Hi,
Firefox does not starts (normal, esr and even developer edition) if Tor browser bundle started already. It gives already another instance running error.
Thank you

Tor browser is Firefox inside with a few configuration changes bundled with Tor. They changed the icon, but it's still Firefox including Firefox.exe running.
Sometimes, the impossible can become possible, if you're awesome!
