I was asked what error message I get when trying to browse company web sites using Firefox 58.0.2 64 bit. I do not get any error message. The web site just doesn't respond when trying to place an order. I call the various companies and have been told that at least these ones I had dealt with will not work properly with Firefox. It is the way they have set up their web site, to work only with IE and Chrome. I was asked about Add-Ons. I have Ad-Blocker and Norton Security. Those are the only add-ons I have enabled on my browser. I cannot do anything to get the company web sites to work any better with Firefox if the web sites are set up to NOT work with Firefox. I only asked what Firefox/Mozilla is doing to make itself more friendly to corporate web sites?
