On Mac, cannot have Tor Browser and Tor Browser Alpha side by side
On Mac, I can have FF Beta/Dev Edition/Nightly/ESR all as separate apps and run them simultaneously.
I cannot do that with Tor Browser and Tor Browser Alpha.
Even if I rename the Alpha to a different name so they're both in my Applications folder, trying to run a second one says "Tor Browser is already running"
I haven't tried Nightly.
