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.

Please add HDR support. I have always seen Firefox as the superior browser and do not want that to change. 💯

Please add HDR. I really want this functionality, which other browsers have.

Really, please add HDR support. I've been using Firefox for almost 20 years and always liked it best but finally, after getting an HDR monitor, this will probably be the one reason making me switch my main browser outside of work.

It's absolutely absurd that HDR support is still lacking, despite countless requests over the years. I switched to Firefox two years ago after being a loyal user for 15 years, specifically because of this issue, and it's still unresolved!

There looks to have been a lot of work on HDR for Linux recently:

Code to add the Linux preference to about:config has just been committed, so maybe it will be available as an experimental feature in 137?

P.S. Thanks to Martin Stránsky who I think is the one working on it.
