Thank you for your response. I've been using EvernoteClipper on firefox for years. I tried using Safari when it wouldn't work on Firefox. It's doing, or rather not doing a variety of things, none of which are helpful. Sometimes it simply won't work, or it's got these cross-hair, drag to define your clipping window, but nothing goes to my Evernote account...etc.
Does it look and work like it did before this change a few weeks ago when after Catalina was installed? Or was it an upgrade? or both?
I'll get a support ticket, thank you.
