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!

15/12/2025 I need to sync my firefox data from my old windows 10 laptop to my new windows 11 laptop. Do I have to download the firefox app on to my new laptop before I can sync it, and will I need a new password if I have to download the app. Im using my old password on my old laptop to write this. On the new laptop, I tried to sign into firefox on the internet but, it said my password is wrong. I'm an oldie and have no idear what to do. Iwill be very grateful for any help. Many Thanks,

                                                                                           Janet.

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

Dear All, I recently reinstalled Windows and updated to the latest Firefox. When I tried to sign in to sync/restore my bookmarks, Firefox could not recognize my password. I reset it and used the new password, but the bookmarks that appeared were outdated, and not all information synced to my current account.Could you please advise on the steps (or a quick solution) to fix this?Many thanks for your support in advance.Kind regards, Tareq Zeyad

I have Firefox reinstalled, it is not syncing bookmarks, history. I tried to import booksmarks from edge but it could not find the file or said it does not have any bookmakrs on it which was not true.

I cannot log into my account and synchronize my data, logins and passwords. I downloaded the latest version of the browser on the official website. Below I will send screenshots proving that there are no buttons or anything that would indicate at least the slightest login to your account. BUT YOU'RE SHOVING YOUR ****** AI BOT EVERYWHERE.

You need to enable me to sync the desktop to my mobile phone. I've had mozilla firefox on my Mac and android phone for years but now I am expected to work out how to create a back up and then delete all of my data and trust it will upload to the new browser on my desktop -- which before the update held the same data. Really unimpressed. Get it sorted.

I have 2 PCs and one has all my current settings and the other does not. I recently had to re-install Windows 10 and when I installed Firefox again the settings won't sync. Bookmarks, toolbars, etc.
