Internet Explorer

Microsoft's answer to Netscape in the Browser Wars. Any version up to (and including) 6 is not W3C standards compliant (which, of course, does not mean it isn't a de facto standard). Rumors of security holes on it are, sadly, far less serious than the actual truth.

Sadly, all the intranet corporate sites I know are designed solely for using this junk.

• Maxthon - adds tabbed browsing and other Firefox-like features. Might be an option for some people.
• IEs 4 Linux - Lets you install IE on Linux (atop WINE) - recently improved, but still does not enable SSL support, so no dice.
• Bugs to be fixed in IE7.
