Syncing between my desktop and my phone has been working just fine for years, just as it had been with my laptop until recently, but I changed the version of Linux I had installed on my laptop earlier today, and despite being able to sign in just fine (as you can see by me posting this with my account), and it syncing correctly on the initial sign in, actively syncing between my laptop and other devices is not functioning (if I make a new bookmark right now, it ''will not'' show up on my phone or desktop). Looking at the sync page in settings it says "Please sign in to reconnect [my email address]", and the account widget on my toolbar has a yellow triangle symbol and a warning saying "account disconnected", but if I click "connect to another device" on the sync menu and then click "not now" I can get to my account page, fully signed in and able to click buttons to change settings (I signed out my old laptop while I was there just fine). Attempting to re-sign in by any method (clicking "connect to another device" in the sync menu and then choosing "I already have Firefox mobile"; clicking "sign in" in the sync menu; signing out fully, emptying my cookies etc. and then signing in fresh) all leads me into a loop where I insert my password, provide a verification code from my email, provide my 2-factor code, click "I already have Firefox mobile", and then have to sign in again doing the same steps leading to the same place, forever. I will note, however, that signing out entirely and then signing back in does get me from signed out to signed in despite not correcting this error. In case it would help I attempted to change my password via the account menu, but it says that my ''definitely correct'' password (I used the exact same entry from my clipboard successfully to sign in moments ago) is incorrect, and attempting to use the "forgot my password" menu gives me the error "Unexpected error" instead of doing anything, which is not very helpful. My password remains unchanged. I do not know if this is relevant. After some looking things up I was made aware of a secret menu called "about:sync-log" which I used to see if I could find an error message, and I did indeed find one (I can guarantee that it's new and relevant because this Linux install is only several hours old). I don't know how much of this error log is safe to share, so I'll only cut in some choice segments I noticed (which turned out to be, like, over a third of it): 1729711964409 Sync.Status DEBUG Status.login: error.login.reason.no_username => error.login.reason.no_username [...] <- (I will use this to indicate I've scrolled further down the log; any further edits to the logs will be ##surrounded like so##, for the purpose of visibility) 1729711964819 Sync.Status DEBUG Status.login: error.login.reason.no_username => error.login.reason.no_username [...] 1729712030365 FirefoxAccounts DEBUG FxAccountsWebChannel message received: fxaccounts:login 1729712030366 FirefoxAccounts DEBUG Webchannel is logging a user in. 1729712030368 FirefoxAccounts DEBUG setSignedInUser - aborting any existing flows 1729712030368 FirefoxAccounts DEBUG removing account data 1729712030369 FirefoxAccounts TRACE starting write of json user data: null 1729712030425 FirefoxAccounts TRACE finished write of json user data - took: 56 1729712030426 FirefoxAccounts TRACE storage set finished clearing account data 1729712030426 FirefoxAccounts DEBUG account data reset 1729712030426 FirefoxAccounts TRACE StorageManager finalizing 1729712030426 FirefoxAccounts TRACE StorageManager finalized 1729712030427 FirefoxAccounts TRACE initializing new storage manager 1729712030427 FirefoxAccounts DEBUG writing plain storage: ["email","sessionToken","uid","verified"] 1729712030427 FirefoxAccounts TRACE starting write of json user data: ["email","sessionToken","uid","verified"] 1729712030454 FirefoxAccounts TRACE finished write of json user data - took: 27 1729712030455 FirefoxAccounts DEBUG writing secure storage: ["keyFetchToken"] 1729712030455 FirefoxAccounts TRACE starting write of user data to the login manager 1729712030467 FirefoxAccounts TRACE finished write of user data to the login manager 1729712030467 FirefoxAccounts TRACE initializing of new storage manager done 1729712030467 FirefoxAccounts DEBUG Notifying observers of fxaccounts:onlogin 1729712030468 Sync.SyncAuthManager DEBUG observed fxaccounts:onlogin 1729712030468 Sync.SyncAuthManager INFO Sync is not configured, so ignoring the notification [...] (skipping further now.
