Load the web page. Then, to reload the page bypassing the cache and force a fresh retrieval; Ctrl+Shift+R (Mac=Command+Shift+R)

Try this several times.

While this works for the first page, when I go to the next page, I have to do this all over again. So click to page 2, CTL-Shift-R, click to page 3, CTL-Shift-R, click to page 4, CTL-Shift-R, etc Highly annoying and unworkable. This worked fine on versions 82.0.0 and less. 82.0.+ introduced the problem.

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.

Thanks. I will give this a try on my test machine as I don't want to reinstall/upgrade on this machine until I know the solution works.
