I found a really cool Firefox addon called FireQuery. This addon enables you to inject jQuery into any web page. This is a nice way to see how any web page behaves with jQuery.
Normally I would write a small article on how to use this technology, but I felt like doing something different so I made a short screencast on FireQuery and how to use it. Hopefully you’ll find it a useful tool as well.
You can watch the screencast here or can see it below:
