a site i have been accessing with no problem for years is now NOT ALLOWED after the latest firefox update. the last update started giving an insecure web site notice , now in all their wisdom it will not permit access. firefox is getting very close to the recycle bin. how do i undo or revert to previous versions.

The problem you are seeing is caused by either Avast or AVG, do you have them installed?

My honest suggestion is to uninstall Avast or AVG, as what they are doing is putting your internet connection at risk. The built in Windows Defender is a better security than Avast or AVG, and doesn't do these shady things that make your connection worse.
