The 4 Best Firefox Extensions, Ever

Gmail Notifier

I couldn’t live without this extension. It puts a Gmail icon in your status bar, with the number of unread messages next to it. The icon lights up blue if you have new messages, and clicking it shows you your inbox. It’s much faster than waiting for gmail.com to load.

Web Developer Toolbar

This is a toolbar with tons of features for, you guessed it, web developers. The features I use the most are view/edit CSS, show passwords, find broken images, edit HTML, ruler, outlining (block level elements, current elements–useful for fixing your positionin), validate HTML, and resize. The 12 menus contain many additional features as well.
StumbleUpon

StumbleUpon is a toolbar and site useful for finding useful and interesting websites that match your interests. After telling the website what topics you are interested in, you can click the Stumble! button which will take you to a random site. You can click the I like it! or Not for me buttons to influence which websites it will show you in the future, as well as affect how often it is shown to other stumblers. The SU website also has community features such as friends, messaging, and groups.

Adblock Plus

Ever been annoyed by all the ads which slow down your browsing? If you’re like me, you are. This extension blocks document elements of your choice (scripts, java, images, Flash, etc) from loading and displaying. After selecting a subscription (EasyList is the most popular, and blocks most ads on English websites) you can also choose your own elements to block, or disable ABP on certain domains or pages.
