashed. It started with several tabs trying to load, which leads me to believe it's have trouble with one of the existing pages from the original crash (my guess: Google Calendar).

I've tried to start FF in safe mode, but that doesn't work either.

Is there a way to go back to a previous working version? Shame on me for being on early upgrader (i.e. guinea pig).

This seems to be caused by Roboform. Installing the latest version 7.6.3 of Roboform should solve this problem.
