You have not stated what solutions you have tried so far.

Do you have a N or KN edition of Windows 7?

if so then you may be missing the Media Feature Pack for Windows 7 N. It provides the codecs needed to fully support the HTML5 players like the one used at Youtube and many other sites instead of using Flash Player Plugin.

A place to test is at https://www.youtube.com/html5/ as all checks should ideally be blue.

See https://support.mozilla.org/en-US/kb/fix-video-audio-problems-firefox-windows for link to Media Feature Pack for Windows 7 N.

Windows for markets like US and Canada comes with this installed.

Chrome can work in this case because they kind of cheat by coming with its own codecs.
