HDR support for Windows

[LinDen]

Firefox managed to bring HDR to Macs in 100.0 version. Now it's time for Windows!

It'd be awesome to watch and work on HDR images and videos using Firefox in 2022. Windows is the most popular OS, why not bring HDR here too?
More monitors and devices running on Windows support HDR, so there is an increase in demand of HDR support in Firefox.

The only option for Windows users is either to switch to another browser or to download and use a dedicated app from Microsoft Store.

Almost a new year, and now we are on version 146. 

So 3 years down since this idea was created and 46 Firefox updates, and still nothing. 
BUT HEY WE HAVE AI ENHANCED TAB GROUPING NOW!! yayy.....

The date this thread was created was: May 18, 2022. 
Firefox 100 was the current version at that time. We are now at Firefox 146.
46 major updates in 3 and a half years.

No updates on HDR for windows. 
BUT HEY WE HAVE AI ENHANCED TAB GROUPS NOW! yayy........

How much more resource hogging LLM garbage will I have to disable before they add an actually useful and requested feature to the browser?
Who can say!

Windows 11 now seems much better with HDR, so I am not at a point where I leave it on all the time and Firefox is now an outlier in it's support - can we get an update please?

Oled HDR displays got really affordable in last year. I am really amazed that Firefox does not support HDR. I believed that it is industry standard with every bigger movie or game coming with HDR. I Guess there is some major technical problem with enabling HDR playback in firefox. Sad.

@Jon Any updates? It's awfully close to "end of year," and your CEO seems dead set on wasting time cramming LLM crap into the browser rather than putting devs on actual features like this one.

Will there be a Christmas miracle or is the wait for HDR going to drag into 2026?

Soon find out!

So are we getting any proper HDR support on Windows? OLED monitors with good HDR features are becoming much more affordable now, specially as we begin 2026, there are so many good deals for OLED monitors. Chromium has HDR support for so long now yet Firefox is still falling behind on this area, cmon now.

As an new OLED monitor user myself, it sucks that I have to use another browser like Edge (that still has Ublock Origin support btw so far) when I want to watch videos on Youtube that have HDR support, it was said it would be looked into, being implemented during 2025, so far nothing. Guess shoving AI is that more important now than this huh?

Starting with Firefox 148, HDR video on Windows is now supported in Nightly builds. This is considered experimental as we gather feedback before enabling it in regular releases. This feature works best when HDR mode is enabled in Display Settings (this may require a page refresh); otherwise, the display driver is likely to apply a tonemapping effect for non-HDR viewing. Some streaming sites may still not offer HDR video in Firefox.

Working perfectly, thank you team!

Hi folks!

Thank you all for your patience - I know that it's been some time since we said that HDR support on Windows is under development. Starting off with good news: HDR video support is now enabled in Firefox Nightly 148. (We're also working on support for Wayland on Linux.)

We're going to use this time to gather your feedback on what works and what doesn't across varied hardware in the wild before we inevitably launch it to ALL Firefox users. We're getting there, we promise!

If you'd like to keep track of the remaining work, please refer to this meta bug. This is also the bug to link to if you'd like to report and file a bug as you play with our HDR support.

Some notes:

• Please note that this is HDR video support. HDR images is a separate (and much, much larger) piece of work on our roadmap.
• To get the full experience, you will need an HDR display, and the HDR feature needs to be turned on in Windows (Settings -> Display Settings) for that display.
• This release also changes how HDR video looks on non-HDR displays in some cases: this used to look very washed out, but it should be improved now. Feedback on whether this is a genuine improvement is also welcome.
• Popular streaming websites may be checking for this HDR capability, so they may now offer HDR video content to you, but only if HDR is enabled on the display.
