Quoting reply from upstream - https://bugzilla.mozilla.org/show_bug.cgi?id=1837862#c8:

> The libjxl should only be built on nightly, so anything that is not nightly should be unaffected.

We've updated the list of bundled libraries (which we automatically generate when doing the major Firefox/Thunderbird rebase) to remove libjxl from it. It will be part of the Firefox / Thunderbird 115.x builds.
