Thank you in advance for your help! Background: I use FB container, do not have a FB account (although did several years ago), and have other privacy add-ons through Mozilla. I have 'high' security settings. Issue: When I am asked to create an account using an email address - the FB container pops up and indicates that if I use my 'real' email address (I have a few on different services) - FB can track me. Note that FB container does not pop up when using other sites where email accounts are required. Question(s): Can FB track me even though I don't have a FB account? Even if I use an email alias - am I still protected from FB? I looked at Relay - but it looks like it needs access to your computer and complicated. Thanks again. You are a great team of folks who volunteer.
