OK, this one really made me crazy.
1st~ I uninstalled Mozilla Firefox 3.0.6,
2nd~ I searched for any hidden files in my system, program files and registry that were named Mozilla an/or Firefox and removed them.
3rd~ I Re-booted did a clean install of Mozilla Firefox 3.0.6
Problem was still there.
4th~ I Updated Java - Problem still there
5th~ I Searched my entire system for the msvcr80.dll driver and replaced all but one. The only directory which wouldn't let me replace the driver was,
And alas, the problem still there... waaa
OK, now that I've made you listen to all my woes,
HERE"S THE FIX!!!
Open Mozilla, go to TOOLS.
Then click on ADD-ONS
Now go down the list and DISABLE EVERYTHING.
Restart Mozilla and then visit all those problem sites where Mozilla would pop up the msvcr80.dll error message. Viola! no more problem!
Glad I could help everyone.
