Description (last modified by Fabian Braun)

As part of ticket-34429 (https://code.djangoproject.com/ticket/34429) JS was added to the password change and user create forms to ensure that the forms run on browsers that do not support the :has() CSS selector.

By now, all major browsers support the selector. The last one not supporting it (Firefox 115 ESR - ​https://support.mozilla.org/en-US/kb/firefox-users-windows-7-8-and-81-moving-extended-support#:~:text=Mozilla%20is%20providing%20critical%20security,supported%20version%20of%20Microsoft%20Windows.) is reaching end-of support in August 2025, i.e. before the next major Django release.

(See discussion here: ​https://github.com/django/django/pull/16942/files#r1427864863)

Steps to solve the issue:

  • Remove admin/js/unusable_password_field.js
  • Update admin/auth/user/chamge_password.html and admin/auth/user/add_form.html to not load the JS file

Based off my understanding, it is reasonable to remove the JavaScript for the 6.0 release

Version: 5.2 → dev

Given that the most recent version to not support the :has() selector is going EOL in August, I think it should be safe to remove this in 6.0.

Updated version to dev, needs implementation.

I'm unsetting the flag because it's showing in the review queue because of it. However, there is no PR linked to this ticket to review.

It's here: ​PR. When in doubt, the beige box above the comments always has hints about taking the next step in Trac.

Fixed #36354 -- Removed JavaScript workaround for browsers lacking :has() CSS support.

This branch removes the JavaScript fallback added in the admin for the
add user and change password templates/flows (Refs #34429).

Django documents suport for "modern, web standards compliant browsers".
See ​https://caniuse.com/css-has for info on browser support per version.
