Firefox Support Forum

I installed Firefox on a new laptop this morning. When I signed in, Firefox somehow found a very old, like SEVERAL YEARS old, setting of bookmarks, toolbar settings, passwords, etc. and then synced the new device to that old information. Then when I opened Firefox in my other devices, Firefox automatically synced (with the new laptop, apparently) and replaced all my current saved information with all that old information.

I'm crushed. I'm missing several years' worth of bookmarks and other information I'd saved in my Firefox. Is there a way to reclaim the Firefox information I had on my devices prior to signing in on the new laptop?

TL;DR: I ended up with 2FA disabled and recovery key enabled

Hello people !

I'm currently testing Firefox Account features such bookmark syncing and its login security (not password storage/sync). Unfortunately I'm having big trouble authenticating myself to the service right now.

I have 2 testing accounts with the following configuration :

1. I've setup 2FA authentication.
2. I did not set a secondary email.
3. I did not set an account recovery key.

Here are some of the tests I'm doing :

1. I start by doing several login/logout to check if 2FA is working as expected.
2. Then I add a secondary email then make it primary then remove the previous primary email.
3. Then again login/logout several times to check if 2FA is working as expected.

At some point I'm unable to login after some iterations of step 3) above.

1. At first I get an error saying my 2FA code is incorrect. But it allows me to login successfully using one of my 2FA backup.
2. Then again I logout/login several times to check if 2FA is working as it should be.
3. Then at some point I get the same error again saying my 2FA code is incorrect. Trying several unused 2FA backup fails with error saying they're also incorrect.
4. Then it finally says that I've tried too many time and suggests I should retry 15mins later.
5. When I try to login after some time it then ask me for an authorization code sent to my email. But then it says every authorization code I try is also incorrect.
6. I managed to disable 2FA from on one of the account I was still logged in Firefox. But when trying to login on another Firefox profile then I get the same error saying I tried too many times.

Just for clarification - Please note that I may have use one or two 2FA codes instead of authorization keys when it asked me so. But I did not mistyped any 2FA or auth code I've tried.

And after several hours of giving up on it - the problem suddenly vanished and I could login/logout fine. As a precaution I add a recovery key and decided to disable 2FA because I can be sure it will work as is should.

Maybe I get locked but I dont know what really happened. I believe I did not a lot of login abuse though. I just feel like it's a big issue for my case because I could not rely on the 2FA backup and authorization keys. The error didn't help either because it likely says I've been locked. Whereas having one or two mistyped codes or using "several correct 2FA backup and auth keys" which were wrongly considered incorrect - should not be treated as a login abuse or brute force.

From now on I will likely disable 2FA if using this service. I understand these tests are not things you do on everyday use but I can't imagine how bad it would feel if I have sync sensitive data such as passwords and have to wait hours to unlock access to my account (even if not to access those data).

Hello, as of this morning, none of the bookmarks I save on my android phone are syncing across to my PC. When I open my PC, I can see that sync is still working (as all open tabs on my phone are showing as open on the Tabs Pickup screen). I can see that several pages I bookmarked yesterday have saved without issue, so this is something that's happened today. I have my PC set to clear history whenever I close the browser, but I've manually cleared all history and cache. I've also manually synced. I've gone into settings and checked that Bookmarks are still selected as one of the things to Sync.

I have gone to about: sync-log and this is what I see:

Can anyone help? I've been using Firefox for years on my PC, but have only recently started using the Firefox app on my phone and I love the sync feature. Many thanks.

I've logged in on a brand new installation of macOS (Ventura), but it does not sync my logins, passwords, etc. The settings for the sync are also enabled and it works fine on Windows and Linux. Also tried rebooting, but no luck so far.

I have been using Firefox 52.9.0, and I know it is outdated but it still synced until a few days ago at least. Then the other day I updated my password to strengthen security. After that, I am unable to sync anymore. Is there a way to fix it? I need to continue to use Firefox 52.9.0. Please note that I do not need to be told about security issues as I am aware of them well enough.

I get the following message when I try to make Firefox to sync:

> Blocked by Content Security Policy

> This page has a content security policy that prevents it from being loaded in this way.

> Firefox prevented this page from loading in this way because the page has a content security policy > that disallows it.

Thank you.

I inadvertently “signed out” one of my devices so now I cannot see it in my connected services lists. When you sign out a device it states that you will no longer be able to sync or see the device. How do I correct this action so that I can see the device again?

I have a feeling I know the answer, but wanted to confirm. Due to unforeseen circumstances, I had to reset my PC. Upon doing that and downloading Firefox all of my data is gone. Bookmarks, saved logins, etc. all gone. I thought once I logged into my Firefox account everything would be there. I've logged into my account on other computers in the past and all my stuff was there but not this time. Now it's saying all of my stuff (profiles, etc) was created today. Is my stuff really gone forever? I thought the whole point of the Firefox account was so I could just login and have everything sync.

Hello, I have a set of passwords on Firefox mobile (iOS 16.3.1 and Mozilla Firefox 110.1 (28420)) that I am trying to sync with my desktop version of Firefox, however, none of the

The logs on desktop in "about:sync-log" show "error-sync-1679324467306.txt"

I believe I have tried absolutely everything there is to try in the help articles and forum here. Both devices are indeed signed into the same account.

Thanks for any assistance.

Every time I connect my account on another device to sync up, it totally resets extensions and new tab shortcuts on ALL of my devices. It keeps my bookmarks, theme and what extensions are installed, but again all of my new tab shortcuts and my extension are reset, which is a pain in the rear for extensions like NoScript and taking the time to rebuild all of the new tab shortcuts.

Is there any way to set a device as the primary to push out to others or download those settings to avoid having to set them up again?
