Hi,

To that end, I have a habit of using your System Monitor/Resources/Network History to monitor my “sent” and “received” data. As you may know, the data sent when browsing is normally just a small fraction of data received, maybe 10%.

For example, if I visit Amazon.com and browse 46.3 Mb worth of pages, then exactly 46.3 Mb of data is ALSO added to the outgoing data total. Why?? I am very concerned as to why my incoming data would need to be mirrored ANYWHERE, and am hoping you can tell me why I should not be worried about it. I’ve been using Tails for years and Tor Browser has never acted this way before, and fyi the Unsafe Browser is not affected by this, only Tor. As a work-around, I’ve been using Tails 4.19 to avoid the apparent “mirroring”.
