The guys over at PCMech have put together a little article on how you can use Firefox extensions to customize your web surfing experience. I'm personally an extension lightweight, & I've got nine of 'em installed.

"The customizability of Firefox is probably one of the reasons that makes it my preferred browser. Unlike Internet Explorer, for which there are almost no addons with additional functionality available, Firefox extensions are a dream come true. Among the hundreds available extensions, there are real gems that add extremely useful functionality to the browser."
