  • Facebook is one of the most leading social media platforms. The revolutionary launch of Facebook Messenger (app and website) made it easier for the users to check their messages without opening the Facebook page. Many users wanted to have the Facebook Messenger for their desktop PCs (as a browser addon) so that they could check their messages, talk to the friends and have group chats etc. without the need of going to the Facebook website. App for Messenger™ addon is the perfect solution for those users.

    App for Messenger™ is a lite addon for the browsers (Chrome, Firefox and Opera) that provides easy and instant access to your messenger page. This addon is intended to operate similar to Google Chrome Apps within the browser. In simple words, it opens in a stand-alone popup window. Once the add-on is closed, App for Messenger completely clears off and won't have any further background activities that can disturb your work. This lite behavior makes this addon very easy and handy to use. Furthermore, the addon popup has a built-in "Always-On-Top" feature which makes the window remain always on top of other windows and enables you to do multi-tasking without causing any hassle of switching the windows. It is important to note that, App for Messenger™ addon is not developed or created by the official Facebook or Messenger website. It is basically an unofficial app that has been developed and maintained independently and unofficially by its author. The official Facebook Messenger software is only released for the web and the smartphones. This browser addon is a simple way to access the Messenger through the desktop PC or MAC. This is available for different browsers and by far, it works best on all especially on Mozilla Firefox. This addon is a must have for all of you who want to be in touch with their friends without even missing out on opportunities to work.
