1971021 - mobile app uses inexplicably high amount of data

Status: UNCONFIRMED

(Firefox for Android :: General, defect)

Description

[David Park]

Attachment: Screenshot_20250607_204919_GlassWire.jpg

User Agent: Mozilla/5.0 (Android 13; Mobile; rv:139.0) Gecko/139.0 Firefox/139.0

Steps to reproduce:

Used app as normal (largely limited to search engines, news articles, Wikipedia)

Actual results:

Mobile app uses very high amounts of data sporadically (recently 30GB in a day and 15GB in a 3 hour period, multiple instances of 1+ Gb in a day). This has no correlation to my use of the app (amount of time I was on the app, no activity on the app that should use so much data i.e. high quality video streaming, downloads)

Expected results:

Normal use of the app should use ~500 MB per session at most, as has been my experience with other internet browsers.
