This site is awesome for a web developer. It allows you to see what your pages will look like across different browsers and different operating systems. It will even allow you look at them in specific screen sizes and color depths. Overall a very helpful tool.

Test your site on different browsers - nice free tool for web developers - It's hard to test your site on every browser version, and inevitably something will be broken on something.<a href="http:// Browsershots.org" target="_blank"> Browsershots.org</a> tests out your sites on most Linux, Mac and Windows browsers, and returns screen shots so you can see if anything is broken. Very useful tool.
