Firefox recently updated and Face Book looks wrong. I've gone through all of the trouble shooting in "Web sites look wrong"
I cannot get Face Book to display properly in Firefox. I've done lots of trouble shooting. All of the "Web sites look wrong" troubleshooting. Very frustrating. Other web sites display properly. Not Face Book. Help! I love Firefox!
Woo-Hoo! Started Firefox in Safe Mode and disabled everything. Went through the Preferences check list of potential problems and double checked all of the settings, restarted Firefox, in plain default mode and wah-la, everything looks right again in Face Book! YAY! Then tried re-installing my theme, and checked FB again and it's all good! Thank You Firefox Support Pages! :)
