I cannot play audio or Video on any website I have encountered while I am using Firefox.

[TheRookies5]

While I was using Firefox and trying to play the video, it kept loading and there was no chance for me to play the video online. That happened on certain websites where I cannot play. I know some such as YouTube videos can be played while I am using Firefox, but not all websites have the video playable.

Can anyone know why besides knowing about the new version?

What version of Firefox are you using?

Click on Firefox then About Firefox and in the box will have the version number.

My issue was and still is video/audio buffering when viewing YouTube.

My band width is more than adequate, average 120Mb per sec download,  upload 40Mb per sec, with no issues using Safari.
