For the last six months or so, we've been doing the heavy lifting to build a new social capability into Firefox. Rather than force this integration, a set of features that might not be interesting to all of our users, we took a different approach and built an API that will allow sites like Facebook and others to provide social content to Firefox if Firefox users choose to receive it. If you're not interested in these new features, you'll never see them and they won't impact your Firefox experience in any way. If, on the other hand, you think you'd get value from carrying your social experience with you even when you're off of that site, you should give it a try.
Here's what some Twitter folks are saying about the Facebook integration in this first Firefox release with the Social API.
The new Firefox Social API and Facebook app is pretty awesome. Hopefully twitter hops on board.— Jack (@jackwmc4) November 21, 2012
Right so I'm using Firefox at work. And v17 has a mean social api that integrates Facebook's vital tools and chat. And I like it. I'm sorry.— Darryl Radcliffe (@darrylradcliffe) November 21, 2012
Upgraded to the latest version of Firefox, it has integrated Facebook messenger into it....saves me 20 seconds a day now— BrianWaldron (@ThatBrianW) November 21, 2012
Firefox Social API - very cool!! blog.mozilla.org/blog/2012/11/2...— Rob Wood (@automationtrail) November 20, 2012
Firefox 17's Facebook integration is fun. I can keep using chat no matter which page I'm looking at. No matter which page :|— albull (@albull) November 21, 2012
Firefox 17 has a Social API, which seems a more sensible way of doing things than a whole new browser like Rockmelt: blog.mozilla.org/blog/2012/11/2...— Peter Gasston (@stopsatgreen) November 20, 2012
Who's downloaded the new FireFox 17? What's the social integration like? Facebook Messenger in a sidebar sounds like a great idea. #TechRap— Josh Villanueva (@michaeljosh) November 20, 2012
