i could not play or displeasure videos, they were gray and would not play. I disabled every thing and sill nothing, but bookmarks tab was empty but still a folder in Bookmarks. Uninstalled Firefox reinstalled and now i get the "Your connection is not secure" on major sites that I use many times a day. These include Yahoo, my.yahoo.com, Facebook and the download page for Firefox. had to use Edge to download Firefox.
