Firefox for Android Community Forum

I was using Firerox Beta on Android and yesterday or for the last couple days my Firerox account would keep getting logged out as in I'd have to sign in again and again to sync or send tabs to other devices. (It would repeatedly say sign in again to sync even after I sign in repeatedly).

I uninstalled Firefox Beta and installed Firefox stable on Android. No such issue so far.

For years, I've been using FF on desktop (Linux), tablet (Android) and phone (Android - Samsung S24+). Sync has never been a problem until two weeks ago when FF on the phone has either refused to sync when I tapped the command, or hasn't synced for many hours or sometimes days (which is why I tried to do it manually). So, I signed out of my FF account on all 3 devices and then signed back in. The desktop computer and tablet are syncing normally, but the phone still won't sync. When I tap the 3-dot menu on the phone and then my name, it says the phone has NEVER been synced and tapping the sync command does nothing. Under "Choose what to sync", all options are checked, but greyed out. Can't change them, in other words. When I access bookmarks on the phone, it properly shows what was there before the last sync. The phone is running FF version 150.0 Build 2016155439

Help!

syncing bookmarks between Android Mobile and desktop through shared Mozilla account, but the bookmarks from mobile aren't appearing on the desktop. I can see that both devices are logged in, but cannot see bookmarks being shared.

please, there isnt a "sync and save your data" option!! there is no qr scanner or use email instead prompt. just that MOCKING little "sync now" in account settings that does nothing!! PLEASE

I have tried using the account menu to find "sync and save" in response to the prompt for the QR code on my desktop. There is an option that says sync but when I click it it does not open up a QR code reader.

Hello everyone, my name is Francesco and I have a big problem that I can't solve in any way! I just can’t seem to solve a synchronization issue between two Firefox 135.0.1 (64-bit) installations on a Laptop and a PC (both running Linux Mint 22) and a Firefox 135.0.1 (Build #2016074239) on Android. Can someone please help me? I'm desperate!

Let’s start from the beginning: For a very long time, every time I connected to the internet with Firefox on my Laptop or mobile, my bookmarks would get completely messed up: folders duplicated endlessly, some empty, others identical to the original ones. The same happened with the bookmarks themselves: separators almost all moved to the bottom and multiple duplicates of my countless bookmarks.

After several failed attempts following posts from other users who had the same or a similar problem, as well as some Firefox support how-tos, I decided to try a different approach, which was also described in a post.

First, after logging out of my account on all three devices, I backed up my bookmarks from my PC in different formats (.html, .json), and after closing Firefox, I also backed up the cookies.sqlite, favicons.sqlite, and places.sqlite files—just in case! Then, I deleted all folders and bookmarks from the other two devices.

I then spent the whole afternoon cleaning up my bookmarks on the PC: removing duplicates and redundant folders, organizing separators and bookmarks the way I wanted, and making new backups as mentioned above. After that, I logged into my account from my mobile, triggered a sync from there, then logged into the other devices and started the synchronization on them as well.

But it didn’t work. 😞

PC and Laptop synced beautifully, everything was perfect, but the mobile, despite showing that it was syncing, remained empty—and still is.

I tried several forced sync methods as suggested in some Firefox how-tos (https://support.mozilla.org/en-US/questions/1482205 and https://support.mozilla.org/en-US/kb/how-set-firefox-sync-firefox-android), and I also followed procedures from other posts where users had similar issues, but nothing worked.

I even tried different approaches: logging out and back in first with my PC, then with my mobile; replacing all bookmarks with the ones I had exported in good condition; checking if there was a new update on Google Play. But my mobile remains completely empty—no bookmarks at all.

So, after more than four hours of trial and error, I'm losing my mind 🤯, and I’m also getting seriously exhausted (it’s now 2 AM, and I’ve been up since 5 AM!).

Does anyone have an idea on how to fix this? A plugin? A folder on the mobile where I can manually place the saved files? Maybe a well-aimed hammer strike in a specific spot on the phone? Anything? At this point, even just a good joke might help me get through the frustration. 😜

Now, I just hope I can get some sleep—I’m so stressed that… 😭

Best regards to all, see you next time, and... good night!

P.S.: Sorry for the long post. 😳

Both the phone and tablet are current gen and both up to date. I do not have the computer anymore as it was left behind when my child and myself escaped a domestic abuse household permanently. I was not about to haul a computer on a last minute escape. I changed passwords, etc. Keep getting "something went wrong" when I go to firefox dot com / pair. I need my phone shit synced to my tablet.

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.

Please help 🙏😭.

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! 🙏

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,

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.

Добрый день. У меня всё было хорошо, и ранее с телефона всегда были доступны синхронизированные вкладки, которые открыты в браузере на ПК, однако недавно мне понадобилось разлогиниться на телефоне, потом я снова залогинилась, и с тех пор у меня возникла с ними проблема. Вкладки просто пропадают сами по себе спустя время. Чтобы они снова появились, мне нужно оказаться у своего домашнего компьютера и открыть Firefox, и осуществить синхронизацию (если она не успела произойти автоматически). Тогда какое-то время эти вкладки появляются в Firefox на моём телефоне с Android,.. а спустя время снова пропадают. Это очень неудобно, потому что я не могу, находясь на работе или в поездке, комфортно воспользоваться вкладкой, использованной на домашнем компьютере. Раньше эти вкладки были доступны всегда, и я всегда была спокойна и уверена, что могу к ним обратиться. Что делать? Помогите, пожалуйста. Прикрепляю скриншот, где видно, что вкладок нет (к сожалению, сейчас не могу сделать скриншот, где они есть, поскольку в данный момент времени я нахожусь на работе).

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.

Hello,

I sorted out my passwords for several reasons in Firefox on one device and want it to synchronize with my other devices.

Whatever I try, the passwords stay the same on my other devices. I have checked and unchecked the password synchronization box, I restarted, I even deleted the app and reinstalled, but when I sign in, it still has the same passwords.

This took a loooong time.

Why is the password synchronization not working and how can I fix this?

Thank you.

Trying to sync my samsung to my windows PC and there is no "sync and save data" button. I went to my account and to sync settings and then pressed "sync now", but still nothing happened

hello

I had a smartphone, it died I bought a new one

I moved the SD card from the old to the new one, dear stupid Android 13 then 14 say: oh I'm sorry you have to format your SD card, lol

during the configuration of the new smartphone, I asked to restore data from the backup of the old smartphone: - some parameters has been restored - applications were reinstalled - for example osmand restart with all configurations made on my previous smartphone

but, when I run Firefox, even after login on firefox sync, I have ......... nothing: - no passwords - no bookmarks - no preferences

why?
