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 Firefox 52.2.1 ESR I need install some plugin or change some setting? Or maybe playback H.264 not work in WinXP?
Additional System Details
- Windows Presentation Foundation (WPF) plug-in for Mozilla browsers
- User Agent: Mozilla/5.0 (Windows NT 5.1; rv:52.0) Gecko/20100101 Firefox/52.0
