User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:68.0) Gecko/20100101 Firefox/68.0
Steps to reproduce:
Activate data on my android phone.
Actual results:
Firefox downloaded once 600 MB, once 1,15 GB without any interaction in the background.
The second time, the 1,15 GB, were downloaded
Expected results:
It should have downloaded some Megabytes.
Somebody else had this issue, that's why I'm finally reporting it.
I am deeply concerned as to how this occurred when my phone screen was off and I wasn't using it.
It's potentially costing Firefox users quite some money, so investigating might be worth it. I will do what I can to help.
The other person asked in form of a question on Firefox Support.

On 4/30/19 between 8:15pm and 8:35pm, when I was not using my phone, I received notices from Verizon that I was almost out of data, then out of data, and finally that I was being charged $30 for data overages.
When I checked to see what app had used this data, Android indicated it had been Firefox. In the time listed above it seems Firefox somehow used something in the range of 5 - 8GB of data. Being that my phone screen was off, no videos were streaming, and no downloads or uploads were happening how is this possible??
Verizon has refused to provide answers as to how that level of data was utilized in such a short period of time. They indicate they are only able to tell me it was Firefox that was using it.
I am deeply concerned as to how this occurred when my phone screen was off and I wasn't using it.
This is not to mention the $30 in overage charges I am now being charged as a result.
I would like to know a) what was the content of this huge data spike that occurred via Firefox on 4/30/19 between 8:00pm and 8:40pm b) how did it happen while my phone screen was off? c) what kind of resolutions can Firefox provide regarding my data overage charges.
I saw the same issue twice.
First time Firefox Background activity ate like 600 MB of my data while I was browsing. I suspected some service workers updating their caches for shit I wouldn't even look at.
Now I had reset my phone, and re-setup everything. I forgot to restrict background data usage for Firefox on metered connections.
The very same day, I stayed online when leaving the WiFi. After an hour or so, I recived the text that 75 % of my data were used.
It happened before, so I checked Firefox background usage, and it was at 1,15 GB in one or two hours.
In Firefox, no service worker was registered, and not a single tab was open! I had just reset the phone, so I can quite certainly rule malware out.
Can we rule out Firefox Sync? How much data is plausible to be exchanged?
