A few years ago I made the switch from Microsoft?s Internet Explorer over to Mozilla?s Firefox browser, a free open sourced browser. At the time there were some huge advantages such as tabbed browsing (allowing multiple web sites to be loaded into one window) and an integrated pop-up blocker, features that the newest version of IE also has.

What IE doesn?t have, and probably never will, are extensions. What are extensions you may ask? Extensions are small, generally free additions that you can use to enhance your web experience. There are literally hundreds and hundreds of them out there but not all are useful. Here are the best I?ve been able to find:

Stumble Upon is by far my favorite of all the extensions I?ve installed. It?s like surfing channels on the web. A small button is displayed in your tool bar, and when you click it you?re taken to a site that matches your selected interests that another user has recommended. You can then rate the site, either up or down. It?s a great way to find some fun new sites.

Colorzilla is a great tool for anyone who develops websites or does digital art. Just click the icon in your status bar and you?ll be provided with the RGB codes and the HTML code for the color. Very cool.

My Stickes lets you put post-it style notes on web pages and access them from the MyStickies site. Not only that, but they show up right where you left them so you can even notate why the heck you wanted to keep it in the first place.

Del.icio.us is another favorite place manager that allows you to access your pages from any PC. It?s a bit more user friendly than MyStickies and also has WordPress plug-ins so you can share your favorites on your blog.

That?s it for now. I?ll add more if I find start using any new ones.
