Set up a framework to fully man-in-the-middle my own browsers' networking and see what they're up to beyond just looking at their DNS queries and encrypted tcp packets. We force the browser to trust our mitmproxy cacert so we can peek inside cleartext traffic and made it conveniently reproducible and extensible.

It has containers for official Firefox, its Debian version, and some other FF derivatives that market a focus on privacy or security. Might add a few more of those or do the chromium family later - if you read the thing and want more then please let us know what you want to see under the lens in a future update!

Tests were run against a basic protocol for each of them and results are aggregated at the end of the post.

Posting with ambition that this can trigger some follow-ups sharing derived or similar things. Maybe someone could make a viral blog post by doing some deeper tests and making their results digestible ;)

if you remove mullvads vpn app what do you see?

Assuming you mean the Mullvad extension (which is installed by default in MB) and not the Mullvad VPN app (which also exists but never came close to these machines) :)

That will indeed likely make a difference on Mullvad Browser numbers. However for now I'm not changing the "keep addons at stock defaults" invariant or the test matrix might get really out of hand.. Should we disable uBlock Origin in LibreWolf? How about uBO or NoSccript in Mullvad then? Konform Browser loads uBO but only if its apt package is installed; should we do that? What happens when we try to explicitly opt out of everything under Preferences in Firefox? I guess the last one is something to actually consider but for now not touching the addons.

(Would be super cool if anyone else tries this out and reports back though! The compose should hopefully be straight forward and easy to get started with if you are on Linux and have podman available. The report mentions it TL;DR we had to work around the oBO install in LW not properly utilizing the proxy (?) like this and I think same approach could be used to Uninstall Mullvad extension from Mullvad Browser and prevent it from even loading)
