Hello.

One laptop has version 57.0 and YouTube HTML5 Video Player works fine with it, the other laptop has version 57.0.1 and YouTube HTML5 Video Player doesn't work with it. Both are Windows 7, 64 bit computers so the operating system is the same, its the version of Firefox that's causing the issue.

I tried all sorts of things from clearing cookies to changing settings and I have researched it and found many are having this issue and what you are suggesting isn't working for them or I.

Is there a way i can move back to version 57.0 on the laptop with issues?

Are you working on an update so YouTube HTML5 Video Player will work with your software?

Take care.

What do you see on the YouTube test page?

Do all boxes have a checkmark?

Hello.

Both laptops with Windows 7/64 Versions have Windows Media Play which is at current version.

The MSE & WebM VP9 is unchecked with a explanation point on the YouTube system.

Everything else is up today with constant Windows Updates.

Thanks
