• Quit and then reopen your browser

If you're having trouble viewing videos on your phone, make sure your phone is able to play videos. If your phone doesn't support videos it will show a thumbnail but won't play.

 

Try disabling Flash completely. Microsoft Edge does support HTML 5 video and audio, which is to become the new standard for WWW multimedia viewing. Edge has less support of this than Chrome or Firefox, but enough support for most all sites, including Facebook. If Flash is disabled then HTML 5 will automatically be used.

Another thing I've noticed on Facebook is that sometimes a video will not stream properly and it's due to Facebook itself, not the browser. Thus reloading the page or closing the browser and returning to the page enables the video to play. Facebook is a very high traffic site and though they are capable of handling the traffic, sometimes there are bottlenecks in the internal Facebook network.
