Mozilla closes by itself...?

[hhh]

Im currently using Mozilla to surf the web, but once in a while the Mozilla would popup a Netscape Agent and once i close it, it closes all my Mozilla windows...is anyone else experiencing the same problem? please help, it closed an important site (school project source) while i was doing work and im unable to find the site again...

It shows "Faulting application mozilla.exe, version 1.7.20050.25981, faulting module unknown, version 0.0.0.0, fault address 0x00000000."

Seems like theres some code on that website crashing your browser. Unless you can change the code on the site, i'd just use a different browser for that site.
