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:
Supports from Facebook, Adobe (they're adding export support), Intel and VESA, Krita, The Guardian, libvips, Cloudinary, Shopify
Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.
Given the recent debacle with chrome and choosing to depreciate that codex where we saw multiple large company Representatives including intel, and video, Adobe just to name a few all getting confused and saying we were waiting for this to be supported in browsers with many of them even saying that they already had infrastructure in place just waiting to flip the switch. I think it makes sense and could easily gain Firefox a lot of market share
Jpeg XL support in web browsers will be a great thing for medical imaging!
I personally wait for good lossless compression codec to replace PNG. In this regard JPEG XL is a lot better than AVIF.

Can't wait for widespread JXL support, especially once browsers can handle truncating/resuming downloads automatically so we can stop having to create n number of alternatives for different resolution images and set up media queries to conserve bandwidth. This can, and should just be automated for us. JXL is the only option that does. It's also just replaces everything. The best lossy and lossless compression. Also animation with 24-bit transparency. The only thing it doesn't do better than everyone else is when you way overcompress the image, but like, no one does that, so who cares (sorry avif, I know that's the only thing you're good at). I probably won't use the saliency maps myself, but happy that they exist in JXL for those that will use them.
Again, can't wait for JXL to be officially supported by default in browsers.
Just to put it out there: Affinity products (Affinity Photo and Affinity Designer) also just added JPEG XL support in their V2 update.
Affinity Photo is particularly notable as it is probably the second most popular photo editing tool, second only to Adobe Photoshop.
Other notable software with JPEG XL (JXL) support include FFMPEG, GIMP, Darktable, and ImageMagick.
More software is listed on the Why JXL page.
Here with an exciting update…

There are patches waiting to be merged, that further improve JXL decoding in Firefox. Let's get them merged and working out of the box without having to use Nightly. So far there is no other image format with more potential right now, or even close, which makes it a no-brainer right now. Otherwise I would understand the hesitation. But there is no competition right now. Retrofitted video codecs don't compete with a real image format.
