I ran Trend Micro Titanium Maximum Security 2013 System Tuner and lost all the info, gadgets, etc. and even my email (Gmail) access. I was left with a black, blank page. I opened up Google Chrome and everything is still in place. This happened 3 days ago. So, yesterday I ran the system tuner again again as per my own comments from last year....had sorted it out by doing it. Still nothing. This morning.....I opened Firefox (21) and surprisingly had my main desktop page but still without my email. When I tried to open the email on it's own I still got nothing....the computer seemed to try to open it, but got "stuck" and the "loading" bar that goes from left to right never appeared. I could switch to the "slower" HTML version and the mail came up but prefer standard version. Checking on Google Chrome, everything is working just fine. I believe the Firefox Version 21 had only just been updated? Perhaps that is at the core. I really prefer Firefox but will have to continue with Google Chrome until this problem perhaps sorts itself out. Since it is loading properly on Google Chrome I don't want to set everything up again. Any suggestions?
