 Hi, I installed torbrowser using torbrowser-launcher on arch linux
 installed via aur.

 Firefox is started by
 TOR_CONTROL_PASSWD=${TOR_CONTROL_PASSWD} ./firefox  --class "Tor Browser"
 -profile TorBrowser/Data/Browser/profile.default "${@}"
 This tries to connect to a running instance of firefox first. If --new-
 instance is added, this could be avoided.

 I don't know my way around firefox very well though, and I can't rule out
 any other communication. --no-remote should stop everything, but if I use
 that, firefox says
 Error: argument -no-remote is invalid when argument -allow-remote is
 so I assume that remote functionality is needed somewhere.

 If this recommendation is not followed, there should probably be a warning
 instead of opening a new, insecure window on the already running firefox.

 Possible duplicate of
 --allow-remote probably because of

 Maybe this needs some more work than just adding --new-instance.
