I am not able to find the open Firefox on my Desk Top running MAC OS X (10.7.5). On a 2.7 Ghz Intel Core i5

How do I clear this issue in simple terms. Tried following other post but nothing works.

See:

Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.
