 I noticed that there is a reproducable Bug (at least on my PC) with Tor
 Browser v3.6.5 (latest version as of 2014-09-06).

 If I open and close Tor Browser a few times, it always get into a state
 where "firefox.exe" is running in the background, and you click on the
 icon, but nothing happens.

 Sometimes, it pops up dialogue box "Firefox is already running, but is not
 responding. To open a new window, you must first close the existing
 Firefox process, or restart your system."

 If I manually kill the "firefox.exe" process, then everything starts to
 work properly.

 In the short term, I would suggest that you enhance this error message, so
 instead of telling you to "Close the existing Firefox process" (which
 might be difficult for someone like my Mum to understand), it offers to
 automatically fix the problem, which is a matter of killing the process
 "firefox.exe" and retrying again.

 Environment: Windows 7 x64, latest service packs.

 p.s. In this ticket, I couldn't fill out "Milestone", "Version" or
 "Compnent" as it didn't mention "Tor Browser v3.6.5". Might want to fix
 this.

 p.p.s. Tor Browser is awesome in every way, it is an incredible service to
 help people living in oppressive regimes who like to shoot people for
 posting their thoughts online.
