Tor Browser on OS X doesn't open the link after it launches
When Tor Browser is set as the default browser on OS X, and isn't already open, and I click on a link, it doesn't open that link. Once it has launched, it opens subsequent links.
A simple workaround is to never close Tor Browser, or to click on the link again after it finishes opening.
I think this happens because the "open" event (containing the link) gets sent to Tor Launcher, which doesn't send it on to Tor Browser.
This happens in both Tor Browser 5 and Tor Browser 5.5.
