Firefox Support Forum

Some years ago I had to replace my PC and thought - Wonderful - just use sync to bring back all my tabs etc into the new PC...

The long and the short of it (in the past), was that Firefox decided that the new PC was the one to be synchronising source, and promptly removed all the apps/tabs etc. so sync was in line with the new PC - erasing all the app data. I understand there is no 'Master' sync account.

The question is, how can I stop Firefox initially migrating the Firefox app data in the wrong direction? I know that the app/tab data is currently still correct as my laptop still has all my apps etc. Is there some way to stop Firefox thinking the latest clean browser on the new PC has the correct (None) apps etc? Has the laptop to be logged-in and currently on-line before starting the new PC with Firefox? Is there a process to follow with a new 'un-synced' PC?

Sorry if I'm making things sound difficult, but don't want to loose everything which is currently correct and still these within sync data. It's maybe something that can't happen in these later versions of Firefox, but I want to be sure before logging in my new 'Blank' PC.

Why you create Mozilla account with sync, if I can't use profile which I saved on my old PC. I change my PC and now I can't use my open tabs as needed, I need to open each tab one by one. Why ??? Why I can't use saved profile on my new PC ??????

I have completely separate bookmarks and bookmark toolbars on my work PC and home PC. I do log in on my home PC as to not lose my personal bookmarks and passwords. I accidentally logged into Firefox at work and it merged my bookmarks from my home PC. I logged out of Firefox on the work PC and removed the bookmarks that were imported from my home PC profile. I then tried to make a new account with my work email and login to sync on my work PC but it always says primary email needed and I'm stuck. I did go to about:profiles and add a work profile but that doesn't help me. I need to make a Firefox profile on my work PC with my work email address but the primary email thing gets me. Is there a way to do this with my current work PC bookmarks not lost? Thanks

Hi, Could you recover for me last session, which I was used on my account? I accidentally logged off, before I opened last session on the new computer... please advice. Best regards, Krzysztof

I use Firefox as my default browser. I have sync turned on. Im signed in thru my google account. Firefox does NOT sync to my Chrome browser and Google account. Whats the fix?

Fix it so the FireFox browser Version 88.0 for Ubuntu (Linux) works AGAIN at saving website Login data using a Primary password via your 'FireFox Sync' advertisement (documentation).

Hello, I just bought a new laptop, and am trying to sync my firefox account.

The new laptop wouldn't accept my password. So I changed it to a new one.

It doesn't accept the new password either. And now it seems like firefox isn't allowing me to logout of my account either. What is going on with the passwords? I can't afford to reset everything and lose all of my data and log ins. They have been generated by firefox and are all randomly alfanumeric.

What am I to do?

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. :)

Hey, I just reset my computer, reinstall firefox and it sync correcty. But I had to delete the windows session to create another one to be in my domain. Now when I try to resync it just load and then stop over and over again. I didnt do anything to delete the sync option on firefox.

I have 2 Firefox accounts and I want to import or copy my passwords for the account that still has them to the one that has lost them. I synced one account in Firefox BETA that has my passwords. My other account I used to sign in on Firefox and all logins and passwords are gone. How can I do this and not loose my passwords I have in the BETA version?

All my available devices do not display on screen when I am in tab share mode. I receive Tab Sent notice when sending, but new tab doesn't show up on other device. When I sync my device it says sync complete, however nothing seems to syncs ever, tabs on browser don't sync with anything, but nothing different on other devices. Open tabs on one device do not migrate to other devices when Firefox browser is opened. New desktop pc does not show up as available device to sync with or send tabs to. All devices are signed in and synced yet nothing really syncs

i have re-install new windows and download fresh firefox and sign-in when i sync my account i didn't find any data (passwords , bookmarks , history , etc ... ) i found my firefox account as new

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
