Intermittent "no internet connection" from only Yahoo Mail. All others connect OK. Does not occur in MS Edge. Occurs randomly--two maybe three times a day sometimes more. Goes away randomly, but sometimes I must restart Firefox to make it go away. While it's happening with Firefox, I can access Yahoo Mail with MS Edge. I've tried to disable addons and plugins, but no improvement. It's been happening for about three months + or - a few months. (I've used Firefox since almost forever.) This problem is nasty!

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
