Is this a limitation of Safari/MacOS?
I also found this: https://support.sweetpproductions.com/topic/346/cookie-5-scripts/3
Is not being able to view session cookies another limitation of the browser/os?
@nate it is technically possible to edit cookies in Cookie, I just haven't implemented the ability. In the 8yrs I have been working on Cookie, you are only maybe the 2nd or 3rd person to ask for the feature. So its not really a priority for me to implement.
the cookie script isn't needed on Mojave anymore, as Apple has changed how the cookie storage works. This change also affects the effectiveness of removing cookies while Safari is open.
Session cookies aren't visible externally for any browser as far as I know.
