Problems reproducing videos in differents pages with Firefox

Hi! Recently I’ve had some problems with my Firefox. When I try to watch some videos, like in youtube, I can’t because it says that there was an error trying to reproduce the video, even in Crunchyroll this problem still existing. I have to say that a few days ago I change the direction of my /home/ folder to another drive (I had /home in an HDD and now it’s in a SSD), the problems started there.

I tried the following things:
-“Refresh firefox” the first option that firefox recommend you.
-Clear all the cache.
-Uninstalling and reinstalling firefox.
-Open firefox in troubleshoot mode.

No one of this solution works to me, please help me.
