This afternoon I watched an old video of mine on YouTube. Afterwards, YouTube now only gives the option of 360 or 720p playback. Internet Explorer will play the same videos at 4K, and I was able to watch 1080 up to 2160p before watching this old video, how do I fix Firefox?

http://youtu.be/Je0sQwVynzI There's the newest video, with a 4k playback option, I don't want to post the old video that caused the glitch but it's the first video in my channel.

Please help!

After going into about:config I did 2 things:

media.mediasource.enabled set to True

then added

Right-click and select New > Boolean Name preference media.mediasource.ignore_codecs Set value to True

A ton of technical stuff just from playing an old video! Is there a simpler to fix this without hard setting things in the configuration?

And now I cannot replay youtube videos! It will pause if I try to go back. Considering a video will auto play so I will select the highest quality then scrub back to start this happens usually every time so this fix is worthless.
