The Facebook Messenger plug-in from Mozilla - the company behind the popular Web browser Firefox - allows the users to save their valuable browser space; giving them the advantage of getting their notifications and chat without having to actually open the social network's website.

Marking the first product of Mozilla' efforts to integrate more social features into the Firefox browser itself, instead of having them embedded inside Web apps and tabs, the Facebook Messenger plug-in essentially adds Facebook users' chat, notifications, and activity feed to the standard interface of their Firefox browser.

Helping the users remain constantly connected, the new Facebook Messenger plug-in - which is a part of the "Social API" - can potentially lead to several other types of permanent social add-ons.

The plug-in apparently has the potential to facilitate collaboration in a work chatroom or even probably help users monitor their Twitter feed. In addition, it might also be possible that the sidebar gives the friends of Facebook users the recommendation of the page they are viewing.

Given the advantages of the Facebook Messenger plug-in from Mozilla, those Facebook users who remained logged on to the social network will clearly like the idea of not having to keep an extra tab open; while power users may lament that they have to relinquish permanent space on their screen for social functions!
