Firefox Community Forum

According to this support page (https://support.mozilla.org/en-US/kb/sync-custom-preferences#), setting ``services.sync.prefs.dangerously_allow_arbitrary`` to True will sync all my preferences.

I have set it to true on the two devices I want to sync (2 desktops, Windows and Ubuntu). However, the preferences are not synced. For example, ``browser.compactmode.show`` keeps its default value "False" on my Ubuntu installation, despite it having the modified value "True" on my Windows installation.

I have tried pressing "Sync now", and restarting the browsers - to no avail.

Could anyone tell me what am I doing wrong?

I have Firefox Sync enabled in my Firefox browser on a few computers. When I logged in to Firefox Sync initially, it did sync-up my new computer with all of the saved bookmarks and history. I am not sure if any of my logins were saved). When I go to websites and login, I am prompted with the dialog to save my credentials, and I say ok, save. But the logins are not remembered. And in my about:logins page shows "no logins found". I don't care about retrieving any old logins, I just want to be able to save new ones and get the default behavior of saving logins working again.

When I scan the QR code shown on my computer with my phone and press the sync buttons, I get a message on my phone to; "Open the authentication app and enter the security code it provides."

I have no idea what this app is or where to find it to open it. Is it on my phone or my computer? Why can't you just show the code on my computer sync screen?

And, your help pages just repeat the same instruction verbiage as the sync app on my phone. No additional help at all!

I formatted my computer and logged into firefox, but all of my things are gone. No bookmarks or anything. I've never had this problem before when formatting, so I'm hoping it's still somewhere? Thanks in advance

Dear help team,

First of all, thank you for your efforts to help this community. I've been using Firefox for about a decade and this is my first question, I believe.

I recently got a new Macbook. I've installed Firefox to it (my primary browser) and want to sync Firefox to it. I have Firefox on my iMac and my iPhone. However, my password is from 2014 and I can't seem to remember it no matter how many times I try. If I choose a new password, it gives me a warning that I will lose my account information, including my bookmarks, add-ons, history, etc. I really don't want to lose that info! I have spent a long time personalizing my Firefox.

Pleeeease tell me there's some other way to sync Firefox to my new laptop (when I can't remember my super old password).

Thanks in advance for your help! Best, Jason

I can sync my home desktop (Windows 10), home tablet (Windows 11), and phone (Android) just fine, but I am having trouble syncing with my work desktop (Windows 10). As I can work from home, I would like to keep my bookmarks, history, etc. synced.

While at work, when I start Firefox, it says that I am running an older version of Firefox and either need to create a new profile or exit to avoid problems. So I create a new profile, then update to 117, then restart Firefox, and things are fine for a bit. Eventually though, if I exit Firefox, it will go through this cycle again the next time I start Firefox. When I check the version after starting, it says that I am on version 115, even though I already updated to 117. I went into about:profiles I saw that there were several profiles there: default, default-release, then default-release-1, 2, etc., with the most recent number being the one currently in use.

Could this be some sort of organizational setting that is preventing the update from sticking? Is 117 not 'backwards compatible' with 115, so to speak, with regards to syncing? Any way to work around this? Any insights here would be appreciated.

Hi. I have problem with firefox account addon. I acidenty remove it from the addon menu(that one on the right up corner in firefox) and i can't find it in addons setings. how can i add it again to addon menu?

Recently I activated 2FA on Firefox. I scanned the barcode by Google authenticator, to make it my code generator.

I'm now trying to enter Firefox on my laptop. After typing my password, when I try to enter one of the generated Google Authenticator codes, I constantly get a response "Invalid code".

I had to use one of the backup codes (out of the 8), and managed to enter my account on the laptop, but none of the logins and passwords were found there (it's empty).

My first question is why does Firefox reject the codes received from Google Authenticator (do I have to cancel my 2FA and define it once again? but I did everything by the book, with GA, and it seemed fine the other day).

My second question: I finally managed to enter my account with one of the eight backup code. Why are there no passwords etc? Aren't they automatically drawn from my usual (existing) account?

The laptop runs Win 10. I installed the 2FA on my main computer, which runs Win 11.

Thank you very much in advance, Eldad

Although I have disabled all relevant "sync" settings in Firefox, the browser is still syncing tabs across my MacBookAir and my iMac.

To make matters worse, tabs in Chrome and Safari sync to Firefox tabs across devices as well. The sync occurs in both directions.

I am not logged into Chrome or my gmail account.

Specs: MacBookAir: early 2015/ OS v. 12.7 (Monterey) iMac: Retina 4K, 21.5-inch, 2017 / OS 12.6.8 (Monterey)

Things I've tried:

• Turning off syncing in Firefox on both devices.
• Signing out of Firefox from both devices.
• Disabling "sync open tabs" via Firefox preferences
• Renaming devices from within Firefox Sync. (The name always reverts to the previous one.)
• Reinstalling Firefox
• Deleting cache from both Firefox and Chrome.
• Restarting

Images are from toolbar on iMac when Firefox is open on both computers. Any help would be most appreciated! Thanks!

XP FF68esr needed upgrade, wont sync, blue snake chasing tail. Installed Linux and FF78 (dual boot) on same machine. Deleted key4 cert9 and places carried over key3 cert8 and logins from xp68 and got everything back in order and working, except for sync. I was running FF79 on my Firestick and login to my FF account I could see the Linux machine but no sync between the two. I just installed FF120 Nightly on the Firestick to try to get used to it, but it wont sync to the Linux. It did sync to the FF79 on the Firestick however.

My windows got corrupted had to reinstall everything and this means i have lost my old Firefox account password is there anyway i can get all those saved passwords as i need them. Any help would be great

my computer broke about 2 months back and i am wondering if i can access the tabs from that device from another device since the original was synced (or i.e. is the a function in Firefox that lets me see all synced tabs from all connected devices)

going to the regular synced tab area there isn't anything from that computer there,

Firefox v.99.0

I see instructions for sync' to a phone, how do I initially (connect) sync to my desktop from my laptop?

When I sync my bookmarks, how does is know which computer is the primary (the one that I want to duplicate changes from)?

For example, I added new bookmarks and revised some old ones on my laptop and did not have the sync on my desktop at the same time. Now, if I sync my laptop to my desktop, how does it know which device is my primary (in this case my laptop) where I made all the changes?

My goal is to revise all the bookmarks currently on my desktop to reflect all the changes I made to them on my laptop. I'd like to do it without duplicates or displaying old desktop residual bookmarks that I deleted and/or modified on the laptop prior to sync to the desktop.

In this case, should I delete my bookmarks from my desktop and then sync to my laptop so as to seamlessly & efficiently have my bookmarks toolbar on the laptop look the same on the desktop?

Thank you for your help here! Christopher

Hello, I was reinstalling my OS, and I didn't create recovery code for my data to retrieve it after (which I found out after reinstalling my OS) on my Mozilla Firefox account, I had a lot of passwords, bookmarks and data that I need to recover, also for my full time job a lot of valuable data which I have lost now. I couldn't find any email address so I can address my concern directly, It's why I am posting here. Please help, I am so lost now. I can also provide you with any information needed, just let me know.

I would really appreciate your help, and hoping on resolving my concern in a timely manner.

I'm really confused about how profiles and sync work together for what I assume is a pretty common use case, especially now will all the WFH. I have two devices:

1. Personal laptop 2. Work laptop

I'd like to keep my bookmarks, history, addons etc separate, but be able to access my work environment when working from home on my personal laptop. I've read a lot about profiles and sync and multi-account container but I'm still confused as to how I achieve what I'm trying to do.

Having multiple profiles on one device is straightforward. But AFAIK if I attach two profiles to the same sync account, and try to sync both between two devices, it will only sync one of the profiles (and then merge everything if I try to sync the other). And if I have two separate sync accounts (work and personal), each with a single profile, I can't switch between them without also merging everything. How does one achieve this then?
