How to end process while quiting, Firefox 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
The regular Firefox for Android is not a privacy-focused browser, it's a general purpose browser with (IMHO) the best privacy defaults that balances privacy and day-to-day usability, but it's not meant for high privacy.

You should use Firefox Focus instead, which is actually designed to be an incognito browser. Additionally, if you really need the highest level of privacy, you should be using Torbrowser.
