Can't get Mozilla right under redhat 7
I desperately need help although I'm not sure if this problem has to do with linux or just with Mozilla.
I've been using for a long time Mozilla under redhat 7.
Now, since yesterday, when trying to open mozilla mail and news, clicking on the left down button, I get a blank page. So, I lost the access to any mail folders. Also, my browser bookmarks vanished, although it is possible to create new ones. Actually, mozilla is working fine for internet browsing.
Sorry if this is a mozilla exclusive problem. If help is not possible here, I thank references of where gret appropriate help.
