When it comes to web browsers, the one that stands out the most is Firefox. It has a wide variety of add-ons, themes, and settings which are very customizable. The most powerful part — the add-ons — is where the true beauty lies within Firefox. One add-on in particular — Greasemonkey — is extremely useful. It can change any website to display extra information, re-organize site layouts, and unlock “hidden features” of a site to make it easier to use. For example, a website like Grooveshark has a humongous advertisement panel on the right side of the screen. In my opinion, it gets in the way when using their site. With Greasemonkey’s Grooveshark script, it completely removes that advertisement panel so you’re free from distractions. That’s just one example of how you can use Greasemonkey. Other Greasemonkey scripts that I use almost daily include De-Sidebar Facebook, Remove Digg Ads, Flickr Buddy Icon Reply, Flickr Ad Removal, Flickr Titles + Descriptions Batch Tools. For more Greasemonkey scripts, please visit Userscripts.org.
