Extension requests expose Firefox's minor version and custom app name
Original report: https://github.com/mullvad/mullvad-browser/issues/386.
Basically, MB uses a custom user agent in requests started from extensions, such as:
Mozilla/5.0 (X11; Linux x86_64; rv:128.0) Gecko/20100101 MullvadBrowser/128.5.0
It doesn't happen on Tor Browser, because we don't customize it, but I think it'd be okay to include such a fix at the Base Browser level.
STR:
- open the browser inspector
- set it to multiprocess
- go to the network tab
- open uBO settings on filter lists
- force the update of a list
- check the user agent in the inspector
