Implement better communication between NoScript and Tor Browser
While preparing the Tor Browser 8 release we ran into a number of issues with communicating with NoScript and getting the Security Slider to work (legacy/trac#26520 (moved), legacy/trac#27401 (moved), legacy/trac#27411 (moved)). We should implement a better approach for communictaion. The currently best plan is outlined in comment:33:ticket:26520:
If we wanted to be absolutely sure, NoScript could be patched to listen for a "ping" and reply with a "pong". And then torbutton could repeatedly send "ping" (say, once a second) until it receives a "pong", and then proceed by sending the first updateSettings message.
