I have tried several times to sign in to my bank with my Firefox browser, which I use all the time for the same function. However, this time I keep getting an Access Denied message. This seems to be particular to Firefox, as I have been able to log on using Chrome with no problem.

Please explain the problem in detail. What happens? What is/are the exact error message(s) ?


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.
