Firefox Community Forum

I have a Mozilla account. On one laptop, I am logged in automatically when I open Firefox, and can access bookmarks and saved logins. The same is true on my Android phone. But I have a second laptop on which Firefox will not recognize my login credentials. I can log in to Mozilla Support, Monitor, etc., but not the browser itself. When I open Firefox, the login dialog pops up, but when I enter the password, it isn't recognized.

A leak was detected on my account then Mozilla locked it. Every passwords were changed as I still got an "Email just returned" error upon trying to sign in, and now I end up with an "Unexpected error".

And to make sure that this has nothing to do with the plugins I have on my pc installation, I tried signing in on mobile phone as well. Same issue.

I have Firefox 146.01 on 2 windows computers (windows 10 and 11), and on a samsung android phone. I have several extensions (eg uBlock) and I use ExpressVPN.

My mozilla account has a display name and primary email which I verified, and account recovery key enabled. There's no secondary email, no two-step authentication using a third party app. I can readily log the browser back into my mozilla account by entering the password and emailed 6-digit confirmation code, but then it logs me back out within an hour. Each of my 3 devices logs me out repeatedly.

In the address bar I type about:sync-log, and I was able to find the below lines in separate areas of several logs: DEBUG Status.login: success.login => error.login.reason.no_username DEBUG Status.login: error.login.reason.no_username => error.login.reason.no_username ERROR FxA rejecting with error UNVERIFIED_ACCOUNT, details: undefined ERROR Background refresh of initial profile failed: Error: UNVERIFIED_ACCOUNT(resource://gre/modules/FxAccounts.sys.mjs:1669:18) JS Stack trace: _error@FxAccounts.sys.mjs:1669:18 withSessionToken@FxAccounts.sys.mjs:876:18 ERROR Sync encountered a login error DEBUG Exception calling WrappedLock: Error: Login failed: error.login.reason.account(resource://services-sync/service.sys.mjs:1053:15) JS Stack trace: onNotify@service.sys.mjs:1053:15

Based on the above lines, can someone help me figure out why firefox/mozilla keeps signing me out?

Thanks so much

Please can someone be kind enough to assist me. I cannot seem to log in as normal and therefore cannot get my emails and therefore are not able not reply to them.
