Is anyone having problems watching Youtube videos in Firefox?
July 31st, 2016
Are you using extensions or userscripts regarding videos or YouTube?
Can you try deleting the YouTube cache and cookie?
your problem maybe related to either your connection or youtube itself , i also experienced problems like that which is not related to browser. so wait 1-2 days to see if things change. on the other hand , i personally know 2 person who are having problems on youtube with firefox 40++ , i also have different kind of problems with firefox 40 but not youtube related.
Same problem here with FF 39.0.3
Sometimes a youtube vid will take 30+ seconds before it starts to play. Using Opera they start instantly.
Me too, experiencing sluggish video playback in firefox 40 but perhaps adblock + noscript addons are causing this setback.
