The ongoing battle between web developers and the web browsers of the world is getting a little easier thanks to the help of Adobe BrowserLabs.
The recently updated web application let's users submit a url and return a screenshot of the page as seen by a majority of the possible browser/OS combinations. BrowserLabs is a simple tool that makes troubleshooting web problems much easier. In a matter of minutes you'll know what the unfortunate souls in your marketing department, stuck with IE 6 on their Windows 95 computers, are seeing on your website that you can't manage to re-create.
With upgrades and new features still being added, this looks like it will maintain itself as a current tool that should be a valuable part of any developers arsenal of weapons for browser combat.
