I just read the footer to an email from PayPal on my iPhone. Apparently, the folks at PayPal haven't gotten around to an update of the text in their email sends for quite awhile as they're still recommending Netscape as a browser. Netscape? what's that.
NEVER give your password to anyone, including PayPal employees. Protect yourself against fraudulent websites by opening a new web browser (e.g. Internet Explorer or Netscape) and typing in the PayPal URL every time you log in to your account.
"By the end of 2006, the usage share of Netscape browsers had fallen, from over 90% in the mid 1990s, to less than 1%." -Wikipedia
