P.S.I had not opened up Firefox APP in awhile, but just tried, and went to our Medical Clinic site, where a small balance is due, but I wait making them send the paper bill since my wife does not do things like that online beyond her IPad emailing & Texting, looking up recipes, etc. So if I dropped dead today, she would not be aware of any E-bills.

Anyway, the Med site opened fine, so I assume that the Firefox APP is kept current update wise, with Google Play auto updates, thus remaining secure, even beyond EOL.
