I am setting up new laptop running windows 10. I have installed Firefox browser several times with same result. Once installed Firefox will not launch reliably. If I restart computer, firefox will sometimes launch. Very frustrated, have used Firefox for 10 years on several machines with no issues. I am running Firefox 96.03 on a different laptop with no issues. Can I upload an older version of Firefox on my new laptop or can you help me fix the new version so it will work?
