It just works.
Windows 11 24H2.
Firefox 142.0.1.

Work perfectly for me, it also fill OTP tokens if have them on Apple Passwords.

FINALLY this works with Firefox for Windows! I was able to autofill passwords as well as verification codes. That was primarily what was keeping me on MS Edge (well, that and the actually functional sidebar), so thank you.

Thank you Apple and Firefox for bringing this extension back to life! iCloud Passwords hadn’t worked on Firefox for several versions, and I had to switch to Safari. Today I randomly gave it another try—and it works! So happy to be back. Firefox, home sweet home!

It just works perfectly. 0 Problems so far. Really glad i found it - basically using it daily (dev).
