11 Must-Have Add-Ons for Firefox 4: Online Collaboration«

One of the best things about Firefox is the huge number of useful add-ons that can be downloaded for it, enabling users to customize the browser to their needs. Some time ago, we put together anofficial WWD add-ons collection for Firefox, gathering together our favorite add-ons at the time. The speedy Firefox 4was released this weekand some of you may be giving it a try, so I thought I’d update the collection. I’ve removed those add-ons from the list that are now redundant or incompatible with Firefox 4, and added a couple of newer favorites:

1. Adblock Plus. Gets rid of annoying adverts and auto-playing videos. You can subscribe to filter subscriptions in dozens of languages which can  automatically configure it for purposes ranging from removing online advertising to blocking all known malware domains.
2. Better Gmail 2. Gina Trapani’s extension adds a bunch of useful extra features to Gmail, like hierarchical labels, an unread message icon on your browser tab, file attachment icons and more.
3. Download Statusbar. View and manage downloads from a tidy statusbar, without the download window getting in the way of your web browsing.
4. Gmail Manager. A Gmail notifier for multiple accounts; it allows you to receive new mail notifications, along with the ability to view account details.
5. LastPass Password Manager. A free online password manager and form filler that makes your web browsing more secure.
6. Greasemonkey. Allows you to customize the way a web page displays or behaves, by using small bits of JavaScript. You can write your own scripts, or download one from the hundreds available athttp://userscripts.org.
7. Read It Later. Save pages to read later with a click, then  when you have time, access your reading list from any computer or phone, even offline.
8. Shareaholic. This add-on provides an easy way to share interesting links using Facebook, Twitter, Evernote, Bit.ly, StumbleUpon, and more.
9. After the Deadline. After the Deadline is an intelligent grammar, style and spell checker. It works with most web sites.
10. Web Developer. Even if you’re not a web developer, this extension offers a raft of useful features: manage cookies, change up styles with CSS, adjust form options and much more.
11. Awesome Screenshot. Diigo’s handy screenshot tool lets you capture the whole web page or any portion, annotate it with rectangles, circles, arrows, lines and text, blur sensitive info, and then share the output.
