Hi Brave folk,
I’ve become a big fan of the Self-Destructing Cookies add-on for Firefox for cookie management. SDC allows me to not only disallow third-party cookies, but control and white list first-party cookies as well. For most sites, I just let cookies destruct when the tab is closed. Some sites need to have the next level up, destruct when the browser exits. Lastly, for sites I trust, I allow cookies to persist.
Please have a look at Self-Destructing Cookies if you’re not familiar with it, and consider a similar cookie management option for Brave. I’d like to see options in the Default Shields: All Sites preference settings and Site Shield pop-up for a specific site to choose the three options of destroy cookies ‘after tab closes’, ‘when browser exits’, or ‘never’.
