Comment (by arthuredelstein):

 Many thanks to rustybird, Giorgio and intrigeri for your work on this!

 Replying to [comment:26 rustybird]:

 >  in the unlikely case that the NoScript WebExtension finishes startup
 sooner than the unbootstrapped XPCOM Torbutton extension

 Do we know for sure that NoScript loading first is unlikely? I'm not
 actually sure about what determines the order of XPIs loading.

 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.

 Giorgio, would that sort of patch sound reasonable to you? If so, I can
 send a pull request.
