I have seen multiple copies of this question, some unanswered, some with the same "answer". All the questions are closed so I cannot reply to them. The "answer" does not work.

I have the "Show tabs from other devices" sidebar. I also can access from "Open application menu" > email address > list of synced tabs. Both methods show me the device name and all of my synced tabs. Neither method has an "open all tabs" option. If I right click my device name nothing happens. If I right click a tab, it opens that one tab. I don't know how many tabs I have on my Android. I have enough tabs that it only shows the infinity symbol instead of the number. It has shown the infinity symbol for a long time and I've opened many more tabs since. It could be hundreds or even thousands of tabs. I have 224 tabs on my laptop. I want to open all 224 laptop tabs plus all however many Android tabs on my laptop at the same time. I'm aware this will cause significant lag on my laptop. I'm not looking for a solution for that or people telling me not to do that. I want to know how to open all of my synced tabs at once on my laptop, without having to click through one by one.

Firefox 113.0.1 (64-bit) "Firefox is up to date"

I've just had to completely reinstall windows without being able to backup my files (I couldn't launch my computer in order to actually back them up) meaning I've lost my recovery codes. I thought this would be fine as I could just sign back into firefox on this new install of Windows but as it turns out I must've forgotten to put my sign in information into my password manager. Again, I thought this would be okay as I still have access to the email I used to sign up to my firefox sync but I got the message saying I'd lose my data which isn't fine and now I'm at a bit of a loss. I've had to use a spare email to make an account and ask here but I'd really love my old account back. Is there any way at all I can get back into my account without losing my bookmarks and passwords? If not, how much information would I end up actually losing? I'm slightly unclear on that part. Do I lose absolutely everything? I'm a bit stressed about all of this ontop of losing all of my old computer files so I'm sorry if this is a commonly asked question but I was struggling to find anything that helped me D:

Any advice at all would be really appreciated thank you so much!!

Hey all,

after 3 years I finally did a complete reset (all folders were kept, only full software reset) of my system hoping that Firefox Sync would after I reinstall Firefox and put in my registration data remember all my bookmarks / logins. However, after my login there is nothing there. I have the suspicion that Firefox thinks I just deleted all my bookmarks and it updated to Firefox Sync accordingly not with an empty space. I still have the data on my android phone which hasnt done a synchronization yet. Any help you guys can give me? Took quite some time to get all my setup arranged.

Thanks in advance!

Best, Seb

my older asus laptop had a critical failure and I needed to get a new computer and to my understanding when you have had a Firefox account for as long as I have you should be able to sync your whole account to a new device to my dismay that is not the case and I have years of bookmarks and history on my account urgent fix would be appreciated.

I am using Firefox Developer Edition in a work environment that only saves directories between weekly restarts by explicitly managed rules. As a result of some missing folders from my weekly restarts, I need to sign in to my Firefox account and enable sync each week. Currently my machine retains the %APPDATA%/Mozilla and %LOCALAPPDATA%/Mozilla directories + children.

What other directories are needed by Firefox Developer Edition in Windows to retain the user profile/syncing, et. al.?

Thank you for your time!

Hello:

I have 2 profiles in use. 1 for personal use with their respective bookmarks, passwords, and extensions, and I have no trouble syncing with this one. However; profile 2 that is for work use that has its respective bookmarks, passwords and extensions, has become a nightmare.

It happens that I have both profiles on the same computer and when trying to create an account in Firefox, the system asks me to enter the email registered in profile 1, with the warning that bookmarks, passwords and extensions will be mixed.

I mention that I have migrated from Google Chorme to Firefox for speed reasons and because I use windows 7 (I don't like later versions) Now well; in Google Chrome you could create as many sessions as were registered but in Firefox you can't.

Oh! I have been working fine with Firefox but suddenly an error occurs (it has happened to me 2 times in the last 2 months) in which the program closes and all the data of my profiles stored on the pc DISAPPEARS or is deleted (including cache), when I want to open them again:

firefox.exe -P

Then I have to give myself the task of synchronizing profile 1, but profile 2 I have to be importing from my previous Google account or importing a backup Bookmark.

The option to copy and paste the data from Firefox to replace it in the path (supposedly brings with it the data of everything):

C:\ProgramData\Mozilla-1de4eec8-1241-4177-a864-e594e8d1fb38\updates\308046B0AF4A39CB

with Firefox turned off it has not worked for me. Since when opening I see 2 profiles called Default "X" and Default "Z" without data.

This is a headache that if it happens to me, it happens to millions who have 2 or more profiles.

Why can't I sync a second profile? Why do you insist that there can only be one sync per device? Is there a solution for this?

Note: I have read all the tutorials out there and the situation remains the same. Synchronization with 2 or more profiles is never described.

Thank you very much to whoever asked this question!

I was signed in with FF and synced all data. I needed to re-install Windows, after installing FF on fresh windows and logging into FF account - nothing is synced. What have i've done wrongly?

Hi, not sure what I'm doing wrong, but my logins and passwords simply will not synch between devices. I principally use a desktop Win10 machine, and an iOS version of Firefox. Have double-checked settings on both devices, tried forcing a manual sync from each to the other, all to no avail. Any ideas on what I need to do differently? TIA.

I have two profiles on one computer and I want to use these profiles in different languages for web pages (one in English and one in my native language). If I sign-in the two profiles using one common Firefox account, this seems to be impossible: a change of the language setting in one profile immediately reflects into the other profile. Is there a way to disable the sync of language? I want histories and bookmarks to be synced across the profiles and thus I want to use the same account. Thank you.

So I'm using firefox on my old PC and want to export the login data to my new PC. Firefox has export passwords to CSV but there is no import CSV in firefox on the new PC. There's import HTML but... firefox exported to CSV not HTML so I'm really confused, why would it export to a format that cannot be import?

Well done Firefox team.

I got a notification this morning telling me I could update Firefox to the latest version and I had nothing urgent so I did.

Imagine my suprise when all my bookmarks, my passwords and logins appeared to have disappeared. Well, not just "appeared", since I can't find them anywhere on my machine right now.

I've been using Sync for years and when I finally managed to connect (because apparently the password I had been using was wrong ? But did FF tell me ? No ...), I discovered nothing had been saved. Ever.

A really nice morning.

I try to set up Firefox Sync on Firefox on a VM on Fedora. I enter my e-mail and password. Then I get the message (after retrying): "Email resent. Add accounts@firefox.com to your contacts to ensure a smooth delivery." However, I do not get the email with the confirmation code.

My email address has this format j@xxxxx.org

I have a disability and totally forgot about this question BUT it is still an issue I would like to find a resolution too, so I am going to try to restate it -- but know I stopped working 2 years ago ... so maybe a resolution isnt horribly required :P

My old question: (This is an issue regardless of platform - MacOS, Linux, or Windows...)

I do a lot of OS switching - I test various Linux distros on my (was 5) but now 3 laptops and one really old 32 bit system for my mother-in-law and I am wondering if I can use FireFox Accounts over and over without making a new service device every time I need something from FF Accts :P (I actually stopped using Sync mainly because of this 'Sync' issue -- how do I know what I have is actually being sync'ed?) I have learned to live with uncertainty not because Firefox is bad or anything but because "I want to be in control of my Data, not someone else...I had thought FF Sync would help me do that but I fear it hasnt and maybe because of my disability it has just gotten worse ..." ... not to even mention FF dropped FF Lockwise - which I loved!  :P

Anyways, this has bugged my off and on for a long time but I have mostly ignored the issue ... until a couple of years ago I discovered I had like 20+ some odd devices on my account -- going back 3+ years or more. Now, I signed out of many of them and I am down to about 15 -- mostly because I am a little confused about how FF Accts determines what to sync and when I start Sync are all of them brought back? Even from 6+ months ago? The one's that were years old I signed out of and deleted but still ... and so, since I use FF for testing and I thought that there shouldn't be that much in each 'sync' test device ... it is sort of confusing...

So, is there a way to use FF Accts 'sync' to get my data to a new device without making a new 'synced' device?

Thx/Bill

PS - in the FF past releases I got what I wanted by just copying the .mozilla directory to the new system but that broke a few releases ago :P too bad stuff has to change :(

Also, please understand that I am on Android, iOS, MacOS, and Linux daily so trying to 'gather' what I am submitting this question on will not lend itself to trying to solve my insanity >< Sorry!

PPS - I have not tried the first solution offered in the old question yet... I am leaning toward giving up on Sync and just using HTML Bookmark files ... it is messier but I know it is my data - unchanged and unyielding :P Thanks  :)

Hello,

I'm having trouble importing data I had on my account into the browser I'm currently installing on a new HP laptop. I logged in, but I can't see any of the bookmarks. I tried reopening the browser, hitting the sync button, reinstalling... Sync was working perfectly fine before, it was also transferring my config and extensions, maybe it has something to do with HP, as it automatically installed HP Wolf Security Extension. Would there be a way to restore all the settings I had before, taking in consideration that I logged out from previous laptop and I don't have access to it anymore, thinking it was all synced on the cloud?

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?

Hello friends There is a serious problem syncing my Firefox data. After I uninstalled the old firefox and installed the new firefox on the new windows, I logged into my firefox account but none of my old data was transferred. Plugins, bookmarks, passwords, and other previous information usually need to be synced. Please help me to fix the problem and sync my account information in the new firefox.

Note: I have been using this account for several years.

This all started when i wanted to use a user.js file for firefox.

I followed a youtube video to create a new profile to use the user script but I wanted to change the directory so I deleted it, made it anew and somehow the default profile file that i used was gone (I realised this only later). I think I had somehow overwritten it, but its weird because in my trashbin i did not find anything.

When asking me to login to sync I gave my password but it said it was wrong i realised I was using a vpn so i turned it off and then it worked, however then it asked me for a confirmation code from my email wich I also gave but it still refused saying it was wrong, which it wasn't!

After that I gave up and made a backup of my profiles and resetted my password still thinking I had my old profile file. My logins were gone and copying and pasting the login.json with the key4.db files from other profiles didnt give them back.

Luckily am still logged into my mobile app where i have my logins but there is now a warning sign to reconnect to resume syncronizing and Im afraid if i reconnect its going to delete my saved logins on the app instead of using them.

What do i do now? Is there a way to export all my data from the mobile app? Do I need to copy my logins one for one? Or can everything be resolved by reconnecting?

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.
