Worked great until macOS 26.4...
Now, the extension prompts the user to save the login even though the login already exists. Honestly, macOS26 has been the best and the worst version ever. Steve would have been infuriated that the user interface is so broken.

It somehow works better on Windows than it does on MacOS, including for the same reasons people are mentioning below (the login popup, or somehow treating random form items like password fields).

The addon has not been updated since December 2025, while the Chrome version has had multiple updates. And that version also seems to address these issues specifically in its updates.

Same as a lot of other reviews. Everything is great except after every login a popup asks for the username to save even though that info is already there. Every login. Annoying to the point that I disabled the extension.

Worked more than fine for a few weeks, now it keeps displaying a message saying: "Enter the username for this account to finish saving your password and allow safari to autofill."

Even though that password had already been saved and this issue was not happening.

very buggy and regularly freezes firefox

I tried to auto fill a 2FA and it wanted to "recommend a password" for my 2FA. Doesn't make sense. Deleted.

Works like a charm, the only problem is the atrocious performance problems it triggers on some sites. Perfect example is translate.google.com

Please fix the performance problems, this extension is a must have for anyone using Apple Passwords as their main password manager, there is no way to circumvent it.

A slow and poorly thought through UX that seems to be more about promoting "Open this page in Safari". If I wanted to use Safari, we wouldn't be here.

why do i gotta enter in my code every single time? it even asks for my code when I'm trying to type something in a search bar

Está bien y tiene potencial de ser muy útil, pero cada vez que vuelvo a abrir el navegador, hay que poner un código. Es muy engorroso...

It constantly asks for a 6-digit verification code. I can't help but feel like this is intentionally annoying to convince people to switch to Safari.

Working on Firefox MAC, but NOT in Firefox WINDOWS.

Honestly this is garbage. For over a year and several versions this Add-on has failed to integrate my iCloud passwords reliably, has broken various websites and Firefox functions, and does a jenky job wither verifications of any sort.

I would think Apple could do better, but I'm not surprised it can't. I've owned MacBook Pros for my last 4 laptops and Apple has lost any focus on the the core functionality. My 'Find My' used to be able to locate a lost phone within ~1 foot. Something must havre changed because I'm lucky if it can trigger an audio ping these days (on that it is batting approx 50% in my unscientific estimate).

So that turned into a bit of a rant, but I'm frustrated. I want my passwords to travel between Firefox and iCloud - this Add-on claims it handles this, yet many, many users report it doesn't work and in fact causes problems. A year of disgruntled reviews and several updates and yet it still doesn't work. Please be more like 'classic' Apple; I am not a fan of 'new' Apple.

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
Edit: Turn off auto fill, it still traverses the whole dom and does its parsing, what's that option even for?

I've noticed that the iCloud Passwords extension is significantly slowing down Firefox, but only on one specific website—Reddit. It would be great if there were an option to disable this extension on a per-site basis, as the performance issue only occurs on that site.

2/5

doesn't work :( it says I need to upgrade >> MacOS Sonoma, but I already have latest Sequoia

With upgrade to Sequoia 15.4.1 on 2017 iMac Pro this extension is bringing firefox to a crawl, slowing keyboard and mouse button clicks, following links and other oddities

Often slows down the sites (eg github). Doesn't always offer saving password when needed (eg mozilla.org). Apple, please, fix that!

Works great until recently it started complaining that it only supports Sonoma and higher, except I just upgraded to Sequoia 15.4
