A good reason to switch from IE

IE has a vulnerability that allows the owner of a page to disguise the location of a page in the IE address bar. In the example this at:
http://www.zapthedingbat.com/security/ex01/vun1.htm
the page appears to a Microsoft page, with the address www.microsoft.com. In fact it's nothing to do with Microsoft.

I must admit using the domain in the address bar to reassure myself before filling in any online forms. I now use Firebird as my default browser. The trick described in the above link doesn't work in Firebird. But maybe some other trick does. Beware!
