My meetings link isn't working in Firefox.

When using automatic proxy settings in Firefox on Windows 11, the meeting link does not work.
I have found that if I specify a PAC file in the manual settings, there is no problem.
I know that this can be worked around manually, but this makes the automatic settings meaningless, so is there anything I can do about it?
I don't know if this is a Firefox problem or a Zoom problem.
I have confirmed that there are no problems with Chrome and Edge.
