My windows7 home premium system seems to be running good (I keep it very current, checking for windows updates every morning and installing all important ones immediately) as well as java and adobe updates, and naturally, all firefoxupdates, automatically) I do have occasional firefox crashes -- maybe two a month or thereabouts -- but infrequent and they have never created any big problem that I can see. HOWEVER, recently while closely watching and timing a Norton 360 Premiere Full system scan, I noticed that for over 30 minutes, Norton 360 was running going through Firefox Crash reports and dumps. It seemed like a huge number of Firefox Crash Report and file system objects. Like an accumulation of that many must have been every one since I bought the PC new 3 years ago! Is that normal? Can I clean out/delete all those? How can I do that?
