I updated to Firefox 14.0.1 and gmail will not open. Have been trying for several hours since the update. Other google sites work fine and I am able to open gmail with Safari, which makes me believe it is a firefox update issue.
This is the standard Firefox fix that does not work. The problem is not the cache nor is it the cookies. The issue is a firefox issue only and G-Mail can be opened in other browsers such as IE. This is so frustrating and everyone is still complaining there is no decent fix after many complaints. I've re-installed mozilla - still doesn't fix it.
