Hello, I have a problem with Mozilla Firefox. It started on August 11 2010(yesterday) The problem is that nothing is visible on my add-ons box and on the plugins box. I didn't have this problem before. All of a sudden it happened. The add-ons which Mozilla suggests are not visible, the installed pluging for Mozilla Firefox are not visible......Totally the whole content is not there except the tabs are visible. I used a program called Tune-Up utilities on the day the problem started. But I don't know if it is the problem of that program. If you want, I can take the screenshots also.
