Bug / feature request

1. Firefox ESR Portable cannot start after Tor Portable

I see this as a bug because I can start Tor Portable AFTER I start Firefox ESR but not the other way around.
Firefox detected there was another instance of Firefox running and failed to start.
Tor portable do not have this restriction. Would the development team please port the relevant code from Tor to fix this please.

2. "Firefox Portable.exe YourURL" not working
Again traced to the "bug" that firefox detected another instance is running and failed to load, when I only wanted to open URL in a new tab from Windows Explorer without starting another firefox process.
