Update firefox note in jpegxl.json

[shellheim]

Now jpegxl can be enabled in stable version of firefox also (not only in nightly) so the note should be updated.

Thanks!

@shellheim You told a lie.
No task to link libjxl even in stable builds is not linked to https://bugzilla.mozilla.org/show_bug.cgi?id=1539075.
You must present evidence if you object.
JPEG XL is not enabled in stable builds even now!

[tats-u]

In the first place, you must not overwrite the note for past versions just because of the current one.
You must copy its description and create a new note instead at least.

@tats-u My bad. I saw that the flag image.jxl.enabled was added back in the stable channel. I didn't know that it was not yet functional. I was using a fork and tested on that with the flag enabled and that worked so I made a quick PR. I should have tested on the official browser. Sorry for the trouble.

[shellheim]

are you considering adding that the libjxl hasn't yet been linked in stable but the option is still in about:config in your revert PR (probably as a comment?) for future contributors who see that?

@shellheim

Only links and screenshots are our weapons.

I saw that the flag image.jxl.enabled was added back in the stable channel.

This is a typical pitfall. This does not make any effect in stable builds.

I was using a fork

You should provide more info on that. As far as I know, Waterfox and Pale Moon have supported.

the option is still in about:config

I will cover in that pitfall.

I was using librewolf. They used a patch to fix that and that wasn't in official firefox.

It was done by either of these PRs. They are independent on Firefox HQ, which uses Bugzilla as the bug tracker.
To raise another example, Edge is a Chromium fork but intentionally disables AV1 & AVIF. (This is because I hate Edge)

[shellheim]

Yeah, I knew that. Sorry for the mistake and thanks for taking the time to find the PRs.
