The title pretty much sums it up. I even tried drastic measures such as logging out then completely uninstalling Firefox and removing any leftover data on both platforms. After reinstalling and connecting to the Firefox account they will sync with previous data but any new data I add on Windows won't show up on Android and vice versa. I also obviously tried forcing a sync manually... I really wish I didn't have to switch to another password manager any help would be greatly appreciated! :)

Running Win11 on desktop PC. Sync option offers QR code to scan but Firefox on android does not have sync scan option on settings. Despite instructions to contrary, that option is not listed on mobile. Yes I'm logged in and yes I have synced previous versions of firefox

Good morning. I recently changed smartphone, activating Firefox Sync between both devices, making sure that the old one didn't have the setting that makes open tabs inactive. Now after a week I don't see anymore synchronized tabs with the old smartphone. How can I solve it? Thanks, Phil.

Hello, everyone!

I'm encountering a perplexing problem with downloading .mobileconfig WiFi profile files through a direct link in my ReactJS web application. This functionality works flawlessly on Google Chrome, Safari, and Edge across iPhone and iPad devices. However, when attempting the same on Firefox for iOS, the downloaded file becomes corrupted and unrecognizable as a .mobileconfig file.

The download mechanism is implemented using a simple anchor tag that points directly to the file on the server. Interestingly, only in Firefox on iOS, the content of the .mobileconfig file gets altered during the download process, leading to corruption.

I'm keen to understand why this issue is occurring specifically with Firefox on iOS and how to resolve it. Has anyone else faced a similar challenge or have any insights on how to ensure the file downloads correctly on all browsers, including Firefox on iOS? Any advice or suggestions would be greatly appreciated!

Thank you in advance for your help!

This is my second email to you....

I just switched to Firefox from Chrome, because Chrome was crashing all the time.

All I want to do is sync my computer, laptop, phone and Ipad's reading list. I want to be able to see an article on one device, add to the reading list, and have it on all devices.

I'm logged in under the same name on all, and it says sync is on, but the reading lists are different.

Can someone help me? My phone number is [removed phone# from public support forum], email is [removed email from public].

Thank you!

Does anyone know what causes Sync to fail in Firefox? I’m signed in on two devices with 6 to 9 tabs max open. My tabs don’t sync or send from one device to another properly. My history also doesn’t work. I just visited a site 2 minutes ago and all I see in my history is sites I visited 12 hours ago. I’m at my wits’ end and ready to find another browser. Please help if possible.

when i have more than 10 pages open the app starts crashing, won't let me go back as well and sometimes just reloads. There were also situations in which he grabbed me without me doing anything. I have about 4-5 extensions (in the photo). I'm using Samsung Galaxy S24, my previous was A52 (I had no problem with it)

no matter what i do firefox mobile says sync is "offline" i did what the troubleshoot page said to do, i deleted and redownloaded the app, i logged out and logged back in three times on both desktop and IOS and nothing is working please help im tired of doing the same thing over and over again for an hour straight with nothing changing

When attempting to sync my data on my android device it doesn't do anything. I'm currently in the account settings on my phone and when I hit "sync now" it just does nothing.

Hi,

This has been brought up before, but not with this exact question (not that I could find, at least).

I understand that cookies cannot be synced across devices, but this is not what I am asking for. Is there a way to make firefox sync the list of exceptions? Meaning, only the specified website URL and its status, not the cookies from these sites.

Firefox on Android has a "Collections" option,it is convenient displaying some websites on the startup page.But "Collections" seems not to be synced.It might be more useful if add the option to Sync List. Or it can be used as a specific section of the bookmark (but displayed on the startup page), similar to the bookmarks toolbar on PC. This makes it possible to sync frequently useful websites on both mobile and PC devices. Thank you for reading this.

I have a question regarding syncing. Is there a way to remotely remove all synced information from Firefox on a particular PC without actually accessing it? For example, if I sync my home PC Firefox with my laptop or my work PC. Then, one day, for some reason I no longer have access to my work PC, and all of my sensitive information is there. Or if I lose my laptop, or if it is stolen... Is it possible to remove all sensitive information from a remote synced PC? Alternatively, is there a way to remove all synced information every time I close the browser? This way I can remove a particular PC in my Firefox account and once the browser is restarted at the remote location, the data will no longer be pulled and synced. Can this be done? Thanks in advance!

Hi, I switched to a new phone recently, and wasn't able to outright sync all of my open tabs from the old device. It was, however letting me access them from the tab menu on my new device, so it wasn't a big deal.

Now I can't see the other phone in the tab menu, just the sync from my PC. I don't have the old phone anymore, because it was a trade in for my current device.

Is there any way to get my old tabs back? The sync must have timed out, because there was no activity for a period of time. I have Firefox synced on all of my devices.

Thank you.

Hello,

I never received a confirmation code to sync with my other computer. I've tried to followed all the instruction per request, still no avi.

I've followed below instruciton from your team:

   Search your inbox for emails from accounts@firefox.com with the subject line "Confirm your account". Be sure to also check Spam/Junk folders.
   Add accounts@firefox.com to your whitelist/address book. After that you, will need to trigger another confirmation email by trying to sign into your account again.
   Check that you’re using the correct email address. Very often the email you’re trying to sign in with is not the email the account was created with.
   If you're using an email application to check your inbox, try using your email provider's website instead, or vice-versa.
   Disable any VPN or special DNS configuration when attempting to sign into your account

Syncing between my desktop and my phone has been working just fine for years, just as it had been with my laptop until recently, but I changed the version of Linux I had installed on my laptop earlier today, and despite being able to sign in just fine (as you can see by me posting this with my account), and it syncing correctly on the initial sign in, actively syncing between my laptop and other devices is not functioning (if I make a new bookmark right now, it will not show up on my phone or desktop).

Looking at the sync page in settings it says "Please sign in to reconnect [my email address]", and the account widget on my toolbar has a yellow triangle symbol and a warning saying "account disconnected", but if I click "connect to another device" on the sync menu and then click "not now" I can get to my account page, fully signed in and able to click buttons to change settings (I signed out my old laptop while I was there just fine).

Attempting to re-sign in by any method (clicking "connect to another device" in the sync menu and then choosing "I already have Firefox mobile"; clicking "sign in" in the sync menu; signing out fully, emptying my cookies etc. and then signing in fresh) all leads me into a loop where I insert my password, provide a verification code from my email, provide my 2-factor code, click "I already have Firefox mobile", and then have to sign in again doing the same steps leading to the same place, forever. I will note, however, that signing out entirely and then signing back in does get me from signed out to signed in despite not correcting this error.

In case it would help I attempted to change my password via the account menu, but it says that my definitely correct password (I used the exact same entry from my clipboard successfully to sign in moments ago) is incorrect, and attempting to use the "forgot my password" menu gives me the error "Unexpected error" instead of doing anything, which is not very helpful. My password remains unchanged. I do not know if this is relevant.

After some looking things up I was made aware of a secret menu called "about:sync-log" which I used to see if I could find an error message, and I did indeed find one (I can guarantee that it's new and relevant because this Linux install is only several hours old).

I don't know how much of this error log is safe to share, so I'll only cut in some choice segments I noticed (which turned out to be, like, over a third of it):

Oh wait, that's the end of the log...

Hopefully this is one of those network errors that just resolve itself the next day and not any kind of serious issue.

Hope everyone at Mozilla is having a good day! (:

I installed firefox on other PC and I logged in with my account. Despite having synchronization for passwords, bookmarks, etc., I can't sync my data on my new PC. Why is that?

Yesterday, I noticed after I closed and re-opened Firefox, my browsing session was completely gone - all my tabs and windows, my entire browsing history, website sign-in status, all completely gone. I've been troubleshooting since then.

I've noticed that the 'sessionstore-backups' folder in my profile folder is missing. When I open Firefox, this folder is created and Firefox writes some data to it, but Firefox seems to delete the folder as soon as I quit Firefox. Firefox should not be doing this. My Firefox is configured to open previous windows and tabs, and is NOT configured to wipe any browsing data of any kind when it closes.

As a sanity check, I spun up a Windows Sandbox (briefly, it's a clean, isolated Windows environment) and installed Firefox there. I also enabled the option 'Open previous windows and tabs'. Firefox behaves normally - it re-opens the tabs/windows I had open when I quit Firefox. Great, that's what I expect. The trouble starts as soon as I sign in to sync. After signing in to sync, and letting the initial sync process complete, I open a couple of windows and tabs, then quit Firefox. Firefox begins nuking my browsing session again - the 'sessionstore-backups' folder is erased, and next time I start Firefox, all my windows and tabs are missing, and my browsing history is missing.

So, at this point, I'm assuming something in my synced data has become corrupt. I haven't installed any new extensions lately. I haven't changed any of Firefox's settings that would cause this to happen. The only thing I have done differently lately was enable Firefox Sync in LibreWolf and sign in to sync there. It seems like this session-nuking trouble started after I signed in to sync in LibreWolf. I assumed, since LibreWolf is a fork of Firefox, and because there were no warnings or indications the feature was incomplete/unstable/experimental/etc., that it would just work, that it wouldn't cause any issues. But it seems like it has caused issues. I checked LibreWolf's issues tracker for anything related to 'sync', but I didn't see anything noteworthy.

I've been using Firefox and Sync for numerous years without issue. This session-nuking thing started yesterday.

I use Firefox in a few places, and based on what I saw happen in my Windows Sandbox, this session-nuking issue is going to happen in every Firefox I'm signed in to as soon as it has a chance to sync. Obviously, I do not want this to happen.

What can I do to determine what the issue is? What can I do to check if something in my synced data has become corrupted? What can I do to reverse it? I'm not opposed to completely wiping/resetting my synced data, but I'd rather not if I don't have to. The only thing I would lose sleep over is my bookmarks, but I know I can export them. Are there any debug logs I can enable/look at? Anything I should look for in Event Viewer?

Thanks.
