Mozilla’s Firefox was always a threat to rest of the browsers, since it’s early launch. Mozilla CTO, Brendan Eich may not agree with mobile web browsing, but Mozilla as a whole do not have any lack of innovation ahead of their competitors.

After breakneck growth during its first two years on the market, Firefox has become the Web browser of choice for about 15% of PC users. After its 2004 release, with features like easy-to-manage bookmarks, tabbed browsing, and an effective pop-up ad blocker, not to mention dozens of unique features never seen before, Firefox popularity simply just explode.Microsoft’s IE catch up with those two years later, in IE7 in 2006. Which makes FF and IE head to head.

So once again for taking the lead, obviously Mozilla has started playing with ways to chop in features of popular Web 2.0 right into their browser. Mozilla Labs is where all this experimental cooking going on. Now just few days ago this cook house announces it’s first delicacy, The Coop. This application, you can say basically an add-on, which will allow users to share favorite Web site links with friends by dragging a page right onto a avatar/photo of the person. So in simple word, all users within a coop can share links by just drag & drop all within FF browser.

This was just a particle of what Mozilla have in mind with this new feature. Work is underway to develop share photos from Yahoo’s Flickr site and videos from Google’s YouTube, and a tool that lets users update their online status so Facebook friends know whether they’re available to chat.

Mozilla lab is also coking other grand delicacy, “Operator” that lets users post contact information or calendar entries to a Web page in a way that desktop software and other Web sites can import. Operator is a perfect example of use of Content Label/Meta Data.

Adding popular social networking feature on the browser was a smart move by Mozilla, sooner or later you can bet other browsers are also following this path. Just question is how far are we from true semantic web?
