Don't wait for Tor to start
If communication between firefox.exe and tor.exe was intercepted for some reason during start, then
The error message "Could not connect to Tor control port." is displayed after Tor Launcher (part of Tor Browser) fails to connect to the Tor control port for 30 seconds. But it usually happens when security suite asks users for permissions for these applications. And often 30 sec are not enough to create rules. So, Tor Launcher needs an option to manually continue the startup process instead of showing "Waiting for Tor to start...".
