Geez, dunt get so defensive. It was an "FYI". Nothing more. I could care less what browser anyone uses.
Just don't think FireFox is bullet-proof. It is software and no software is perfect.
Most people will never have a problem with any browser. I know I have not and have been around the Internet longer than most people. But I do a lot of things, right up front, to prevent problems instead of accepting the defaults (which pretty much will gaurantee problems).
