Need help please to fix this problem: Firefox does not open QR codes on my iPhone. On my phone, the toggle for Scan QR codes is turned on. I open the camera on my phone, point it to a QR code on my laptop screen, Firefox on my phone opens in a new screen -- but nothing happens. What is missing? Thanks for helping me.

Hi everyone,

I’ve been experiencing synchronization issues with Firefox lately.

Current situation: Tabs sync correctly between devices, but bookmarks and passwords no longer sync between my iPhone and my computer.

I’ve also considered an issue with profiles, I currently have three Firefox profiles:

• default-release (currently in use)
• default
• default-release-1

I also used Firefox Troubleshoot Mode (restart with add-ons disabled) to test the issue.

sync-log : The sync-logs show many success-sync entries and only a couple of error-syncs. There are no obvious connection issues (I’m using a shared connection in a rural area). However, bookmarks and passwords are still not syncing properly across devices.

Observed behavior: Sync is active and "functional" Only specific data types (bookmarks and passwords) are affected The issue persists even after signing out and back into Sync, and restarting Firefox on both devices

Checks already done: Sync is enabled for bookmarks and passwords Sync logs mostly show successful operations rather than errors

Hypothesis: A Firefox profile conflict

Question: How can I restore Sync properly without losing my bookmarks, passwords, or other data?

Thank you for your help.

My mozilla account contains history entries from a job a no longer work at.

I've tried deleting history and databases on both mobile and desktop, yet some still persist. I've experienced the issue on multiple devices, making me assume there's something up with the history entries tied to the account.

Firefox on iOS states "No saved passwords" despite my desktop having all passwords and sync turned on. Turning off sync, signing out and back in, deleting the app and reinstall, all did not resolve the issue.

Any help appreciated

I changed the password of my Firefox account recently, which logged me out of my Firefox iOS app. When I'm prompted to scan the QR code to re-establish the pairing, nothing happens. When I choose to use email instead, I get "unexpected error". This happens every time I try to re-pair. Please help me sign in to Firefox iOS.

Yes i tapped sync and on my mac's firefox, the android device is not even shown .. i can see my windows firefox there and see open tabs from there but not from android

why doens't android firefox sync ?

I tried send link to device to device for the first time today from my Firefox for desktop to my iPad. Both devices are synced to the same Firefox account and currently signed in. I get a "Sent" pop-up notification after I do the Send on the desktop web browser, but there is no notification of any kind on the iPad.

My searches for this on the web, and on this site, show me only the 'how to send' steps, and I see nothing that is 'where to look for received links'. What should I expect to see on the iOS device when I do this send?

After the latest Firefox update (ref d49f81), my bookmarks and saved passwords are not syncing. Tried signing out and back in.

Hello. I reinstalled my computer and downloaded Mozilla again. How can I find out what profile I was using before the reinstallation, because nothing has been synchronized in my pana@mail.bg profile at the moment?

Obligatory, I apologize if this question has already been asked or worked out elsewhere. But I have tried searching for a solution on the forums here and not one solution could be found, so here I am:

At the time of setting up my Linux PC for Firefox Sync, I was signed into my Firefox account on my mobile but syncing had been paused on my mobile for some reason or another. No biggie right? Should just be able to enter my credentials into my PC browser and start syncing right away? In the past when I had got signed into sync on the PC, everything across the board would sync as I had just my bookmarks, add ons, and settings set to sync. Bookmarks would load right up, all my add on prompts would open their own tabs to finish setting up, and everything was peachy.

However, when I went to get things setup on my new PC today, using the proper credentials and all kinds of authentication methods, I am able to sign into my firefox account on my PC with no issue, except for the fact that nothing is syncing up with my existing mobile account.

I have done everything I know that is in my power to do, with the exception of reinstalling my mobile app (will lose my bookmarks if I do), I have uninstalled and reinstalled on my laptop, signed out of both devices and signed back in with my account credentials to no avail. I went so far as to just create a new Firefox account with a separate email address, and using the NEW email address when signed into both, I am looking at the "Sync Now" button on my mobile with hatred, because clicking on it literally does nothing. It shows as last synced being "Never". My PC is logged in to Firefox now with the new email address and clicking sync there, it will run through the normal process but as there seems to be no data coming from my my mobile, it syncs nothing. I can see both devices under "Connected Services" as well.

I know I screwed up somewhere and now the entirety of my life's favorite bookmarks and websites are stuck on my phone. To my understanding there is no JSON style file created in Firefox mobile, with no ability to manually export. I am not above manually going line by line through each bookmark and just adding them one at a time into my PC, but I would rather not.

In summary:

- PC is not syncing to mobile bookmarks which are very much still in existence - Creating a new Firefox account and restarting the sync process from scratch does not work - As of creating and logging into the new firefox account, clicking sync does absolutely nothing on mobile, and still shows as having never been synced

I've recently upgraded from an a34 to an a56, both phones running the same build of Firefox, both signed into my account however the old phone can see the tabs of my laptop and the new phone, the new phone can't see anything. I'd like to be able to port the tabs over ideally.

Also of note is the tab view is totally different between the two phones in layout too.

I'm at a loss as to how I can painlessly move over the tabs.

After the latest Firefox update (ref d58ebe), my bookmarks and saved passwords are not syncing. Tried signing out and back in.

Hi! Today I synced a tab from my Android device to a desktop PC. The link arrived successfully, but on the Android device many many inactive tabs disappeared without a trace(searched history, recently closed etc.). looking up about:sync-log I only got txt files of errors, no trace of links. Can you help me get back my closed tabs? TY

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.

I wanted to synch my current settings in my browser to import them on my new laptop. When I tried to login to my account, I the message from the attached screenshot appeared. So I created a new profile, got my stuff back to what it should be and then deleted the "new" profile. But now every time I try to get into the correct profile and login into my account, I still get the message from the screenshot. I never ever synched with another profile before and never had an issue in the past. Right now I am rather pissed off, because I lost atleast some of my bookmarks during this whole ordeal.

Hi there,

Firefox desktop and Fennec Android are syncing everything perfectly, including tabs from Fennec in Firefeox, except for when I try to view tabs from Firefox in Fennec I get the message: "You don't have any tabs open in Fennec on your other devices".

I have tried to figure out what's causing this and have searched for answers but I can't figure it out. Could anyone suggest what the problem might be please. Appologoes if this is something obvious I've just missed.

Many thanks,

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?
