So I had to disable my history deletion on shutdown so Firefox could restore my last used tabs.

Problem: My history doesn't get deleted (automatically).

Is there a way to maintain your last used history so Firefox could restore your tabs after shutdown, but still half clean them automatically? Any "go to your history and click 'delete all' every now and then" is not a solution.

As in: Firefox keeps every open tab saved after shutdown and can restore them again while anything else already closed in the last session gets deleted for good.

Since pinned tabs exist now with vertical tabs, there can also be an extra functionality.
