I am encountering more and more websites with problems they attribute to Firefox. Many of them recommend using Chrome or Edge and some insist upon it or they will no longer support problems. Direct TV will no longer work with Firefox at all and they will not fix it. Several of my other regular websites will work partially, but have pages that simply will not work with Firefox. I have resisted using Chrome or Edge for years but it is getting harder and harder to do as on line systems continue to have problems with Firefox and their only suggestion is to use Chrome (which works when Firefox doesn't). Any ideas/suggestions?
