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.

My bookmarks on my laptop has lost 90% of my bookmarks. I try to sync with my PC but nothing happens and the laptop remains the same. I've tried closing the browser and logout and login again but nothing changes. I've turn of the laptop and turning on still nothing. How can I be log in and see a different layout, it doesn't make any sense. The only thing I have change on this laptop is down loaded a new version of CClean. Which I have already done the day before on my PC. I've attached a copy of both screens 743 is from my PC and the other 534 is from my laptop.

Hi. I am trying to migrate Firefox from my wife's laptop to her new one, using sync. I've followed the instructions, set up sync on the old one, then set up sync on the new one with the same account. Nothing changes! Where am I going wrong? Or will I have to do a manual transfer instead?

Hi, I created mozilla account and turned on synchronization to save my passwords, history, etc. After I done it, I formatted my pc. Now I've just downloaded mozilla and log in to my account to see that NONE of my data were saved... How is it even possible? I turned synchronization on and then selected which data I want to save. Will you be able to help my with that?

Instead of syncing my current settings, sync just overwrote them with an old, outdated copy from another device, completely ruining my addons, bookmarks and various other settings. I managed to restore the bookmarks, but is there really no proper way to undo this or prevent such thing from happening in the first place? Is there no way to control if I want to sync my setting TO the server or FROM the server? How such a vital decision is even made then and why wouldn't there be a way for a user to control that? This is so disappointing :(

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.

I logged out of my Firefox account, then reformatted my PC.

After reinstalling Windows 11, I installed Firefox on the PC computer.

When I signed in to Firefox, I expected to see my saved tabs just like I had seen them before. There is no sign of any of my previous tabs.

All my previous Shortcuts and Bookmarks are all fine.

How do I restore the previous tabs?

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

As in subject ... None of my bookmarks (for instance) in my previous browser on an other computer will show up. I have tried to manually sync but nothing happens ...

Best, Johan

I moved to the Firefox flatpack after the Debian version couldn't display the code inspector/ web developer tools anymore (it was blank amid other likely javascript-based rendering errors). I only include this context in case some one else has the issue and searches for it.

I want to sync all my tabs from the Debian version to the flatpack version and similar to this solved issue I cannot access those tabs from the firefox view. However I am also unable to access these tabs from the sidebar. I am only able to access these tabs from the account menu but this would have me open each tab individually which is not feasible for me.

Is there a way to fix the "Check your internet connection If you’re using a firewall or proxy, check that Firefox has permission to access the web." error that comes up in both the Tabs from other devices sidebar and Firefox View menu?

after reinstalling the OS, Firefox stopped synchronizing most of the data. Bookmarks were not transferred, and passwords and extensions were transferred less than half

non my my bookmarks and passwords are on my firefox and i reformatted my pc, i have never had a issue like this ever, and yes im signed into the same email i have always used and didnt do anything different

I have multiple devices all using Firefox with the same account. On one of the devices I swapped the motherboard and since all payment methods in firefox disappeared. Syncing is active across all devices. On all other devices the payment methods are still available.

On the device with the new motherboard, I tried to disable payment methods sync and re-enable it but the payment methods list is still empty. How can I restore all the payment methods on this device? Why they are not syncing?

Thanks
