When I close the browser, recently it is leaving a lot of background processes running. As a foreground application, when I close the browser, I want it ***closed***. That is, no remaining processes/services. File|Exit should mean exactly that. @Mozilla, please fix this, or add a very clear/obvious setting in Tools|Settings for "Close all browser processes/threads" on exit. I shouldn't need to get into about:config to start finding things to disable. This has been interfering with backups because of files remaining open/locked even after the browser is closed.
