Firefox happens to be my favorite browser. I have used it for quite a while now, and use a variety of add-ons, Greasemonkey scripts, along with Stylish scripts to make it a better browsing experience. In this article, I will be listing the top 20 Greasemonkey user scripts that I use. For those of you who don’t know about user scripts, here is the best definition I can give:
Scripts are used to extend the functionality of existing web applications, web sites, etc., created by a community of developers. Greasemonkey scripts are considered to be a browser add-on that gives you the ability to integrate Javascript-based modifications to a site when you load it.
To use scripts, you will want to install Greasemonkey, which gives you access to thousands of scripts to use for a better browsing experience. Once you install Greasemonkey, you will also want to install another Firefox add-on ‘Greasefire’ to help you find scripts for a page that you want to make more user friendly.
Here is how it works:
Lets say you are on iGoogle and you want to have a different way of viewing iGoogle. All you do is right-click on the monkey face (Greasemonkey), and at the top of the list, you will see how many scripts are available for iGoogle. Hover to that menu item and click it to open the list. Here is where you will be able to see the name of the script, rank, update, and a description. You can also sort the list by name, rank, or update. When you find a script that you want to use, click on Install “name of the script” and it will bring up a pop-up window with a warning. Just click on Install if you trust the source. Once you have installed the script, hit your ‘refresh’ button to see the script in action.
If you decide not to use Greasefire, or are having problems with Greasefire (which I had been having since updating to Firefox 3.6), you can find specific scripts for Greasemonkey at http://userscripts.org which currently has over 45,000 scripts for you to choose from.
Now, enough about how scripts work and where to find them, let’s get to the list!
(NOTE: Most of the images will have the before and after shot. Some screens may not look exactly like yours, I use Stylish also – read about it in the next article.)

Facebook Fixer

Enhancements for Facebook: bigger profile pictures and photos, easier viewing of albums, links to download videos, showing people’s age and sign, google calendar integration, bookmarks, keyboard shortcuts & more. It’s fully customizable!
Note: If you do not have the new Facebook home page (new as of February 2010) you should wait until you get it before you install this new version.
Some other features include:
A new bookmark feature which allow you to add and remove bookmarks for any facebook page. They will appear in a new drop-down submenu within the top menu of every page. To add or remove a bookmark you first have to go to the page you want added or removed.
Use a keyboard shortcut for adding bookmarks: K (shift + k).
Logout link on the main menu so you don’t have to go to the “Account” submenu to log out.
A link to the Facebook Fixer config screen from the “Account” menu
Hide application, status and wall stories. Previously you could “block 3rd party applications” but hiding application stories should be more reliable and will not adjust the settings for Facebook account.
Hide feed items for all feeds, no longer just the “most recent” feed.
Hide specific sections of the left column on the home page.
A list of translators to the About tab of the config screen.
Big pictures popup to be above the menus.

TWITTER SCRIPTS

Helvetwitter

A simple way to read what’s going on with your friends and/or random strangers. It strips everything out of the Twitter interface save for the essentials: names, Tweets, and a box for updates. Instead of a ton of colors, you get three: white, black, and red. This is Twitter minimalism to the max.

Creates buttons next to each posting to allowing you to easily unfollow users on twitter.
