Firefox stopped playing some vidoes on web pages

Hi,
Recently i noticed that firefox stopped playing some vidoes (probably h.264) on webpages (in coursera for example). Before everything was ok and i had no problem at all.
I have installed all codecs according community guidelines since the beginning but then something changed (maybe an update).

Firefox version is 45.0 (with all updates)
Any idea?
Thanks.

Everything normal here with H264, seethis for instance.
Check the format that is not playing, or look for Firefox plugins…

all youtube videos are playable… but for example i cannot play this video http://www.bodybuilding.com/exercises/detail/view/name/bent-over-low-pulley-side-lateral

this helped to fix everything
