Hi there, I'm hoping someone can help with this. I recently signed into a shared computer with my personal Firefox account, and it automatically imported all my history, my browser extensions, and bookmarks, including personal/secure information that I wouldn't want on a shared computer. I tried signing out and deleting the sites and login information, even going so far as to completely delete all of my browsing history and cookies and signing in with another account, but all the supposedly deleted history and logins and extensions were then transferred to this second account. I have deleted all my data, even uninstalled and reinstalled Firefox, and all the data from my personal account keeps haunting me as suggestions when I type in the task bar or suggested usernames when I log in to websites. How can I actually delete this information so it's not on a shared computer? Thank you!

I cannot log into my Bank or puzzle> No internet? Trouble started with Firefox upgrade to must have Edge? Can you call me [removed phone# from public forum]. I am a senior and technically challenged and must make these corrections. Why did you upgrade and change everything?

Hi team, have reviewed few thread on Sync issue, but none was explicitly touching the issue I have. Running latest version on different PCs ( both Win10), using same account, I can't "send to" tabs among them. They are simply not in mutual device list. No problem to see mobile (Android here) devices in same account.

So, is this a recognized issue on PC with same account? I may just guest about HTTP "user-agent", same "display name" in Sync account and similar stuff in possible conflict, but better leave this on IT pros.

General issue is with speed of sync. If I open a tab, sync the device, then send to other device, sync that other too... and it's not instant there, even not after minutes. What could this be?

Though two questions, I thank for every reactions to them. BR Peter

The Send Tab/Link to Device feature only works in one direction, from iOS to MacOS. iOS to iOS never receives, although the popup says it sent. I'm using Firefox 98 on MacOS and iOS. I have a Windows 10 PC which can't receive or send tabs/links as well but I'll limit it to the Apple devices for the moment.

Sync and notifications are enabled on Laptop, iPhone, and iPad. I've de-synced and re-synced each device separately and together. I've attempted to send between each device separately and all together.

Neither iOS device can receive tabs/links from one another, nor send to each other. Laptop can receive tabs/links from both iPhone and iPad, but not send to either.

Each time I re-sync an iOS device I get a notification on the Laptop saying that "this computer is now connected with Firefox iOS". But still nothing works.

Hello Everyone,

I am not sure what has happened but I had tons of passwords saved in my Mozilla browser. I have been using this since 2019 or 2020 and saved all of my passwords there. What happened is I was using my laptop and wasn't aware that the charger is not plugged in. While working my device turned off because of no battery. I connected the charger and restarted my device like normal. After I opened my browser(Mozilla Firefox) and ctrl+shift+t to open all the recently closed tabs, I was amazed to see that it restored many old sites like 1.5 month old websites instead of the one's which I was using. However, the recently closed one's were showing in the history. I opened the tabs from history that I needed and started using it normal. I have using Mozilla Firefox for good 2 years I never felt the need to remember any of my passwords. Everytime I have to create an account on any of the sites I just create a password once, at the time of sign up only and then click on SAVE PASSWORD so I don't have to remember it. I am guessing this is the normal practice that everyone does or may be a cast majority. I was doing my routine work, I tried to login to my account using the same way like you put in your email in the email section and then click on password section and select the user/email you want to use a password for and sign in. BUT TODAY WHEN I FOLLOWED THE SAME PROCEDURE, IT DOESN'T SHOW ME ANY SAVED PASSWORD WHICH WAS QUITE SURPRISING TO ME. I OPENED THE PASSWORD MENU FROM THE TOP RIGHT AND I WAS SHOCKED TO SEE THAT THERE WE ZERO, LITERALLY ZERO SAVED PASSWORDS. I REALLY NEED HELP WITH THIS BECAUSE THOSE WERE SO MANY PASSWORDS LIKE SERIOUSLY SO MANY.

THANK YOU, AMIR

Is there a maximum number of tabs that can be synced? I have about 800 tabs on my old computer, but when I look at the synced tabs in the sidebar on the new computer, only about half of them are listed. The oldest 400 or so are missing.

And yes, I realize 800 tabs is insane. But that's another discussion. :)

I have a local Firefox profile that's contains all my saved passwords bookmarks and history. Therefore all my firefox data are saved on my local harddrive and they can't be sync across different devices unless I manually export/import them. If i create a new Firefox account, is it possible that I can import all my existing local passwords, bookmarks, history, etc onto my newly create Firefox account so they can be sync across different devices. If so, how?

Hi , My main machine is a personal windows laptop. Firefox sync works fine and syncs all things including "all" my installed extensions . recently company issues me a macbook and on it when i install firefox and login my account for sync it syncs other things like bookmarks but does not sync all my extensions only a few of them.

I already tried multiple things like sync delibrately from windows and then pressing sync on mac or reinstalling firefox on mac . but its the same issue.

few of the extensions that are missing :

1. Auto Tab Discard
2. Download Manager (S3)
3. DownthemAll
4. Stylus ( very important for me)
5. Tab Session Manager (THE most important for me)
6. TamperMonkey ( Important)
7. (Temporary Containers)
8. uBlock Origin
9. Xkit Rewritten
10. Zoom Image

I have reset my Windows 10 OS with the windows repair tool, I have since lost all the data linked to my account such as password, bookmark, profile settings, etc...

I tried to sync multiple time to no avail.

Firstly; I am 77 years and represent a non understanding in computing. I recently changed fierfox code to ensure contact between my mobilephone and a table computer. I dont remember the old firefox code. My bankid does not work after change. My question; do I need to give new codes to bouth devices shall i also change other codes making Sync. Thanks for help and sorry for my halting english. Yours kjell ryden

I have Firefox as my default browser in my Windows 10 Pro PC. I have a Firefox account and have saved bookmarks I want to be able to access from my Mac on Firefox, but I can't.

When I try to log in and sync I tried logging in on the Mac with my account credentials from the Windows PC (my username and password from there). I don't have 2 Factor Authorization turned on in the Windows Firefox installation. However, the login attempt on the Mac immediately asks me to enter a security code without telling me where in the world I would get that.

It does say to open my authentication app and enter the security code it provides. I had no such thing. After some searching, I figured I had to install an extension. I installed authenticator by Mymindstorm.

I tried following the instructions but there was no QR code to scan and I had no idea from where the code requested would come. It appeared I had to add a Certificate Authority Secret Key but again I couldn't figure out from where and all documentation and instructions were useless and uninformative to me.

I resolved to turn off 2FA if it somehow were automatically installed in the Mac instance of Firefox. I again couldn't figure out where you do that. I saw instructions but found nowhere in my Settings anything about that.

I'm baffled. Isn't there some easy way to do this? My Chrome settings and bookmarks are accessible no matter from where I install and use it. I have Chrome on my Windows PC and I can also access all my bookmarks from opening up Chrome on my Mac. Why is this so difficult? Can anyone give me the simple solution that actually works?

Even on my Windows PC where I am logged in to my Firefox account and I have my bookmarks that I want to access on my Mac Firefox, when I open the Authenticator extension it says no accounts to display. I follow the link to "add your first account." The instructions are mind-boggling. There is no QR code to scan. I go the to Mac and sync to log in. It asks for the code, but there is no code either to scan or to install manually. The instructions to add the code manually are even worse -- that CA creation thing referring to a Secret Key somewhere supposedly being provided to me. WTF?

I'd just shut it off completely if I could.

So I recently got a MacBook Pro and downloaded Firefox and signed in. For some reason, nothing is syncing. Bookmarks, history, passwords, everything is not syncing. I have signed into my account on 3 separate PCs and syncing works fine, just not on macOS.

Any thoughts?

Whenever Firefox tries to sync, which is naturally happening on startup, it crashes with no error messages. I ran Firefox in safe mode by entering the command firefox -safe-mode and the same thing as before happened, but before it crashed, Firefox wrote Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Segmentation fault in the console, and then exited to the command prompt. Help!?

Hello there, I somehow recently managed to delete my account by accident and I'm wondering whether it's possible to restore the sync data left behind, I have access to the recovery keys if required and can attempt to provide any information requested about the account. Not sure if it is even possible to restore the data using this method but it's worth a try at least. Appreciative of any assistance with this problem, thanks again :).

Hi. I was running into issues with my bookmarks menu bar not showing up. I tried hiding it and re-showing it. Didn't work. I restarted my computer. Still the same. So I uninstalled Firefox. After re-installing it, I tried to log in to my Firefox account to sync everything, but the sign in button just turns into a spinning wheel and above my profile picture and email address, it says "working...". It is just stuck like that. I've tried quitting out and doing it again. Still the same. I restarted my computer as well. Still the same. How can I fix this?

Hi! I have read that Firefox sync data are encrypted and safe. I would like to know if you ever had to give security authorities access to sync data, even though they are encrypted? Thanks.
