Although uBlock Origin is available for Microsoft Edge, it doesn't work right with Edge. As far as I know, it only works right for Chrome and Firefox. I am using Firefox 64.0.2 as I write this.
Am soo glad to be rid of that pesky , bouncing upand down red banner!!
AND - while I was in the process of getting rid of it - I discovered an unwanted extention that had snuck in,, so I removed it too. It was called FromDocToPDF.
This page is soo much cleaner and easier to read now!!
