Is it possible to edit cookie values in Safari, either by using the Web Developer tool or another 3rd party extension?

1 Answer 1


You cannot use Safari's Web Developer tools to edit cookies (at least not yet?).

Entries in this table are read-only; if you want to edit a cookie’s value, you need to do so with the document.cookie object in JavaScript (you can use the Quick Console at the bottom of the content browser to modify the cookie and see the results update in real time). Pressing the Delete key while a cookie is selected deletes the cookie.
