When I chose ebay.com the cursor in the tab just keeps going back and forth but never completes the page sign on. After 3 days of the same result, I tried using MS Edge and it worked loading the sign on page and I put in my ID and PW but it sensed I was a "new" computer and wanted me to call ebay to process the "new" computer usage. I didn't want to change to Edge, so I just stopped the process and chose to write to you to get FF "fixed" to keep using as usual.
