Gmail "Unable to connect"
For several weeks now, my ability to access my Gmail accounts on Firefox has been spotty. Sometimes it works, but sometimes it doesn't. It'll go from working just fine, to saying it's offline and telling me it's "Unable to connect." No other sites — even other Google sites, like Drive or Sheets — do this, just Gmail. And I'm able to access it just fine in Safari and Chrome. Help?

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