Clean up the mess and quit! This extension brings back the good old quit button to life as well as the ability to clean what you wish at the same time.
You can select what is going to be deleted as soon as quit is pressed via the add-on options.

There is a known Firefox bug that affects this and other add-ons.
If on your Android device, under Settings -> Developer Options, you have "Do not keep activities" selected / checked, Firefox will lose add-on menu items ... Uncheck that option, to solve that problem :-)
