I have no sound in many videos in my Firefox. Seems like they need codecs.
I alredy have OpenH264 Video Codec, it works fine for YouTube. But which codec packages I can install?

Hi.
From on version 43 Firefox has been using ffmpeg to play back the multimedia content.
You should check that your media-video/ffmpeg has compiled with the required USE -flags. Especially look for the flags named: aac, vpx, x264, x265 and opus.

When I compiled Firefox I noticed that he used gstreamer. |

You have to compile firefox with the "ffmpeg" USE.
I don't know what, but something as changed in gstreamer. I've the same problem. |

Do you use PulseAudio?
Give me an example web site that does not work with your Firefox so I can test it.
You can run "dmesg -w" in terminal before you start Firefox. Then go to the site that does not work and see if some error messages appear to the terminal.
Also paste the output of equery u firefox | grep -v 'l10n'.

Sometimes Firefox crushes when I go to some site with media content. Like the YouTube, but not when I'm watching a video, but when I open main YouTube page with advertisement.Firefox just crushes as soon as page loads, it doesn't matter do I played ad or not.
There are only low quality videos on YT, I can't switch to 1080p for example. As I know it means that there are no required codecs.

If you navigate to youtube.com/html5 is everything ticked? I think I know how to solve your resolution problem at least. |

i think you don't need vpx x264 x265 flags, as they are for encoding. i don't know about opus though. you only need decoders for playback. i have none of the above flags enabled, and i have audio & video on almost all youtube videos and facebook. http://youtube.com/html5 shows all 7 boxes ticked. i don't have flash installed.
