firefox-logo2-150x150This is a quick overview for those new to Firefox: Add-ons are little free tools that make your application experience better and easier. Add-ons don’t stop at browsers, either. Email applications like Thunderbird have them, too.

Just go to Firefox add-ons, browse, click “Add to Firefox” and click “Install” in the popup window. Once installed, you’ll need to restart Firefox to complete the process.

Some of the them are here:

Adblock Plus — No. More. Popup. Ads. Or auto-playing videos. You can easily download a Filter Subscription. You can create your own filters to block ads on specific sites.

Better Gmail 2. Folders4Gmail helps you to have labels in folder-like sub-folders. It is the replacement of attachment icons. You will see the Word’s blue ‘W if your document is of Word.

Download Statusbar. Downloads appear across the bottom of Firefox where they don’t intrude. When you’re ready to open one, just double-click the relevant filename in the status bar.

Firefox Environment Backup Extension (FEBE). A backup tool for an application is worth because it restores data with little effort. This one backs up your add-ons and rebuilds them.

Long URL Please. This add-on automatically expands shortened URLs. Even if you can’t see the full URL, you can mouse over the link to see the full link tooltip-style.

Print/Print Preview. Adds a print icon to the tool bar with a down arrow giving you the choices of Print, Print Preview or Page Setup. This add-on helps because it ensures I print only what I need and nothing more.

Read it Later. The add-on puts a checkmark in your browser. Click the checkmark to add the page to Read it Later, click it again to remove.

Web Developer. This toolbar has helped me out many times. You can disable Java, Javascript and colors, manage cookies, change up styles with CSS, adjust form options and much more.

Word Count Plus. Simple tool where you highlight the text, click the icon and see the word count. Now it just needs an added feature to count characters for Twittering outside the box.

Xmarks. A bookmarks synchronizer that works between computers and across networks. It can synchronize passwords, give you information about a web page and create separate profiles. You can have a profile for each computer so you can pick and choose which bookmarks to display at each location.
