Browser Support Info
 
Windows
( All flavors )
 
Layout design is based on Webmonkey.com's browser support charts, except that I converted it to CSS.
Sources:

Webmonkey.com - lots and lots of good info
Index DOT html - Good breakdown of browser version histories
www.mozilla.org - Mozilla has a lot of web developer info well beyond just for their browser
Quirksmode - By far the most comprehensive and best put together site on subject of browser support.
psychedelix.com - 3 pages of more user-agent strings than you knew existed. (Still not complete)
CodeBitch (macedition.com) - info on Mac support
Netscape devedge - includes the original MasterGrid charts, plus more
www.teacherjohn.com - lots of resources, links, tutorials. A former teacher of mine
