Only a couple of weeks ago I switched from IE to Firefox, but not because of security issues. Though my hardware is up to date IE just was too slow and heavy. Apparently IE consists of parts scattered all over my C drive, which makes the damn browser respond slowly if the hd is a little fragmented. Also, the amount of RAM IE eats is horrible. I like to have multiple browser windows open simultaneously, which means multiple iexplore.exe applications running at the same time, reserving 17MB+ RAM each! Firefox on the other hand needs only one exe running. Too bad I only tested my personal web site with IE. When I switched to Firefox I noticed that the site doesn't look right with any other browser.
