Eric Johanson has reported a security issue in multiple browsers, which can be exploited by a malicious web site to spoof the URL displayed in the address bar, SSL certificate, and status bar.

You can test your browser for this vulnerability at the Secunia site. Firefox does get spoofed and until Mozilla comes out with a fix be careful clicking on links to websites with sensitive information like Paypal or your bank’s website.
