Mozilla is making it official announcement that the Facebook Messenger experiment is live for Firefox Beta users. The app had been available over the weekend and Firefox Beta and Firefox Aurora users could have started using it already, but Mozilla only now announced it.
According to Mozilla announcement “For the last few months we’ve been building the Social API – a way to allow you to plug your favorite social sites into Firefox – and we are ready to start our first Social API test with Facebook Messenger for Firefox.”
The feature has been available, if you knew where to look, for a few days, but it should be much more visible now. By default, if you’re running Firefox 17 Beta or Firefox 18 Aurora and visit Facebook, you could be invited to install Facebook Messenger for Firefox.
If you don’t want to leave things to chance, you can visit Facebook’s Messenger for Firefox page and turn it on in your browser.
If you do enable it, everything should be familiar, the friends list is identical to the one on the site, the chat window too.
In case you’re wondering, you’re not logged into chat by default, you have to enable it and you can disable chat or make yourself invisible without “turning off” the entire Facebook Messenger.
