When attempting to play some videos with Firefox browser, mainly from X (Twitter) I receive "This video can't be played." However, I can't play them with Safari either. But it will play on Safari on another computer. I don't know what is wrong. Could it be some settings on my computer? I'm not a computer ace but know some things. Thank You for any help/ advice.
