Closing a window while importing bookmarks crashes Tor Browser
If one closes a window (e.g. the browser console) while bookmarks are imported the browser crashes. This does not only happen with chrome windows. A window opened by a content script causes the same (although that is of not so big concern right now as we open it in a new tab automatically).
This is no genuine Tor Browser bug but is visible in the latest Firefox Nightly as well.
