Recieving 403 messages on 2 websites that are used often.
All of a sudden - Both of these websites below give me 403 errors. I cleared the CACHE, rebooted, checked the other settings - Nothing has been changed and I have the most recent FF version installed - 84.0.2 Also both of these can be accessed from any other browser - so it must be a FF issue.
I have used both sites for a long time with no access issues.

All help appreciated! JM

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.
