This and the Security Vulnerability in FF 3 when going to spyware infected sites.. more reasons why I like a properly configured IE .. especially IE 8. Using IE now for 12+ years.. 0 spyware, virus, Trojan, or tracking cookies..
I put FF on my old rig for a week.. FF2 I believe.. and within a week, I had 2 Viruses.. not something to convince me to switch over.. now that IE 8 is Acid 2 compliant, and is being patched up for Acid 3 for the Final Release.. FF still has a long way to go.. IE was Acid 2 before FF and IE will be Acid 3 before FF.. and if Safari can't get things together soon, IE will pass them up as well.
IE 8 (in IE 8 compliance mode) supports all the Alphas in PNG now even in IE 7 compatibility mode (non compliance mode).
I never did like the FF look. It is too jumbled for my tastes.. IE looks good out the get go, and simple right click commands allows you to configure on the fly within 1 or 2 seconds.. I'm not sure how FF is on this.. but IE ito me is extremely user friendly, especially IE8.
