> lets you fully erase your browser history for any website

I just want a button to whitelist a domain and an option to automatically clear 100% of everything outside the whitelisted domains on every restart.

And always clean the cache, perhaps even for whitelisted domains unless the system is on a metered/slow connection.

Also, every website should always be opened in a separate "container" so cross-site tracking won't work.

If Chrome did that today this would trigger a cascade of consequences. If Firefox did that today it would just improve Firefox popularity and cause no problems.

As a number of people above mentioned, Cookie AutoDelete extension for FF does exactly this.

Sites start out default clearing all cookies the moment you clear the tab. Greylisting clears them when you close the browser. Whitelist retains all cookies.

Multi-account Container and Temporary Container extensions take care of your per-tab container needs.

Although I use Cookie AutoDelete and open GMail (which I didn't whitelist) in a separate container, GMail still remembers me somehow. I have to manually go and clear all the saved data in the Firefox settings to actually reset everything.

It sounds like you're hitting a Firefox bug affecting Cookie AutoDelete. Something about the recent changes to cookies has prevented extensions from clearing partitioned cookies.
