What I want to do is limit the cookies that are allowed to the sites that I visit the most, then delete the rest on browser exit. That way, I get logged in automatically to my favorite sites, then f* the rest of those cookies. My plan is to: 1) Manually delete all cookies, 2) Quickly visit and sign in to all my favorite websites, 3) Add permissions to allow only those cookies that were added, 4) Then set the "Delete cookies and site data when Firefox is closed" checkbox Unfortunately, there is no easy way to do 3) because the Manage Data and Manage Permissions dialogs don't talk to each other. It would also be nice to be able to specify a domain or general expression for allowed cookies, such as *.bankofamerica.com I guess what I am asking for is better tools to add allowed cookies from existing cookie lists instead of the very blunt tools we have today. I am using Firefox v 75.0 Thank you.
