icloud sign in fails with firefox: "Failed to verify your identity. Try again."
Hi, I'm using Firefox 142 on Ubuntu 24.04. It's a fresh install. I cannot sign in icloud.com with Firefox even though it works with other browsers like Brave. I deleted all cookies and site data and disabled extensions (KeePassXC). It doesn't help. I tried in new private window. No success. I copy my password from a password manager, so, no, I haven't mistyped it.
Here's what I do:
- Open Firefox and go to icloud.com
- Click on the "Sign In" button
- Enter my Apple-ID and click on the arrow on the right end of the "Email or Phone Number" field
At this point Brave behaves differently than Firefox. See below for how Brave behaves.
Firefox: -> A "Password" field appears (no buttons "Continue with Password" and "Sign in with Passkey")
- Enter my password and click on the arrow on the right end of the "Password" field
-> Error message "Failed to verify your identity. Try again" appears. See icloud.png
Brave: -> Two buttons "Continue with Password" and "Sign in with Passkey" appear. See icloud-with-brave.png
- Click on button "Continue with Password"
-> A "Password" field appears.
- Enter my password and click on the arrow on the right end of the "Password" field
-> 2FA code is sent to my iPhone -> "Two-Factor Authentication" form opens... etc. complete sign in successfully
Please help!
Unfortunately I cannot attach the HAR file from the login sequence because the password is included. However, I attached some screenshots from the Web Developer Tools. It seems to me that the login flow with Firefox is broken. I can't tell who's to blame, Apple of Firefox. The error message with Firefox is always the same, no matter whether I enter the correct password or rubbish. In Brave, however, there is a more precise error message when I enter a bad password.

Interesting.... Seeing a few more post with the same issue. I have no issues with it. see screenshot Try downloading Firefox from Mozilla. Download, unzip, and run firefox-bin from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release
What happens under a different user account?
Hi there,
Please know that our team is looking closely into this. It's currently the top priority for our Web Compatibility team. We appreciate your patience we we work on an update.
There are several issues currently being looked at with Apple.
In case your Firefox comes from Snap store, there's a known issue at iCloud side at the moment, and just installing a version from Firefox.com directly solves it (or, leaving out the "Ubuntu" part of the user agent string via about:config or an add-on also works around the issue).
If your user agent doesn't contain "Ubuntu" and you still can't log in, there's an issue with older profile data causing conflicts with their authentication that can be easily resolved: a private browsing window or clearing site data should allow you to log back in again.
Hi,
The latter issue should now be resolved. Could you please try signing in again to confirm (or not) the fix?
(Judging from the attached screen shots the app comes from Snap distribution, so this one is still tracked in: https://bugzilla.mozilla.org/show_bug.cgi?id=1983681 …)
I had this problem yesterday. I did "Refresh Firefox" and was able to log in to iCloud. Then I logged in to everything else over the course of a day, and then got a Software Update to
firefox 143.0.3-1 6933 latest/stable mozilla✓
Then I tried logging in to iCloud, and got the same problem "Failed to verify your identity. Try again." It doesn't get to the point of attempting 2FA.
In a bar at the top of the client area on another web site, I got a dialog message from Firefox (sorry I didn't copy down the text exactly) "Firefox now does DNS requests securely for every (something or other). I tried "Disable" a button it offered. After that, it was able to log in to iCloud.
