Remove the need to click OK when connecting to the remote debugger

[kumar303]

Since web-ext is a development tool, it only adds friction to the process when you have to click OK in Firefox to allow the remote debugger connection. @rpl has an idea for using an add-on to disable this prompt :)

@kumar303 I took a rapid look and the good news is that now it is much more simple than in the past:
we can just use an existent preference, isn't it great? :-)

NOTE: this will be even more important if we want to run integration tests around the "run auto-reload" feature on a build machine.

We looked at this the good first bug triage and we felt it probably wasn't a good first bug.
