Firefox Addon of the Day : Greasemonkey

I like Greasemonkey and I hope you like it too. Greasemonkey is an Firefox extension that allows users to install scripts and change the HTML page with the scripts ( augmented browsing ). Greasemonkey scripts are "presistent" meaning they would remain every time on the webpage for the user.

Available for :-
Firefox
Flock
Epiphany
custom versions  for SeaMonkey and SongBird.

Similar Softwares :-
Internet Explorer - IE7pro, iMacros
Safari - GreaseKit
Google Chrome - Limited native support for greasemonkey.
