Tor Browser is writing to Windows registry on every start
I got a report from a cypherpunk:
https://gitlab.torproject.org/tpo/applications/tor-browser/-/wikis/Platform-Installation
Firefox is still writing to Windows Registry on every start:
Computer\HKEY_CURRENT_USER\SOFTWARE\Mozilla\Firefox\Launcher
There it stores all the paths TBB was started from.
That also allows an attacker to permanently disable Launcher Process
security feature, and even any hiccup can do/leads to it:
