To get started, just upgrade to the latest Firefox and then visit the Facebook Messenger for Firefox page and click “Turn On.” You can watch this video to see how it works.
Once you enable the feature, you’ll get a social sidebar with your Facebook chat and updates, like new comments and photo tags. You’ll also get notifications for messages, friend requests and more that you can respond to right from your Firefox toolbar.
Facebook Messenger for Firefox lets you chat with friends and stay connected with their updates wherever you go on the Web, without needing to switch between or open a new tab. You can chat with your friends and family while doing anything from shopping online for the perfect gift, cheering your team on in the big game, watching a video or just surfing the Web. Of course, if you’re not feeling social, you can easily hide the sidebar or even disable the feature.
The company says Facebook integration is just first of its social features for Firefox. Additional features and providers will be added soon.
