BrowserLab – Verify your pages in many browsers
Adobe has released a new Flex application called Browser Lab. It allows you to see what your web pages will look like in a variety of browser versions including FireFox, Safari, and Internet Explorer (versions 6, 7, and 8).
You can set up a side by side view, magnify part of the page, and select different browsers.
There’s an onion-skin feature that lays two pages on top of each other so you can quickly check alignment issues.
This tool is very helpful because it is so hard having access to multiple versions of Internet Explorer.
Here is a screen shot showing my home page in FireFox 3.0 and IE 7.0.
You do need to register with Adobe to use this tool. However, if you are already registered for BuzzWord (a collaborative document site) or Kuler (a color scheme tool) than you have the userID/password you need. Here’s an article I wrote on Kuler.
