All videos on Facebook and you tube are purple and green and not in sinc with each other. This is definitely a Firefox problem as I tried both on Chrome and they worked fine. I prefer Firefox, but if it isn't fixed I will be forced to move over to Chrome. Hope this can be fixed.

hi, we are currently aware about this on some windows 8 configurations with amd graphics cards and older drivers. please see if there's a more recent graphics driver available for your system at https://support.amd.com/en-us/download and if installing that already solves the playback issue.
otherwise you can do the following to work around the problem: enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named media.windows-media-foundation.use-nv12-format. double-click it and change its value to false.
