This is a very cool "plugin" for Firefox that i can see being abused to hell by spammers but I’m going to post it anyway. Selenium IDE is a Firefox Extension which allows you to automate, record and also playback everyday tasks in FireFox. Most people have a daily routine of sites they visit, blogs they read, and email accounts they check and now instead of typing URLs for hours you can go through them all with a single click of the mouse. The extension acts as a macro in a way so at first you need to record your daily routine. Once you record that into the extension you are able to save it and then load it up and with a click of a mouse replay it.

This video demonstrates how to record and playback tasks with Selenium IDE.
