Hey folks, I use messenger in Facebook every day, just access it by clicking the icon in the top right of my Facebook screen (on MacBook Pro). But today, when I am in Facebook, if I click on the icon, or just click on any of the names in my 'chat' list in the lower right, it now opens a new tab/webpage asking me to sign in separately to messenger. Anyone else getting this? Is it something new that can be turned off?? I've attached a couple screen shots of the tabs that automatically get opened when I click the messenger icon in the top right of FB, or click the name of someone in my chat list on the bottom right of the FB page..
