Great extension!
Just a few questions:

Is there any hope that Mozilla will support this for the new Firefox>=80 on Android?

Why not activly asking users if cookies should be deleted after leaving a site?
Or alternatively making AutoDelete the default and activly asking users if cookies should be kept.

Also has anyone compared this extension with:
https://addons.mozilla.org/en-US/firefox/addon/forget_me_not/
I've been using "Forget Me Not" for about a year and I'm currently trying to evaluate which one may be more suitable for my parents and other less technical experienced people I know.
