Comment (by gk):

 Suppose I am starting Tor Browser, check the "Request another bridge"
 option, press Cancel (to think a bit more about it or for whatever reason)
 but click on the "Request a bridge" button pretty shortly thereafter I get
 greeted with
 {{{
 Tor Browser is already running, but is not responding. To open a new
 window, you must first close the existing Tor Browser process, or restart
 your system.
 }}}
 and I get an error about meek and handshake failure. That alone is pretty
 confusing for a number of reasons ("Hey, I don't want to open a new
 window, I want to get bridges!1!!" "Why the heck should I need to restart
 my system here just because I want to get bridges??" etc.), especially as
 I see the CAPTCHA in the background showing up. What's much worse, though,
 once this happens is that I can't get a single new bridge that way without
 restarting my browser session. I always get that error (and during the
 whole time my computer is pretty busy).

 I think we should try to handle this case more gracefully. Ideally, I
 think meek would be shut down again if I clicked the `Cancel` button
 (assuming that's not happening at the moment and the underlying issue).
