Firefox has a quit button in it's menu. My settings are check marked to clear all data upon closing. However, quitting Firefox is still leaving the process running and the cache non-empty. So to really quit, I have to: Settings | Apps | Firefox, then tap 'Force stop' and 'Clear cache'. I end up doing this a couple times a day. A couple times a year I mistakenly tap 'Clear data', which is disastrous because settings and add-ons are lost.
The mozilla website maintains that stopping and clearing are OS tasks. So here I am.
How can I, an end user, stream line this? perhaps configuring the OS to end the process when the firefox quits?
Short of that, is it possible for an end user to add to the homescreen a shortcut to: Settings | Apps | Firefox
