Well I've never had any issues with Firefox, unlike I.E. or Safari nor have I heard of any. Get Safari, and get carpet bombed or have your Paypal compromised. Run I.E. and have your browser taken over. I do use I.E. for my general computer use but never go online. I keep Foxfire loaded but not as the default to even protect my computer more. Use it as a internet browser only. Even if they invade Foxfire it is basically a stand alone, so they can screw with it and nothing else.
