After the most recent update, my desktop version of Firefox keeps disconnection Sync so my passwords disappear. I also have an iPhone Firefox app doing Sync. The passwords reappear when I reconnect Sync on the workstation, but I want the desktop workstation to be the master and the passwords to always be available. How do fix it?

When I'm trying to login to Sync my Firefox account, I'm getting a cors error after putting in my email address and clicking the sign in button. This is on a new profile with no extensions installed on 150.0

Im trying to sync my android to existing account on PC. Phone says my firefox login incorrect yet when I go to firefox settings , it shows my name and password that I used to try to log in with phone. I then tried the scan option, but when I phone up to pc screen to QR code, it just sits there. SO I think ill just change my password. I go to password change section and it sends me the code via email. I input the code and brings me to change password screen yet when i try to change it, it states the prepopulated old password is incorrect. I am logged into PC with this info so how is it incorrect?

I have two computers that I use and I have them setup the same. Both have Windows 11, both are the same model, HP. One computer has 260 passwords and the other has 253 passwords. Why aren't they the same. Same sign in name Ronald Cogan, same email, same password. But when I bring up the one computer it shows 260 passwords and when I move over to the other computer it show 260

Добрый день. У меня всё было хорошо, и ранее с телефона всегда были доступны синхронизированные вкладки, которые открыты в браузере на ПК, однако недавно мне понадобилось разлогиниться на телефоне, потом я снова залогинилась, и с тех пор у меня возникла с ними проблема. Вкладки просто пропадают сами по себе спустя время. Чтобы они снова появились, мне нужно оказаться у своего домашнего компьютера и открыть Firefox, и осуществить синхронизацию (если она не успела произойти автоматически). Тогда какое-то время эти вкладки появляются в Firefox на моём телефоне с Android,.. а спустя время снова пропадают. Это очень неудобно, потому что я не могу, находясь на работе или в поездке, комфортно воспользоваться вкладкой, использованной на домашнем компьютере. Раньше эти вкладки были доступны всегда, и я всегда была спокойна и уверена, что могу к ним обратиться. Что делать? Помогите, пожалуйста. Прикрепляю скриншот, где видно, что вкладок нет (к сожалению, сейчас не могу сделать скриншот, где они есть, поскольку в данный момент времени я нахожусь на работе).

I am trying to use Firefox passwords on on Windows 11 and iPhone via Sync but password changes made in Windows 11 do not sync to the iPhone unless the sync is triggered manually from within the Firefox for iOS app. Password changes do not sync automatically.

Windows 11 v149.0.2 Firefox for iOS v 150.0

I've exported my bookmarks as an HTML file on my old computer (Win 11 Firefox ver 149.0.2) using a USB drive and tried to upload the file to my new computer (Win 11 Firefox Ver 149.0.2.). Only a few dozen of hundreds of bookmarks transferred. Repeated tries simply add the same bookmarks to the menu.

I've tried sync. Both computers are signed in and are correctly listed in the connected services box. Syncing is ON and when I select the Sync Now button on either computer screen, the Sync Now switches very briefly to Syncing and then back to Sync Now. Sync has transferred no data from my old computer to my new computer.

Any ideas are welcomed. Thanks, Jagwriter

I'm signed in on both the mobile and desktop app with the same account, sync is on for both of these, but the sync is not actually happening. None of my passwords or history is accessible in the mobile app. It also seems to not save any history at all because I keep having to type in whole web addresses instead of the app filling in the rest itself, even though I've visited these websites many times. There's no error in the settings or anything, it's just not working properly.

Recently, for some reason, my Send to Device on mobile doesn't send the tab to Desktop. I'm running the latest Firefox on PC and mobile (Galaxy S25+ latest Android version).

I've tried uninstalling/reinstalling mobile, logging out/reconnecting my Firefox account on PC and rebooting but nothing seems to work. I CAN send from PC to mobile device; just not the other way around. Started maybe a month or so ago without warning.

Dear All, I recently reinstalled Windows and updated to the latest Firefox. When I tried to sign in to sync/restore my bookmarks, Firefox could not recognize my password. I reset it and used the new password, but the bookmarks that appeared were outdated, and not all information synced to my current account.Could you please advise on the steps (or a quick solution) to fix this?Many thanks for your support in advance.Kind regards, Tareq Zeyad

i have synced everything and 3 days ago when i restarted my pc and launched firefox everything was deleted and i had to login to my account and firefox saw it as a new pc today it hapenned again after pc restart and i have like 4 same pc with open cards and i cant back them back i have to launch everything by hand and i dont want it to happen again had no problem for 4 years of using

I've been a Firefox user for ~15 years or so and specifically a Nightly user for about 10 of those. On my Samsung Galaxy S24+ I recently had to reinstall the Nightly app; However, when I logged in and confirmed my identity to Mozilla™ it appears to have synced everything EXCEPT my bookmarks. Luckily I had the standard Firefox Browser for Android app also installed on the same device so not all is lost.

My Question: What could cause Nightly to sync other things but exclude bookmarks? Is there a way to export the ones from the other Firefox version to a file, then import them to Nightly?

Any Help Would Be Greatly Appreciated! Thanks In Advance :-)

Well, I don't know how I did it, but:

I'm trying to sync my Firefox between 2 PCs. I had trouble with it, and now the situation is: a) my source PC asks me to create a new profile as it spits the dummy on my existing one; it does not offer me the option of creating a new account b) my destination PC does the same. In both cases, when I choose the "Sync and save data" menu option, then enter my email, I get the message: "This profile was previously synced to a different account. To keep your data...To sign in using <email address>, create a new profile." Creating a new profile does not have all the configuration and info that I have in my current profile.

It would be nice if I could reset everything back to square one with the sync process. Does anyone have a good suggestion?

Paul.

On IOS, for the last few days, the syncing of my profile has been failing, because of a timeout.

I have gone so far as to delete my many year-old Firefox Sync profile and rebuild it from scratch, reconnecting various machines. I have also carefully examined said profile, bookmarks, etc. I am unsure of what the timeout issue is, and whether it can be addressed, or of whether my particular use-case is no longer suitable (over the last few days) from Firefox Sync, which is one key reason I've been using Firefox more or less since inception.

Any advice, or is there a bug in the Sync back or front-end?

The relevant log lines are, I think:
