One of the greatest things about the Firefox browser is that any developer can expand its features and capabilities with a simple add-on. There are add-ons for everything—Twitter, Facebook, Stumbleupon, Digg, feed readers, price comparison, photos, music, and more. Today, every browser supports plug-ins and extensions.
Yesterday, cumulative add-on downloads passed the 2 billion mark. It passed the first billion downloads back in November, 2008. The first billion took three and a half years. The second billion took about 20 months. Many of those are never used again, but a full 150 million add-ons are used every single day at least once.
To celebrate the milestone, Mozilla has put together a collection of the 25 best add-ons. They include StumbleUpon, Glue, Cooliris, Xmarks, Kidzui, Firebug, GreaseMonkey, Adblock Plus, and Destroy the Web (it turns any Web page into a video game). Inexplicably, the list is missing Feedly, the best feed reader of all time.
What else should be on that list?
Firefox is a Web browser created Mozilla Corporation. Since its release in 2002 (as Phoenix 0.1, later named as Firebird then Firefox as of 0.8 to present), the browser has become one of the most popular Web browsers in the market, trailing only Microsoft’s Internet Explorer as of July 2009.
