Videos on YouTube, Facebook, Vimeo etc are played back with magenta colour shift and lower luma levels (less bright) compared to the original video, or the same videos as viewed on Safari, Chrome, etc.

Is this possible to fix, as produce video content for a living, and it is very difficult to make colours look good when Firefox changes them.


Your help is greatly appreciated

Here is a picture with the changed colours. It only apperas when runningFirefox in 64 mode.

The system is an Win 10 64 bit, running on a AMD A6-3650. Firefox ist installed new without any add-ons, except those that come with firefox.

Within in the same installation a firefox 32 bit runs fine. Firefox 32 bit and 64 bit are installed parallel. Single (clean) install does not improve the situtation.

Seems to be fixed in the Firefox 64bit Version 55.0.3
