Wow. Interaction between firefox and chrome video playback is really weird. Could it be something about the network?

Can you like to a specific video? These seem to be youtube embeds. Do videos on https://youtube.com work?

Any youtube video.
After:
$ sudo pm-suspend
and resume PC operation old opened video or new opened doesn't played. I see image, progress bar show that stream downloaded.
With "pm-suspend" I can reproduce in 100% cases issue.

I try to open new profile after pm-suspend:
$ firefox -P test -no-remote
and video also doesn't played.
My suggestion that Firefox can't properly re-initialize H.264 or WEBM playback.
I have GeForce 8600 GT video card and enable hardware decoding:

Further info. Once I run any video player (vlc/mplayer) - Firefox start reproducing video stream.
I try to open an H.264 (that uses HW decoding) and flash VP6 (that doesn't use HW decoding) video after "pm-suspend".
Seems that Firefox have broken re-initialisation code for playback under Xorg.
Is it reproducible when you set media.gstreamer.enabled=false ?

After reboot I live without issue one week. Problem appear randomly but if happen it is reproduced after each suspend.
Next time then I had issue I try to set "media.gstreamer.enabled=false".
> Is it reproducible when you set media.gstreamer.enabled=false ?
Today after suspend issue reproduced.
I check `media.gstreamer.enabled=false` and problem present.
===========================================
Now I am sure that issue come from VLC media player.
If I suspend with vlc paused (even on MP3 file) - Firefox can't reproduce any Youtube video after resume from suspend.
If I close or un-check pause in VLC - Firefox start reproducing video.
Other players and Chrome browser able to start playing even with VLC running between suspend.
Firefox can't.
100% reproducing. Debian, Intel x64, Intel HDA, GeForce 8600 GT, 45.0a2 (2015-12-18).

Today playback hangs even if player is not loaded. I finish watching with mplayer2, close it and suspend.
After resume from PC suspend Firefox wouldn't able to play any HTML5 video until I run external mplayer.
Note that with VLC I have 100% reproducibility (see above). But today behavior also strange and make me think that bug related to GPU acceleration and PC suspend/resume. Firefox can't handle hardware re-initialisation it properly.
My guess would be a pm-suspend issue rather than a Firefox issue. Try:
# pm-suspend --quirk-vbe-post

Nope. `--quirk-vbe-post` option doesn't solve issue. 100% reproducibility.
Also this option is dangerous, from pm-suspend(1) man:
This option will attempt to reinitialize the video card when
resuming from suspend, using the same code the system BIOS
uses at boot in order to initialize the video hardware. Not
all video cards need this, and using this option on systems
where it is not needed can cause a system to lock up when
resuming.
