I am running Firefox build 50.1.0 and Evernote Clipper 220.127.116.11 - I have been unable to use clipper since a popup box was introduced as the login default. I put my username and password and the box disappears and the clipper icon remains non-functional. Pressing it brings up the pop-up login .... again and again and again.
I have reinstalled the Clipper multiple times and the problem remains.
Can you please recommend a FIX. I have integrated clipper into my normal workflow and the lack of function is having a big impact on my ability to work effectively.
