I am also experiencing this after running updates this morning. I am unable to browse to www.google.com -- I have not attempted other sites.
What I have tried: Moving profiles/extensions aside: mv ~/.mozilla ~/.mozilla-bak Running in safe mode: firefox --safe-mode firefox -safe-mode I'm not sure which is right but I tried both. I then realized I had copies of firefox running from before the upgrade. I closed them all, killed any firefox processes with kill -9 and moved my profile back. This worked, it ran a mozilla updater and has been fine.
