Firefox 技術支援討論區

On a laptop running Windows 11, all videos I play in Firefox have been strangely dark and orange. Depending on their original appearance, this can make them unwatchable.

This only affects videos in Firefox, and only on this laptop. Chrome, Windows video player (and Firefox on my other devices) do not share this issue. The issue affects all monitors I connect the laptop to.

I have attempted: -A thorough search of Firefox settings and found nothing related. -Refresh and reinstall of Firefox -in about:config

   gfx.color_management.native_srgb to true
   Confirmed ui.videoDynamicRange was set to to 0

None of these has helped. According to all the evidence I can find online, a similar issue was caused by a problem with HDR video files and fixed in an update 2 years ago, but I am running version 127.0 and am up to date.

I am a long-time Firefox for Mac user and recently, browser APP all of a sudden is ignoring selected PRINT preferences. Two examples are: Printing one-sided when two-sided is selected, and printing in color when the default and selected preference is for a "Black and White Fast Draft". I use a MacMini M1 running Sonoma v14.5 and Firefox v 127.0 (64 bit). My printer is an HP OfficeJet Pro 8710 with up-to-date firmware. I have resorted to use of Chrome until I resolve this situation, though I prefer to use Firefox. In addition, while it may be a separate issue, I also found that the use of Firefox when using GMAIL developed a new issue at approximately the same time. Now, when clicking on the selection box for an individual email, Firefox often does not allow the box to be checked, but again with Chrome, it works just fine. Any help would be appreciated. Thank you.
