I installed Mountain Lion on MacBook Pro and now cannot reach gmail.
My single sentence question pretty much states my problem. I downloaded Mountain Lion operating system at the store and cannot figure out how to reach gmail using Firefox like I have done in the past. If you send info on how to do this to my email account (firstname.lastname@example.org) I will not be able to notice it unless you have a magic wand. I am currently using Firefox all of the time when I go online. If you need a phone number: 360-753-1481.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
