When is :has() css selector going to be fully implemented in Firefox?

[stratboy]

I'd like to ask devs when they think :has css selector will be finally fully implemented in firefox. In fact, it's the only browsers blocking this revolution in css authoring.

As posted on 10/24, we came across a few regressions and tweaks we needed to get solutions for. The current goal is to have has() by default as part of the  x121 cycle, and to ride the trains (barring any surprises) to full release. If you have access to Bugzilla, I'd recommend tracking https://bugzilla.mozilla.org/show_bug.cgi?id=1858743 to follow its production release.

Hello @fgriffith 

Thank you for the update. For my understanding; Does this mean this feature will be available in Firefox 121 released at the end of the year?

[fgriffith]

That is the current plan.

x121 Target Dates:

• Beta: 2023-11-20
• Release: 2023-12-19

Hello @fgriffith 

Really glad to see that it's now supported in Firefox on desktop.

Do you have any scheduled date for Firefox Android ?

[fgriffith]

Underlying code is common to android and desktop. It should be available on all platforms on the dates and versions (x121 currently in Beta)  listed above.

Super fantastic! Thank you!!!

Just checked version 120 and dynamic :has test still failing (added by JS element doesn't trigger the selector).

Hello,

Today, update x121 implemented :has selector. But seems that 115.6.0esr doesn't. When firefox esr will implement :has selector ?

Thanks in advance.

As Has() is not a security element, per our ESR release rules, it would NOT be part of an ESR dot release.

"Maintenance of each ESR through point releases is limited to high-risk/high-impact security vulnerabilities, and in rare cases may also include off-schedule releases that address live security vulnerabilities. Backports of any functional enhancements and/or stability fixes are not in scope."

https://support.mozilla.org/en-US/kb/firefox-esr-release-cycle

It should be included in the next full ESR Branch release = 128 July 2024.

Mentioned above dynamic :has test now works in version 121. Thanks!

I wish to thank the mozilla team for their efforts into implementing :has() into firefox.
I have updated to v.121 and it seems to work without any problems.
