I've tryed all obvious instructions and my bookmarks toolbar will not sync

My account won't sync my old passwords and browser history. I recently reinstalled windows and when I tried to sign in to my mozilla account my data wasn't there.

The 2-year-old support page "View synced tabs from other devices" gives 2 methods for syncing all your tabs from one Windoze FF to another. Neither one does anything at all for me now. The "right-click on the device in the sidebar" sounded SO promising, but it does not cause anything at all to happen. And checking the "sync tabs" box does indeed make them all show up in the sidebar list, but does not open anything. So besides clicking on each of the hundreds of tabs listed, how can I do this, or is it just another FF functionality lost to time?

I have been trying to enable Firefox Sync on my Windows 11 PC (Firefox 145.02). I open the Firefox Sync window, I click on Log In, I enter my e-mail and click on "Sign up or Sign In" and then the view freezes and I never get any further. The attached screen capture never changes, no matter how long I wait.

Everything is gone, I have had to reinstall windows 4 times in the last week with a new PC and now all my sync data is gone...Chrome remembers everything fine and Mozilla did remember everything until this install and now its not syncing anything.

If this stuff is gone so am I.

Have tried logging in with my google account, tried logging in with Moz account, tried sync button over and over tried restarting, tried uninstalling and reinstalling and manually deleting all the folders STILL NO SYNC DATA AT ALL.......

Instructions everywhere say to open Firefox on mobile, select the options menu, and select "Sync and save your data." However, "Sync and save your data" does not exist. I cannot sync my passwords from mobile to my desktop.

I reinstalled Windows and downloaded the browser again. I logged into my account, turned on synchronization, but none of the data was synced. I am absolutely sure that synchronization was enabled on my old browser. I tried turning it off and on again, but nothing helps. Please help me get my data back!

Hi,

I use Firefox app in macos, android and ipados. The bookmarks across them are not synching automatically. I need to press sync manuelly to do. All apps are updated, all settings look fine. Please help me synch bookmarks across platforms. Thanks a lot.

Hello, when I first switched from google chrome to Firefox I could not figure out how to create one browser with two profiles like I had with chrome. So I went to about:profiles and created two separate browsers not realizing you all had an option to create two profiles under one browser. I finally figured out how to have to profiles under one browser by going here https://www.tech2geek.net/how-to-use-the-new-updated-profile-manager-in-firefox-2025/#google_vignette but I can not figure out how to sync the google chrome profile that I had previously to this new profile under the same browser. How do I sync this? I hit sync and nothing changed. I am signed in and I can not figure out how to get the browser profile to sync with this new profile under one browser. I really hate how Firefox named both of these Profiles because it is extremely hard to explain this situation.

Need to sync mobile and desktop with Firefox already installed using different email ID. Since new smartphone, thought it was safer. But unable to sync. Do I install new Firefox on mobile? Will I lose some saved sites on mobile?

I can't sync my new device without confirmation code! The email with it is not coming to this address: [email removed]@inbox.ru. I need this information from you: Full SMTP-log with ● Exact date and time of dispatch; ● Server response mxs.mail.ru; ● Correct sender and recipient addresses.

I had a previous account with firefox on a different computer and attempted to login on a new one, but once i logged in none of my passwords or data transferred even though it was the same account, just curious if there’s any way i can get my info onto my new computer besides using a sync key or manually importing it

Firefox won't sync anything since a while back, maybe since two months back, I am unable to force sync. Clearing cashe, uninstalling the app, relogging both phone and pc, neither of these syncs bookmarks across the devices. I am able to send tabs in-between the devices. Biggest issue is I can't save bookmarks on one device and expect them to be available on my other device Nokia 7.2
