HDR videos (specifically smpte2084 (PQ) / bt2020 videos) on youtube don't show correctly since last few updates of firefox on mac M1 & M2 sonoma 14.5. Firefox shows overly bright (almost whitewashed) videos, seems like something changed either with MacOS or firefox in last few updates. Firefox was working fine on older MacOS last 2 years with HDR videos.

Here is a link to test this problem on Mac, Safari shows the same video correctly in HDR https://www.youtube.com/watch?v=s52wB4lKLeo

Kindly fix this problem soon.
