Browser Toolboxfails to open when tor-launcher is present
In latest dev branch origin/tor-browser-60.8.0esr-9.0-1 the Firefox chrome debugger ( enabled in about:debugging -> Enable add-on debugging ) does not launch. When you attempt to launch it ( via Menu -> Web Developer -> Browser Toolbox OR via Ctrl+Shift+Alt+I key combo ) the tor-launcher dialog pops up claims that it cannot connect to Tor, and the permission dialog asking whether you want to allow the local debugger to connect never appears.
Building firefox with --disable-tor-launcher in your .mozconfig does allow the debugger to work.
