The Firefox start page comes up fine but when I try to go to another website I get a massage that the site is not secure. This applies to all sites. I have Google available and I can go there to view all these sites but Firefox has all my bookmarks, etc and is much handier-- if it works. I've re-booted the computer as well as the 4G hotspot so this isn't the problem.
