It used to work fine, but now (Aug 2021) I get a "reminder" that I need to LOG IN first
.. but I AM already logged in to Pinterest!
Nonetheless, I log in (or at least try to) with each "Save" Pin I try, but loose the pin when I get logged in (again) and am only taken to "new ideas".
This extension has become totally useless after years of working pretty well.
And yes I have cleared my cache and data.. Uninstalled the extension... Rebooted the computer and reinstalled the Pinterest Save Button extension on Mozilla Firefox.
And yet it still works fine in Google Chrome!
