Another solution to try is quitting and restarting Firefox.

Can you post a link to a publicly accessible page (i.e. no authentication or signing on required)?

You can remove all data stored in Firefox from 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 from this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data from 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 from that website will be saved once again.

I was just trying to post another solution response since mozilla had the earlier questions marked 'archived'.

I see. Archived just means that the post is over a certain age.

Also, please mark your https://support.mozilla.org/en-US/questions/1252663#answer-1203886 response as Solved Problem using the link to that message's right.

I am sure that others can gain from your post.
