Upgraded to Firefox 13 last night. After I did this, Firefox formats several common web pages such as CNN, Facebook, Mozilla home almost unviewable. Gmail won't even load now. Below are links to screenshots. I have reset my cache, reinstalled a few versions, disabled addons and nothing has worked. Help?

Try reading the article Websites look wrong or appear differently than they should. Follow all the steps in it. If that doesn't work, try using the new reset Feature in Firefox. Refresh Firefox - reset add-ons and settings. It should take care of this for you.

Make sure that you aren't blocking CSS files.

Clear the cache and the cookies from sites that cause problems.

"Clear the Cache":

  • Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"

"Remove Cookies" from sites causing problems:

  • Tools > Options > Privacy > Cookies: "Show Cookies"

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).

Resetting Firefox fixed the issue. Much appreciated.
