Checking the Firefox bugs on this, it seems they decided to replace the C++ libjxl with a rust version which is a WIP, to address security concerns with the implementation. All this started a few months ago.

Maybe the zen fork is a bit older and still using the C++ one?

... update. after reading the comments in the rust migration security bug, I saw they mentioned "only building in nightly for now"

I grabbed the nightly firefox, flipped the jxl switch, and it does indeed render fine, so I guess the rust implementation is functioning, just not enabled in stable.

... also, I see no evidence that it was ever enabled in the stable builds, even for the C++ version, so I'm guessing Zen just turned it on. Which... is fine, but maybe not very cautious.

Do you have any proof/more about this? I've never heard this claim and I'd like to know more

1. Zen Browser had remote debugging enabled by default and disabled the security prompt for it. Extreme incompetence or malice? https://github.com/zen-browser/desktop/pull/927

2. Social trackers are selectively allowed, unsigned extensions are enabled by default, and Enhanced Tracking Protection isn't fully implemented.

There's just a theme of incompetence, trying to cover it up and just in general being clueless about security.

good. image parsing has produced so many bad RCEs.

Google Chrome is using a Rust implementation. The existence and sufficient maturity of it is the reason they were willing to merge support in the first place.

Hmmm, check the jxl-rs repository. I wouldn’t call it mature. Not to say it’s buggy, but most of its code is very fresh.
