youtube videos won't load starting from some positions

For some youtube videos, firefox will not start loading at some time position.

For instance, this one :

If you place at 0:50 for instance, it will never load. But it loads at other positions, like 1:50.

I also reinstalled firefox completely, and I have this problem at my job computer too (2 windows 10)

I don't have this problem in chrome.

Any solution ? Is this a firefox bug ?

Make sure you are not blocking content.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Those 3 links won't help.

Have you tried the link ?

Go at 0:50, you'll see that the playback will NOT load. But it works with Chrome.

Is this a known bug ?

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

I already tried removing all cache and cookies, safe mode, and new profile. Problem still there.

I disabled 3d acceleration and restarted firefox Problem still there.

To be clear: The link does load, but it will NOT load if you position at somewhere around 0:50.

Since it works with another html5 player (using addon "HTML5 Video Everywhere!"), the issue is with firefox having problem with the youtube html5 player.
