Firefox for Android Community Forum

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,

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.

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 ?

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 🙏😭.

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?

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.

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

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 reinstalled the Firefox app on my android phone and I am not able to sync the phone now with my account info and bookmarks. Scanning the barcode to sync from my phone does not work. It does not respond at all. Manually entering my email and password does not work either as it says I have the incorrect password when inputting the code sent by email.

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'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.

My account has not been updated since 2023?? Is there something you can do about this? Also there were links I clicked, the questions, and those haven't been updated.

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

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.

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! 🙏

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. 😳
