Why does PayPal says my browser (4.01) has a known security flaw?

I received a message from PayPal that says:

"It looks like you may be using an outdated browser with known security issues.

Help keep your computer and your PayPal account protected by updating your browser today."

When I checked Mozilla, it says I'm using the most current browser. I don't want to login to secure website if there is a security problem with Firefox. I can't surf without Firefox! Please help!

This sounds like a fraudulent email and will not be from PayPal. PayPal never send emails telling you to download software.

This link from PayPal shows their advice concerning fake emails - https://www.paypal.com/cgi-bin/webscr?cmd=p/gen/email-security-outside

Mine was not an email. It was a security page on https paypal. I did a search on paypal while logged into my account & this page showed up. Not fraudulent. But I suspect that paypal didn't recognize this newer version of firefox & hence the warning page.
