I have problem with play video on some site (example yapfiles.ru or smotri.com). But on youtube I have no any problems. I use Windows XP SP3 32bit I need install some plugin or change some setting? Or maybe playback H.264 not work in WinXP?

Will this fix ya up : https://support.mozilla.org/en-US/kb/fix-video-audio-problems-firefox-windows

Maybe you should move to the Extended Release as you will not get any further updates from Firefox 52 running XP https://www.mozilla.org/en-US/firefox/organizations/all/

Please let us know if this solved your issue or if need further assistance.

Misunderstanding as info shows just Firefox 52 when it usually includes the ESR after the number.

I mean I already use Firefox 52.2.1ESR and have this problem.

Firefox relies on built-in OS support to play (MP4) media files via the HTML5 media player. On the Windows XP platform you do not have native support for playing MP4 files with the HTML5 media player.

You can try if the solution listed here still works for you. https://www.msfn.org/board/topic/175591-enable-mp4-h264-aac-html5-video-in-firefox-on-windows-xp-without-flash/
