Add an option to "Close tabs" on browser exit (not after 1 day)

[boricbor101]

Currently the fastest option to auto close all tabs is after one day. I think there should be an option to close the entire browsing session as soon as i exit (close) the browser, just like there is an option for that for most chromium based mobile browsers.

In addition to the author's request, consider closing tabs after night hours. For example, after 5 am, all tabs of the past day should be closed by firefox.
