एंड्रॉयड के लिए Firefox Community Forum

No matter what I do, sometimes, Firefox on my phone won't sync and it's driving me crazy to be honest. I don't know why it happens, it has no fixed schedule and it seems to go away on it's own in a seemingly random amount of time. In this instance, as I'm writing this I've been trying to sync with my PC for over an hour and it simply refuses to sync. I've tried restarting, force stoping , clearing cache.. Nothing. In the past I even tried reinstalling and for it to sync it took a while. I'm lost with this bug and it's been happening for a while now, I was hoping for a fix but so far it seems it hasn't come.

Please let me know if additional information is needed.

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

Hello,

I actually noticed earlier that, on Android, Firefox was saying the last sync was 11 hours ago. I tried to sync but it didn't do anything, as if the button wasn't there at all. I tried restarting my phone, disconnecting firefox on my phone from my computer, disconnecting firefox on my computer from my phone and all these things did was that, now, it says it had never sync.

I'm a bit lost, I didn't find any solution for that.

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

Hello to all. I am writing to ask for help with sync for Android. I have 2 Samsung devices: my S24, which is my phone, and my Galaxy Tab S10 FE+, which is my tablet. I do have an HP laptop, running Windows 11. That device is fine.

I recently noticed both of my devices had the same model # shown up under my Firefox. {it was my tablet.} Idk why. So I read online, that I should sign out, then sign back in, to fix this. So I signed out on both devices, at the same time. I closed both windows, then I restarted both devices, & then signed back in, at the same time. My S24 is fine, but my S10 FE+ is not. It won't sync. So I repeated the same steps with it, and it still will not sync. So I went to my Mozilla Account, then Connected Services, to see the list of devices. I did note a duplicate device, not sure which one. There was no name. I did sign out of it there, but otherwise, everything else looks good. I also pulled up some articles online & troubleshooted, but again nothing. I'm now doing a hard reboot, which is where I turn it off, then wait for at least 5 minutes. Then I'll turn it back on. Nope, nothing. Does anyone have any suggestions as to how to fix this, please? I have no idea as to how to go around the matter by manually doing everything like once a day. I mean, yikes. Thank you for any help, seriously.

Ich bin langjähriger Firefox-Nutzer und habe bereits mehrere Troubleshooting-Schritte durchgeführt. Trotzdem benötige ich konkrete Unterstützung für dieses spezifische Problem.

PROBLEM KURZ: Ich habe ~1.625 Lesezeichen auf meinem Android-Tablet (Gerät D). Diese Lesezeichen syncen NICHT zu meinen anderen Geräten (Windows 11 + 2x Android). Alle anderen Geräte bleiben leer – keine Lesezeichen vorhanden.

GERÄTE-SETUP: - Gerät A: Huawei Notebook, Windows 11, Firefox (neues Profil „CleanSync") - Gerät B: Android-Handy, Firefox - Gerät C: Android-Handy, Firefox - Gerät D: Samsung Tablet SM-X200, Android 14, Firefox (QUELLE der Lesezeichen!)

SYNC-KONTO: - E-Mail: deviation@nickname.berlin.de (Neu erstellt, alte Kontos gelöscht) - Alle 4 Geräte angemeldet + Sync aktiviert - Sync-Einstellungen: „Lesezeichen" ist überall CHECKED ✓

WAS ICH SCHON VERSUCHT HABE: 1. Firefox-Cache auf allen Geräten gelöscht (A/B/C/D) 2. Firefox-Daten auf Android B/C geleert 3. Alte Sync-Kontos server-seitig gelöscht (via accounts.firefox.com) 4. Neues Konto erstellt + sukzessiv alle Geräte angemeldet 5. WARTEN: 2+ Stunden gewartet → Keine Änderung

SYMPTOM: - Gerät D: 1.625 Lesezeichen LOKAL sichtbar ✓ - Gerät A/B/C: 0 Lesezeichen (komplett leer) ✗ - Sync-Status A/B/C: Zeigt „Sync enabled" + letzte Sync vor X Min - → Aber Lesezeichen kommen NICHT an

VERMUTUNG: Lesezeichen von Gerät D laden NICHT auf Mozilla-Server → andere Geräte können nicht syncen

LOGS VERFÜGBAR: - Gerät A: `about:sync-log` (kann Screenshots bereitstellen) - Alle Geräte: Sync-Einstellungen-Screenshots

ZWEI FRAGEN: 1. Diagnose: Was kann ich konkret testen, um zu debuggen, warum Lesezeichen von Android D nicht syncen? (Bitte KEINE Verweise auf FAQ – ich benötige individuelle Anweisungen für dieses spezifische Problem.)

2. Fallback-Option: Gibt es eine Möglichkeit, die 1.625 Lesezeichen von Android D OHNE Sync zu sichern/exportieren (z. B. Datei, SQL-Export, Cloud-Backup)? Ich könnte sie dann manuell auf die anderen Geräte importieren.

Danke im Voraus! 🙏

Why don't you allow me to sync by logging in, I log in, you gave me the second authentication (wooow security) to my mail, I copy and paste it and you proceed back to the login page saying incorrect password. great job at forcing to qr code, congratulations.

Hi

Firefox has stopped syncing from my android phone. In the 'connected services' section of the account page it shows both my PC and phone connected. On the desktop it shows synchronised frequently updating (e.g. 24 seconds ago) but on phone it shows 'never'. It previously showed last sync as 14 days ago but I relogged (from both devices) to try to fix it. It just so happens that 14 days ago I added a new email address to login with my mozilla account (previous email became secondary), but I have checked and both devices are logged in with updated credentials.

Any ideas other than re-install?

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.

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,

For maybe a few weeks, I can't synchronise my account, I've tried to log out / log in multiple times but the "Synchronise now" button does nothing and the "Sync" one on the devices tabs just get stuck on "Synchronising..." but eventually does nothing. I can send a tab to Firefox desktop, but that's all. Both devices are logged on my account. I can't choose what to synchronise because it's greyed out.

Collections bookmarks on the Firefox for Android homepage. I have Firefox sync. I have many regular bookmarks. Collections bookmarks from Android or obviously not available or synced with my Firefox for desktop. Are they synced or backed up at all anywhere? I cannot find them other than inside Collections. If I uninstall Firefox on my Android, Google Pixel phone and reinstall it will everything in the homepage collections be lost?

Hello I am facing a problem hope you can help me. I just factory reset my phone and install firefox again with my account but it didn't access or sync all my saved password.
