Did you scan for virus, spyware/adware etc.?
What it found?
After viewing & posting on I site I've known & used for years, I left site by clicking "Home" in my most current Mozilla.Exactly as I do almost every night. Instantly, computer crashed and rebooted. Re-opened Moz. and found ALL 300+ carefully collected bookmarks were erased along with all set preferences, cookie settings, home page(blank),form fill in stored data, & virtually all contents of profile (excepting profile itself). All remaining settings had been reset to Mozilla defaults.(Home page now Mozilla, not blank).
Second persons profile on same machine un-affected as best as I can tell.
Additionally, epson printer (connected) froze up during 1st printing task after episode(printing out some instructions for Mozilla).
Also several Windows XP functions seemed affected and threw up warning balloons and comp wouldn't shutdown in immediate (normal) way.
After many hours, I retrieved Sept/05 archived bookmarks(+/-50) and imported them. Reset all, ran checkdisk and got all functioning again. All completed without re&re of Mozilla.
In 6 years using Moz., I have never had any problem of any kind with it. Complete disbelief!!
Has anyone heard of such a case or expierenced such a thing before?? What turned out to be the cause?
Just surprised that this came less than 1 week after my WMF attack & patching w/ WMFFIX.exe.Could Patch have affected Moz?? Moz does have a few plug-ins like Acrobat reader & Flash (Macromedia)which was/is disabled(to prevent drive by installs) unless needed.
Further Moz (_12) has IDN patch installed & History set to Zero days.
Thanks in advance for any tales or guesses !!
