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.

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 recently upgraded from Windows 10 to Windows 11. I was under the impression that my bookmarks would be saved to my Mozilla account and I could then log in on the new computer and the bookmarks would come over also. Is this accurate or will I have to go about recovering my bookmarks a different way?

As of now when I log into Mozilla I get a message at the top saying "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. I clicked Learn more and tried the troubleshooting options, but no luck in fixing the message or issue. Thanks for your help.

The subject says it all. The "tabs from other devices" are a) Shown as a long flat list of links, not in their individual tabs, which is disappointing b) right click does nothing - doesn't open them as advertised

I have 3 devices connected to Mozilla account, 2 smartphones and 1 PC and NONE of them are syncing properly, bookmarks sync perfectly and everything else fails miserably. Some part of history does sync but nowhere near the full history. Syncing of open tabs is *completely* broken.

After Installing new system on my laptop and singing in to my Mozilla account nothing was restored from it. Everything is empty as it is completely new account but I created this one few years back and never had a problem with a sync. Hopefully it will be restored since I had large amount of important bookmarks. If you can check and resolve it please. Thank you.

захожу в свой ак, но ни закладок ни паролей нет, год назад синк работал, все перенеслось, даже если и отключил синк, то должно же хотя бы годичной давности все перенестить

Witam , Zakupiłem nowy komputer , zalogowałem się na swoje konto Firefox . Zrobiłem synchronizację , ale żadne dane się nie pobierają , ani zachowane zakładki oraz zapisane hasła. Chciałbym odzyskać te dane. Chodzi mi o dane z 14.11.2025 Dziękuje i pozdrawiam

after a fresh reload of windows was performed on my machine, I signed into my Mozilla account but none of my bookmarks were appearing after the successful sign in. When I tried syncing it still did not appear. There are bookmarks that I had saved on firefox that are essential.

Hello.

I have made a fresh install of Windows 11 from Windows 10, and after logging into my account everything syncs, apart from my bookmarks. As i have made a fresh install, i deleted all of my old files on the computer. Is there any way to get my bookmarks back?

Hi there,

I've recently made the move to Windows 11, and since then I've been having loads of issues with firefox hanging and crashing. I've been able to correct the issue for about a week at a time by clearing my startup cache, but I did so incorrectly recently and it corrupted my profile, resulting in the need to create a new default one.

I'm able to launch firefox okay now, but when I try to sync my bookmarks and settings, firefox freezes every time immediately upon login. Is there a way I can sync my settings without using the firefox UI in order to circumvent the crashing issues present in the UI?

I wish to switch to a new primary laptop. I normally use multiple machines in the course of a day. I have probably hundreds of open tabs on my main computer and even though I checked "Open Tabs" for sync, they never show on my other devices.

Following previous help recommendations I searched for the json sessions file...it doesn't exist anywhere on my system. The only other "help" was to "tap" tabs in the lower right corner. There is nothing in the lower right corner unless, perhaps on a phone, which isn't the device in question.

Please help

Firefox was somehow reset after windows update restart. I was trying to sign in to sync, but sign in button gets blurred/disabled, and nothing happens then. I am afraid that I lost my previous session also.

I was trying troubleshooting mode too, but behavior is the same.

Otherwise I can login to my Firefox account web, and I am logged in on my smart phone still.

I have a profil i didn't use since 22 days because computer issues

I need to retrieve ALL my tabs from this device For some issues i could'nt to it all before.

Now, i can see in my firefox profil pge, the profil exist. But if i go to my firefox installed in my new computer, i don't see THIS firefox device with ALL my VERY IMPORTANT tabs.

Is there any way to retrieve them ?
