One of the RB'ers told me they have been using DejaClick, a Firefox extension, for automating test scenarios on the web sites.

Basically, you have the tool record your clicks and actions. You then save that to a file and you can play it again. For example, if I want to make sure my contact us form works, I can run a test scenario for it and play it over again when I want to run the test. It saves time. Here is a video that shows it in action:

So you can set this up to make sure certain features work on a site after you make coding changes. This tool will be heavily used here.
