 It takes too a long time for Tor Browser to close and be ready for a next
 start

 Operating System: Ubuntu 18.04 64bit
 Tor Browser ver: 9.0.5 64bit

 When closing Tor Browser i have to wait about 70 seconds for it to close
 completely.
 For instance, when i start the browser and do nothing (but leave it on the
 initial page "about tor") and then close it, it takes a while for
 processes "-childID 1" and "-childID 2" to close, but the process
 "-childID 3" (or, in the case of surfing, usually the last in number) as
 well as "Firefox" remain in the background of processes for nearly 70
 seconds (or 1 minute and 10 seconds) - in that time the process "Firefox"
 is working intensively taking most of the processor resource (over 98%)
 (i.e. for all that time - about 70 seconds - until it is completely
 closed).

 It is impossible to start the browser during those 70 seconds (you know
 the message "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.")
