I had my local supervisor of elections webpage opened up (votealachua.com) in Firefox in the background. I clicked on an NPR link in Facebook. When Firefox opened up I got this pop-up on the votealachua page "You need to read the comments at the top of this JS file and define some things before calling this script" I have got this message from this page once before, but I am not sure how to trigger it. I tried to replicate the exact same issue from today. I had a votealachua tab open, and I went in Facebook and re-opened the NPR link, but I did not create another popup. I am using uBlock Origin. I was wondering if this is related to that.
