It is unable to even start, giving the message of "This addon is not compatible with Firefox", so why even use it when it's "not compatible with Firefox" when it's even uploaded to it's addon store.

Only on reddit.com this extension causes the page to freeze up every time I open a new page. This is only on the firefox extension and it breaks the experience enough that im probably going to be switching my password manager altogether

Figuring out it works only under ShitOS (Windows 10 or later) did cost me an hour of troubleshooting (the extension window was just empty background). Add Linux/UNIX support.

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!

Doesn't work

Displays an error saying “macOS Sonoma (14) or later is required,” but I’m running Sequoia (15.5). A recent update seems to have broken this - it used to work flawlessly.

How about you give a toggle to do passive mode only fill the password when I click the extension icon?
The way it scan the DOM, end up with performance really horrible

Doesn't work on Windows despite description claiming it will work if iCloud for Windows is installed and Passwords is enabled. This is not true, it's just not supported at all.

Stopped working after a recent macOS update. Had worked well up until this point. Currently running 15.4.1.

Edit: Recently tested on 15.5.0 and still no luck

Edit 2: Can confirm this is working now on the latest Tahoe 26 developer beta. Apple has now added the appropriate signatures to allow it to work with Zen Browser.

it sucks so bad. does not work on Zen browser. every time you close and open your browser, you have to authenticate again with a code from apple. there is no autofill, also no password generation

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

It doesn't work in Zen Browser. When it initially asks for you to input the 6-digit code, the Apple popup never shows and asks you to install Sonoma.
