I lost them on my Mac book laptop days after activating synch on my android phone too. Luckily i found how to restore them, but the experience made me turning it off. The way how they are synched should be much clearer.

Witam, chciałbym zgłosić bardzo nietypowy problem z przeglądarką Firefox na Androidzie. W nocy z 18 na 19 października (około 23:00–6:00) przeglądarka Firefox zużyła 49,6 GB danych komórkowych, mimo że telefon był zablokowany, a ja spałem.
Nie miałem otwartych żadnych kart wideo, nie pobierałem plików ani nie używałem aplikacji. W statystykach systemowych (Android, sekcja „Zużycie danych”) widnieje informacja, że:
dane w tle: 49,59 GB,
dane w pierwszym planie: 14 MB.
Wersja Firefoksa: 144.0 (Android)
System: Android 11 RKQ1.200826.002
Telefon: Redmi K20 Pro Professional
Konta Firefox są zsynchronizowane z komputerem.
Nie mam zainstalowanych nietypowych rozszerzeń.
Załączam zrzut ekranu pokazujący zużycie danych.
Czy możecie pomóc ustalić, co mogło wywołać tak ogromne pobieranie danych w tle? Czy to mogło być np. błąd synchronizacji, cache lub jakaś aktualizacja PWA / service workerów?
Dziękuję z góry za pomoc!
Pozdrawiam, Tomek
Hello, I’d like to report a very unusual issue with Firefox on Android. During the night from October 18 to 19 (around 23:00–06:00), Firefox used 49.6 GB of mobile data, even though my phone was locked and unused.
There were no videos, downloads, or active tabs running. According to Android’s data usage details:
Background data: 49.59 GB
Foreground data: 14 MB
Firefox version: 144.0 (Android)
System: Android 11 RKQ1.200826.002
Phone: Redmi K20 Pro Professional
Firefox account is synced with my desktop browser.
No unusual add-ons are installed.
I’ve attached a screenshot showing the data usage statistics.
Could you please help identify what process could cause such massive background data consumption? Maybe a synchronization loop, cache download, or PWA / service worker issue?
Thank you in advance for your help!
Best regards, Tomek

When scanning the QR code, my phone is stuck on this: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-10-12-17-54-22-6b261a.png While my desktop shows this: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-10-12-17-55-00-1c9ca2.png
When signing in with email on my phone, I get an "Unexpected error": https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-10-12-17-56-18-5c7b93.png
I've tried everything. I've cleared the app's storage and also re-installing the app. I've removed the old device login from "Connected Services" in https://accounts.firefox.com/settings.

The tabs don't regularly sync between the desktop and Android browsers. I can manually hit the "Sync now" button on either end, and the latest tabs open don't change. Specifically I can't sync tabs opened on the Android browser to the Windows desktop browser. Clicking the button on the desktop browser does something, it switches to "Synching" with a loading throbber, but the tabs don't appear below in the list. Doing it on the android browser does nothing, it still reads "Last Synced 12 Hours Ago" on my android browser, and this is generally the number it says, more or less, whenever I attempt this.
I've tried updating the browser on both devices, and force stopping it on the android device and restarting it based on community recommendations, then reattempting to sync, and neither helped.
Other options suggested copying sessionstore.jsonlz4 from the profile folder on one device to the profile folder on the other device to transfer the open tabs (https://support.mozilla.org/en-US/questions/1404630), but the guidance to do that doesn't work on Android, as it lacks the menus referred to in those guides. I don't know how to access the session data on Android, nor could I find a guide for it.

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.

Sync was working great across multiple devices, which was the main reason to choose Firefox actually. Then, two days ago it just stopped. No device was syncing the tabs on the other ones. I had to add the devices again, losing all synced tabs in the process.

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.
