You appear to have a user agent that is modified by Avast Anti-Track that could be causing problems, so if you do use this software then try to disable it. You will have to contact Avast about this if their software causes problems for you. We can't do much about this apart from identifying Avast Anti-Track as a possible cause.
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.
