Delete History whitelist

I already check FF has one but I’m wanting a whitelist for when I close FF so a few sites like history doesn’t get deleted. doesn’t require your Email to watch tv shows on the site. However I have FF set to delete the session, I have to find where I left off.

I end up have to watch a very annoying number of ADs until I find where I left off.

So I need a way to return to the same place after FF closed.
