Hello jbnizer,

Your system details show that you have these extensions installed :

Avast Passwords 2.0.4340 (jid1-r1tDuNiNb4SEww@jetpack)

McAfee® WebAdvisor 7.0.0.17912 ({4ED1F68A-5463-4931-9384-8FFF5ED91D92})

True Key™ by McAfee 3.1.0.9211 (@true-key)

Would you please disable them and see if that will make a difference  ?

If it does, and you absolutely need those extensions, you could re-enable them one by one till you find 'the culprit' .....

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.
