Up to a week ago I had no problems playing the videos on Facebook that were sent to me but now I am unable to play any videos. I checked the Facebook settings & video but this is very limited to what you can adjust and change ?? Does anyone have any good suggestions or has also had this problem, Thanks for any feedback !!!

Try updating your Adobe Flash.

Try.. on the address bar, you have a padlock, [in front of https//] right click on it to see if something is blocked..   Allow or Ask or Block is the options...  mine appears to change from time to time, so if something will not play the setting here have gone from Allow to Ask or block for some unknown reason..  

Some Videos now only use HTML5 player, be sure your Browser will also support HTML5 player.... [or download it] 

 

So say Adobe Flash is about to be discontinued !! ?   or so it was said about 9 months ago.
