Intermittent denial of access to favorite sites
Why does Firefox sometimes deny me access to two of my favorite sites as below...seems to happen every am, but not late in the day?

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
You can remove all data stored in Firefox for a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").
Using "Forget About This Site" will remove all data stored in Firefox for this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data for that domain that you do not want to lose then make sure to backup this data or make a note.
You can't recover from this 'forget' unless you have a backup of involved files.
If you revisit a 'forgotten' website then data for that website will be saved once again.
Your urls are both 'http'. Do you have 'HTTPS-Only' in your Options (Privacy & Security page)?
