    With both Firefox and Chromium using jxl-rs (Rust-based), I wonder what Apple will do about the libjxl (C++) they already shipped. I know they're doing some memory-safety with Swift, but are they shipping any Rust in their platforms so far? I also wonder if anyone's done benchmark comparisons between both libs.--Also, I was under the impression that after backtracking, Chromium was relying on Mozilla to come up with a Rust port, but it seems it was the reverse. Good on Google Research.https://hacks.mozilla.org/2026/08/intent-to-ship-jpeg-xl/> So, we laid down a challenge to the JPEG XL team at Google Research: Build a safe, performant, compact, and compatible JPEG XL decoder in Rust, and we’ll ship it. That challenge was met; Google Research built jxl-rs, and it’s the core of our JPEG XL support in Firefox.

    Now I'd only wish browsers could come up with more convenient ways to get around when some websites and upload fields don't support jxl or some other image format, and would either do something about it automatically or offer some option to get around it (convert to jpeg or png and upload, or 'paste as an image' which would pretty much be the same as png conversion, or something)

    Will they add it to Firefox 115 for the remaining Windows 7/8 users or will you need a new operating system to add an image format?

    I'm curious how many HN people in 2026 have not yet heard of JPEG XL / jxl
