Test your website in different browsers

You can use http://www.xenocode.com/ to run various applications directly from the web. Go to http://www.xenocode.com/Browsers/ and run any browser you like to test your website with. Unfortunately it only works with windows and internet explorer.

Another very useful site to check browser compatibility is http://browsershots.org. When you submit your web address, it will be added to the job queue. A number of distributed computers will open your website in their browser. Then they will make screenshots and upload them to the central server of Browsershots. It supports Windows ( Firefox 1.5, Internet Explorer 5.0 and 6.0 ), Mac (Firefox 2.0, Safari 2.0 ), Linux ( Iceweasel 2.0, Konqueror 3.5 ).
