Recently I am facing this weird issue where every time I open FireFox, all my previous tabs are gone and it starts with a fresh window.

This happens even after the Account Syncing is turned ON under "Accounts And Sync" and "Open previous windows and tabs" is checked under the "Home and Startup" settings.

Hope someone can help me out as it is very frustrating to open the same tabs again and again!

i have 4 computers and 1 Apple phone that all have Firefox installed. I used to be able to sync all of them with no problem but now it seems it has become extremely difficult and I can't seem to be able to do it as easy any more. My main computer gives me a QR code to scan on my mobile phone but the directions are not clear as to whether I should use my QR reader app or my mobile phone camera. i have not been able to sync my devices because I am having issues signing into my Firefox app on my mobile device. i am just about ready to scrap Firefox on all my devices and start using another browser as it's gotten more difficult to use Firefox. And I would like my old layout for my Windows 11 computer. i do not like the new layout.

When I scan the QR code to connect the phone to the computer to sync the bookmarks etc, the next screen asks for an authenticator code- I don't know which authenticator app I need to use for this step in the process

I have firefox on my home computer, and I finally got the school to allow me to use firefox on the school computer, but when I signed in with the same account, and turned on sync, nothing has changed. All the bookmarks and extensions and stuff is all still the same thing. I even pressed the sync now button, and still nothing happens. Am I doing this wrong? Does anyone know things I should check?

I added Firefox to my new laptop and needed to reset my password to login. I recognize a few of my old bookmarks at the top but all of my passwords and login information is gone and none of my old devices are showing up. I have never encountered this issue before, please help.

My firefox app has recently stopped showing any synced tabs from my desktop at all after i open one of them. It will sync once briefly and I can open a single tab, but if I am trying to get multiple the sync page of the app is blank the second time I try.

I have had this issue happen before but usually it's just for a little while and fixes itself. It can be fixed by manually syncing both mobile and desktop simultaneously, but that requires me to be in front of both my phone and my home computer, defeating the point of being able to continue browsing at any time.

I have not been able to access my desktop tabs via my phone for almost a week now and it's getting extremely frustrating. I want to be able to leave my house and pull up what I was looking at on my computer without having to struggle for 10 minutes before leaving with ensuring the sync goes through.

When I manually sync on the mobile app, the sync button keeps spinning forever, I have let it run for about 25 minutes straight with no results. I have force closed the app to no luck. I have also tried closing and leaving it alone for hours and trying again with no results. This was not happening to me a week ago and I have not changed any settings on either device since the change started.

I'm not given the choice to STAY LOGGED IN and every time the system logs me out, I'm going through the motions of restoring my bookmarks. Isn't there a way Mozilla could fix this by allowing the bookmarks to be restored to the last login or give the user the choice to stay logged in? Better yet, DO BOTH. You know your the ONLY web browser that I've ever used that fails to do this. I'm sure their are dozens of programmers that could spend 30 minutes coding this into program. A few lines of code or a HOOK to fix this.

I stopped using Firefox on my desktop and began using Edge until it was necessary to have a Microsoft account for it to fully function. Then and only then I returned to Firefox.

Help us out here people. This is a real "rock in the shoe" issue.

Download FF install sign-in > said success then show warning

``` Are you sure you want to sign in to sync?

A different user was previously signed in to sync on this computer. Signing in will merge this browser’s bookmarks, passwords and other settings with xxxx@gmail.com ````

Press continue, the pop-up still appear and the sign-in was false positive.

Hello,

I have been facing an issue that I want to completely delete all of the bookmarks associated with Mozilla Firefox. Manually deleting them works temporarily, however, they return to the bookmarks bar upon reinstalling Firefox and logging on to my account

I have already tried deleting my Mozilla account completely and used RevoUninstaller to delete all and any Firefox files from my system (done this to one of my computers). Still, the bookmarks return when I reinstall Firefox and log in to my account. I have also tried not syncing with other browsers, and the bookmarks still return when I log in to the Firefox account.

This persistence is annoying, because I really would like my bookmarks data from Firefox to be completely wiped out, but it seems that they are returning even upon account deletion (I created a new account using the same old e-mail).

Could someone please help me with this issue?

Today, 17Sept2026 I want to synchronize my bookmarks, extension and profile data to a new Laptop. From Profiles I see more than one default backup. Says Sync not working for my version of Firefox for one help page, but Syc is ON from Account and Syc. Everything went automatically on old Laptop. Give procedure or page to do this on new machine. From this PC I see multiple "Default" profiles. Which to use? Or does this happen automatically if both machines are on? The latest is Today, updating every few seconds

Hello,

I discovered that my android application was no more synced. I follow the procedure until Firefox must normally send me a code to my email address. The address indicated is correct but i never get this code. I try this 2 or 3 times before contacting you. Could you help me and verify if this process is well working ?

Regards
