Lost Mozilla as my default browser after accidentally opening my Facebook page using Edge. The only site that is corrupted is Facebook. All others work properly. I still want Mozilla. Looks like I've created a newer Mozilla account even though I used my password to open my account using my email address and password. My profile name has changed. Wondering if problem occurs because account is shared with my husband and our account is under his name/email. Any suggestions appreciated. We do subscribe to Norton. Thanks.
