I just had to. As most of you know, FireFox 3 has just been launch and let's say: it doesn't lack in features. However, FireFox, being an open-source project, has a feature to get even more features: Add-Ons.
Add-Ons are scripts that run alongside FireFox to make your browsing experience customized to your own tastes and habits. But now that we know about the feature that gets features, we need to know about the feature that gets features that gets even more features: GreaseMonkey.
"
Greasemonkey is a
Mozilla Firefox extension that allows users to install
scripts that make
on-the-fly changes to most HTML-based
web pages. As Greasemonkey scripts are persistent, the changes made to the web pages are executed every time the page is opened, making them effectively permanent for the user running the script.
Greasemonkey can be used for adding new functionality to web pages (for example, embedding price comparison in
Amazon.com: Online Shopping for Electronics, Apparel, Computers, Books, DVDs & more web pages), fixing rendering bugs, combining data from multiple webpages, and numerous other purposes. Well-written Greasemonkey scripts can integrate changes so well that their additions appear to be natural parts of the web page."
By Wikipedia (where else?)
So GreaseMonkey will use scripts to get even more features, and these scripts are found at:
Userscripts.org
For example, I just found a script that will completely delete the timer on RapidShare - how great is that?!
Now all you need to do is post your favorite scripts below...
