Where exactly are cookies stored on my device, and can I manage them? or How do I find out where cook

Pro tip: Cookies where stored are *usually* in %AppData%\..\Local (Windows) or ~/Library/Preferences (Mac).

But tbh, browser settings are way easier. Safari? Preferences > Privacy > Manage Website Data—clean and simple.

For advanced control, Cookie Quick Manager (Firefox add-on) is clutch. Lets you sort cookies where stored by site.
