I’ve not had much success with my online searches to learn the details about what takes place when Firefox syncs browser information across devices. To keep things simple, assume I interested only in syncing bookmarks and staying within the Firefox environment, i.e., no syncing to another browser. Please note that I am NOT asking for help in setting up Sync on different devices or in how to turn Sync on and off. Rather I am seeking help to understand what “sync” means, that is, the details of the sort of information transfers that take place between individual devices and the Firefox Sync server.

Here’s what I currently understand. After signing in to my Firefox account on Device 1, setting up syncing on that device, specifying that I want only bookmarks to be synced, and turning syncing on, the set of bookmarks on Device 1 is sent to be stored on a Firefox server. After that, whenever one is signed in to the Firefox account on Device 1 and syncing is turned on, any changes to the bookmarks on Device 1 will "automatically" (but I don't know how quickly) end up being reflected in the set of bookmarks stored on the server. Fine so far.

In addition to Device 1 I have another device, Device 2 which has not been set up for Firefox Sync. It has its own set of bookmarks. Some of them are also on Device 1, some are not. I sign into my Firefox account on Device 2 and set up syncing on it. I follow the steps for doing this in https://support.mozilla.org/en-US/kb/how-do-i-set-sync-my-computer, “Connect additional devices to Sync.” I then click Sync Now. OK, now what happens?

1A. Do the bookmarks in Device 2 get added to the bookmarks stored in the Firefox Sync server? 1B. Do the bookmarks NOT in Device 2 get deleted from the bookmarks stored in the Firefox Sync server?

OR

2A. Do the bookmarks stored in the Firefox Sync server get added to the bookmarks in Device 2? 2B. Do the bookmarks NOT stored in the Firefox Sync server get deleted from the bookmarks in Device 2?

After whatever transfers of bookmark between Device 2 and the Firefox Sync server take place, and assuming that I’m still signed in to my Firefox account on Device 1 and that syncing on that device is still turned on, what sort of transfers of bookmarks takes place between the new set of bookmarks stored in the Firefox Sync server and the set of bookmarks already on Device 1?

3A. Do the bookmarks then present in the Firefox Sync server get added to the bookmarks in Device 1? 3B. Do the bookmarks no longer in the Firefox Sync server get deleted from the bookmarks in Device 1?

Finally, what happens to the set of bookmarks in Device 1 and Device 2 if I’m simultaneously signed in to my Firefox account, syncing is turned on in both Devices 1 and 2, and a bookmark is a) added to either device OR b) deleted from either device?

I’m sorry this message is so long, but I’ve wanted to be clear about the things I don’t understand in regard to Firefox Sync. I’d really appreciate what anyone can say to help me clarify these points. Thanks so much.

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?

Hello Please explain to me how to transfer tabs from desktop to Android phone because there is no option on my desktop browser settings and no matter how much I sync, the desktop tabs will not be transferred to the phone again. please guide me

My old PC still shows up on sync. I can't remove it because I took it apart when I built my current PC to reuse some parts. Is there a way to remove it from sync or am I stuck with it showing up?

Hello,

I have 3 different profiles and I'd like to have a visual indication of the currently active profile. I've found that using themes is the best option (a red theme for production, green for test, grey for default) but I can't prevent Firefox Sync to sync the active theme between my profiles.

I have set both services.sync.prefs.sync.extensions.activeThemeID and services.sync.prefs.sync.lightweightThemes to false and restarted all my Firefox profiles.

After a while, all windows/profiles are synced to the same theme.

Are those settings really read by Firefox Sync ? I'm on Windows 10, Firefox 91.10.0esr (32-bit)

Thanks in advance for your help !

Hi guys.

I'm wondering if it's possible to send tab from macOS Firefox to another device... I couldn't find any clue to achieve that, since that right click doesn't have the option to send tab throughout the devices like on windows.

Tks.

Hello . I hope you be fine. After reinstalling Windows, I installed Firefox and enabled Sync. My addons synced on firefox but my bookmarks didn't. I had very important bookmarks. I tried everything but my bookmarks didn't come back. Please help me to fix this big problem.

Hi there! I have a new S22+, all systems up to date. I'm logged into Firefox on both the Android and on my Mac Air.

Last time I migrated to a new phone, Sync filled in all my passwords on the phone. This time I'm having to copy and paste all the passwords; Samsung autopass (or whatever it's called) offers to fill them in, but of course doesn't have those passwords anyway.

What do I need to tweak or do differently to get the passwords to fill in?

I was trying to use the sync function on my MacBook Pro. However, the browser does not seem to log in at all. In the top right menu, it still shows the "sign in" button, instead of my email address. (see the attached pictures which I captured from my mac and a virtual machine running Firefox ESR on Debian. Another test on the flatpak version on the vertural machine apears to be normal.

Checks on account activities indicates the login histroy exsits, yet the syncing function remains unavailable.

the browser on the Mac is Version 102.0.1 (64-bit) which apears to be up to date the browser on the virtual machine is Version 91.11.0esr (64-bit)

information for the systems and machines can be found in the pictures attached.

I have tried this several times over a few years, and have never got it to work I know it must be something I am doing wrong because if it was a glitch or bug, it would have been fixed by now. Usually I need to do this if I need to reinstall the OS, (Windows and Linux), or a new pc, the usual, but this time I had a major crash, so I'm starting over.

Anyway I have signed in on my pc to my FF account, and went through the menu to turn on sync, and I get to the page where is says, "when ready click next to display the QR code". I get my android out, open FF, sign in, click the "Scan" button, the FF scanner opens,, I open the QR code on the pc, (I have also went to the website to get a QR code). Then either way I scan the code, and get an errror msg "Must scan from inside FF". I am scanning from inside FF, with the FF QR scanner.

I don't uinderstand how of the 20 or more times I have tried to do this, I can't get it to work. I don't understand how I screw up every times, over a few years. But I also know as I said, if it was a bug MOzilla would have fixed it by now. Usually I give up on that and just log into both the pc and the phone, close both browsers and reopen them and it will go ahead and sync.

But not this time, I am unable to get it to sync for anything. I've been working on this for 3 days now, and at this point I'm confused, I don't remember what I have and have not done. Let me add, and I don't know if this will make a difference, I don't think so, but what do I know? Originally this all started, when I had to reset my password. I tried for 4 days there to get a recovery code to work. (The following is just to describe what I've done, and is not a second question) I had one downloaded, and saved on my pc. But no matter what route I took to go through the reset process, exactly as described in the help file, I never could get a place to enter the code. I read every article I could about it, and finally it seemed easier to just reset the password and resync than try to get the code to work.

Which is why I am sitting here, desperatly needing to sync my data, but unable to. If anyone can tell me what I need to do I will appreciate it. If you need any more information, just let me know.

Hi,

first of all thank you all in the community for your amazing work on Firefox!

I have cloned my $HOME (including ./.mozilla/firefox/) to another Linux device.

Now I realize that changing the Firefox Sync device name on the new device would also change it for the other device when checking "Connected Services" https://accounts.firefox.com/settings. I also can only see the new device name when using "Send to device" from any device.

I guess I have to unlink my new device and somehow assign it a new device ID for Firefox Sync to recognize the new device. How can I do that?

I am not a geek and I follow all the details of 'how to etc etc' but nothing works and the phone goes into random loops and keeps telling my I cannot sync (I KNOW that). Firefox has no phone number or email system for technical support (or any type of support) just this hit and miss system of 'forums' (or is that fora). I tried to send a bug report but I am NOT signing up for another (geek speak) account just to send you the problem. Please fix this issue - it never used to happen on older versions - how can I roll back my firefox to something that works properly?? Here is the error report, enjoy, to me it is written in ancient g(r)eek!

I reset my PC and reinstalled Firefox last month, but my bookmarks were never recovered after I logged in my Firefox account. A couple of months ago I installed Firefox on another PC (to which I no longer have access) and it showed all the synced bookmarks, but this time it doesn't. What should I do? Thank you

I set up sync before reinstalling Windows 10 on my PC, currently everything is still intact on my iPhone, but gone on the PC, because I reset my password?

How can I get everything back in Firefox on my PC?

Excuse me, I realize there must have been many similar posts.

Hi,

I use firefox on both a work and home computer, as well as my phone (iOS). I have sync active on all three devices, yet the synced tabs only ever shows one device's tabs. On both computers, the iOS tabs are all that displays in synced tabs, and on iOS, only one of the two computer's tabs are shown, and often with the wrong name - I haven't found out what determines which computer's tabs shows in the synced tabs menu or which name is used, but it definitely isn't which computer was used more recently, for either requirement.

I have recently updated my OS (Android) and reinstalled Firefox. I am now unable to sign in (only on THIS PARTICULAR smartphone). After entering my email and password Firefox redirects me to the accounts settings page and everything seems fine. However when I tap on menu button I still get the "Sign in to synchronise" prompt. Any help would be greatly appreciated.

This morning I had trouble updating my Firefox after the new update. Went to our IT people, who uninstalled Firefox, and installed a new one. The new one updated fine. However, I had forgotten my password, and had to reset it when logging in into the newly installed Firefox. Now I am logged in, but cannot see any of my bookmarks, etc. Essentially Firefox is treating my account as a new one and does not remember any of my settings. Is there anything I can do to recover my settings and bookmarks?

Thanks, Yuri
