Using an old browser? If you're planning to use PayPal, you might consider updating.
PayPal, one of the brands most spoofed in phishing attacks, is working on a plan to block its users from making transactions from Web browsers that don't provide anti-phishing protection.
The eBay-owned company, which runs a Web-based payment system that allows the transfer of funds between bank accounts and credit cards, said browsers that do not have support for blocking identity theft-related Web sites or for EV SSL (Extended Validation Secure Sockets Layer) certificates are considered "unsafe" for financial transactions.
Honestly, although some may consider PayPal's "threat" draconian, it's in your own best interest to switch to a "modern" browser. And no, it's doesn't have to be IE.
