Support JPEG XL

[chi]

I think it's a great opportunity for Firefox to stand out by supporting JPEG XL before any other browser.

Imagine images served by Cloudflare and Cloudinary load faster and look better only with Firefox. Firefox was a pioneer of web technologies and it should win the title back, if Firefox just keep following Chrome without any differentiation, why would people choose Firefox?

If the decoder memory safety is a concern, maybe Mozilla can start a crowd funding campaign to sponsor a Rust decoder, even the campaign itself will attract reports and attentions for Firefox.

Mozilla argued AVIF was already supported as a same generation but clearly JPEG XL has many advantages:

• Much better encoding performance (AVIF is not suitable for realtime CDN optimization at all)
• lossless and better high fidelity (video codec based image format)
• HDR (there will be a billion of mobile devices with real good & bright screen in just a few years)
• Little generation loss (important for web)

Supports from Facebook, Adobe (they're adding export support), Intel and VESA, Krita, The Guardian, libvips, Cloudinary, Shopify

I would love to see Firefox supporting JPEG XL as the first Linux browser!

[Archprogrammer]

That's too late I believe - at least both the Palemoon and Thorium browsers already support JPEG-XL. Firefox could be the first major browser to support JPEG-XL om Linux, which would be really nice.

JPEG XL is also at the top of Interop 2024 reactions (505 votes vs 136 for 2nd, 91 for 3rd): https://foolip.github.io/interop-reactions/

Sadly Firefox stays behind: https://webkit.org/blog/14633/get-ready-for-interop-2024/

JPEG XL is definitely at the top of Interop 2024 (with 536 reaction while the next are: 136, 92, 78):

Does it mean Firefox will finally adapt it in 2024?

Samsung has just started supporting JPEG XL: https://r2.community.samsung.com/t5/CamCyclopedia/Introducing-the-Galaxy-S24-Camera-Gallery/ba-p/153...

When will we be able to see such images in Firefox?

[cmscy]

@Jarek  never, use floorp by ablaze or waterfox

I can't understand why Firefox can't be the leader about implementing JXL yet. Safari does it.

[Dasein]

Please! JPEG-XL has benefits from many other formats (and advantages over WebP/AVIF) including animation & lossless option, Filesizes can be scaled up and down according to use-case,

and it has an all-in-one approach that's backwards compatible with legacy formats, surely Firefox would seize this opportunity to show why other companies should seriously move towards more open-standards.

Also why they should consider moving away from their locked-down proprietary ones that they get an advantage in pushing due to their market position? I believe that this format would be in-line with Mozilla's stance on browsers in general and offers the users choice.

@RafaelLinuxYeah i agree. It doesn't make much sense why Mozilla isn't being a leader on this. I think we just need to get more support on this thread to get further eyes

 @Jon it has been a bit over 6 months since the last update on this. Is there any internal discussions regarding this?

[Sandstrom]

Would be great if JPEG-XL support was added.

As a business with terabytes of images, JPEG-XL brings many benefits (performance, quality, image sizes, among others).

I think it’s clear at this point that there is strong demand for this format. Make 2024 the year when Firefox adds support.

Interop 2024 rejected JPEG XL.

This doesn't mean Mozilla will never implement JPEG XL but considering Mozilla's most revenue is from Google... 🙊

[Jarek]

After Adobe and Apple, now Samsung starts supporting JPEG XL ( https://cloudinary.com/blog/samsung-now-supports-dng-1-7-including-jpeg-xl ), seems like Windows will soon ( https://old.reddit.com/r/jpegxl/comments/1adayiq/jpeg_xl_found_in_wincodech_suggesting_coming/ ).

What condition is Firefox waiting for?

[RafaelLinux]

Chi, I was totally unaware of that. That may explain it perfectly.

Hi @Jon - Any update on if / when you'll enable JXL?  JXL's priority on fidelity over avif, webp and heic stronger focus on appeal make it well worth enabling. 

Given you've done the work of implementing JXL in Firefox and Apple's Safari has enabled it, what's holding you back?
