As described in the title, any form of video playback on any website will randomly dim almost like autobrightness for video playback. This has nothing to do with auto brightness etc because I have this turned off in my device settings as well as the only affected region of my screen being the part that is playing video. This does not happen on any other browser.

tldr when using firefox something keeps dimming my video and i don't know how to turn it off.

Did you makes sure to uncheck DRM settings in Firefox to see if that isn't causing the issue as well?

Then what is the video site? There has to be a site so others can compare to insure it's not a Browser or Addon or something causing the issue of video playback.

Check your graphics card driver software for any video-related color features. These settings do not affect all applications the same.
