Make option to exclude pinned tabs when clearing browser history on close

[ephemeral]

After having used Firefox Focus on Android, I love the ephemeral browsing idea. On the desktop, however, I often have several tabs pinned (e.g. web mail, cloud storage, calendar) and it'd be great if it was possible to combine the option to 'Clear history when Firefox closes' and have pinned tabs as an option to exclude, so that they are always present when loading the browser afresh.

So maybe something like this?
