Did you get a crash with the Beta version? Please post it.


Start your Computer in safe mode with network support. Then start Firefox.
Try Secure websites. Is the problem still there?

Beta Version? It was whatever version the last update installed.

I have fixed it but only by completely uninstalling Firefox, deleting everything associated with it and reinstalling from scratch.

I tried installing a new version on top of the existing one several times but it crashed mid way through the install.

Fortunately, everything has re-synced and it seems happy for the moment.
