Firefox uses GBs of data in background
On three nights, while I was sleeping, firefox burnt through 0,5 to 1GB of data of my cellphone data usage plan. Although this was reported as a bug four years ago, the issue is still open. See https://support.mozilla.org/en-US/questions/1274045 And https://bugzilla.mozilla.org/show_bug.cgi?id=1273552 And https://bugzilla.mozilla.org/show_bug.cgi?id=1565475
I appreciate Mozilla/Firefox, but this is unacceptable. It is costing me €15 in three days. And that money isn't even going to Mozilla but to my data provider.
I need to voice somewhere that this gave me serious reason to consider dropping the use of Firefox mobile. The above thread provides a workaround, but this shouldn't be solved by a workaround; it shouldn't happen period.
