Hello I just formated my laptop.I installed mozilla and logged into my account to sync everything.I was waiting half an hour just to realize at the end that nothing was synced and nothing can't be synced anymore,like i lost everything passwords bookmarks etc. I'm pretty sure that was my account on mozilla and i activated sync before i format.. what can be done?

yours sincerely

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.

Take a look at the screenshots. The second device is called "Firefox on HUAWEI LIO-L29", but I renamed it to "Mate 30 Pro" (screenshot 2).

Why is the device name displayed not "Mate 30 Pro", as in the case of "Macbook D14"? I renamed the device in Firefox settings a few days ago.

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

I am trying to add a secondary email address to my firefox/sync account but there is not button to add a new address. Help articles state that there IS a button, but I don't have one. Thanks.

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 know there's [[an article|https://support.mozilla.org/en-US/kb/sync-custom-preferences#w_sync-custom-preferences]] on how to sync custom preferences. I wanted to sync my toolbar customizations and some other preferences like disabling disk caching. And I don't even have other firefox instances, instead I just want to sync only on one device, so that I can continue the same setup when I signin later on the same device.

I've tried to add services.sync.prefs.sync.browser.uiCustomization.state, "services.sync.prefs.sync.browser.cache.disk.enable" and set it to true. But it doesn't work. What am I missing? No one seems to address this. May I am missing something.

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

I initially just wanted to get some ad-blocking program to keep down the volume of all the flashing ads showing up on webpages. I'm working with a new laptop computer, and my old laptop had been "tweaked" with some Mozilla extensions (?) to address this, and I wanted to get the same on my new laptop. So I opened the application menu - the 3 horizontal bar icon, top right. First thing at the top, it asks me to sign in. Honestly, I don't think I ever did this. So I used one of the many secondary email addresses I use for this type of thing, put in a password, and created an account. Up popped a screen saying, "This Firefox is connected". Then down below, it said, "Sign in to Firefox on another device to complete set-up". Ugh, really? Ok, fire up the old laptop and open up Firefox and sign in using the same email and password. Here's where I get lost - up pops a screen that says, "Connect another device". Then down below it says, "Open the code scanner on your Firefox app and show code when ready." And there's a "Show Code" button down below this. But I'm hesitant to press it, because I don't know what my code scanner is, I don't have a flatbed scanner (if that's what they're talking about), my phone is broken (part of the reason I have a new laptop today), and I don't see any Firefox apps called "code scanner", and nothing in the help community that I can find about code scanning. So what the hell? I can't be the only person who's gone down this rabbit hole...

Just noticed today that Firefox on my work computer (Mac) is adding an icon to the MacOS Dock that opens the URL of the currently active tab from Firefox on my personal computer (also a Mac). Firefox on my work computer is signed into Sync w/ my work Firefox account and Firefox on my personal computer is signed into sync w/ my personal Firefox account. This is crazy and unacceptable.

I have not previously signed into my personal Firefox account on my work computer, the Connected Services section of the Firefox Account Settings for my personal account does not show my work computer and the Connected Services for my work account does not show my personal computer.

Both computers are on the same physical network, but do not otherwise interact.

Following direction on Help Page - Trying to sync tabs, bookmarks etc from one laptop to another. In settings, devices are said to be logged in and sync set to sync pretty much everything. Clicking the menu top right - only shows my email @ the top, then New Tab etc - but nothing about "Sync Now" or "Sign In" What am I missing? TIA, Jean

I've just set up Firefox Sync, but it is only working one way. I can see my computer's tabs from my phone but I cannot see my phone's tabs from the computer - if I use the quick access "Show tabs from other devices" it just spins a loading wheel with "Syncing".

Also, the "Send Tab" option when you right click a tab does not appear at all. Sending a tab from the phone to computer does not result in anything appearing on my computer.

Everything is set to sync on both devices, and I have tried to sync it manually. Both versions are up to date.

I will sign into my firefox account when on a new computer to access my bookmarks/passwords etc. When I sign out, after I am done using the shared computer, my bookmarks and passwords remain.

I even uninstalled firefox, but when I reinstalled it the next time I used the computer, all of my bookmarks and passwords were again available without signing in.

How do I remove these from the shared computer without deleting my firefox account?

I am running Linux version of Firefox. It has just upgraded itself - without any warning that logins and passwords would no longer be accessible The upgrade cannot read previous version of my profile, so I cannot access login and password from my old profile I have used Profile Manager, but it refuses to open my previous profile with the updated Firefox. How can I access my passwords from before this update?

I've reinstalled my PC. First thing first I downloaded FF and installed it. Login to Firefox Sync. And it's empty. No history, no tabs, no passwords, everything is gone. I've check that I logged into correct account. And yes I can track many previous emails from this account. Why did Sync lost all data? Is there a history that I can use to restore my lost data? Thanks!

Firefox can't keep login even other sites like :Youtube Facebook... Every time I exit Firefox for a while and re-login, the logins to websites log out and have to log back in again and again (I've tried uninstalling Firefox and reinstalling it, and the problem persists). ( I think due to the settings for Firefox )
