Haven’t almost all browsers always had this feature in the form of “keep until browser is closed” or “delete local data after closing the browser”? At least Firefox and Chrome have it hidden somewhere in the settings.

right, right! forgot about that since (as sibling post says) I never close my browser. and since deleting all cookies on browser close is super aggressive and painful.

i'm referring to the latest safari which tracks 3rd-party cookies and deletes them automatically after 24 hours if you've never sent that cookie as a 1st-party one. thus effectively eliminating tracking, yet allowing sites to work normally without having to temporarily enable various trackers or determine which ones are "safe".

at the same time, google/chrome said they are taking a different approach which still allows tracking. i'm not sure that they said they would NOT CONSIDER implementing a feature like safari's though.

When was the last time you closed your browser?

On a desktop, every time I wonder why I am running out of RAM or why my CPU is max-ed up.

Do you close all the tabs that could have tracking elements? If not, session restore preserves the cookies.

I set the browser to flush all site data every time it closes.

I use an extension called the Great Suspender. It auto suspends pages on unused tabs. I REALLY like it.

Ich close it every few hours.

It’s a Firefox extension.
