When I was using Chrome I would get this message on some web pages they wouldn't open they would say I needed to download a web browser set it up and install it all right now that I've downloaded Firefox I'm still getting the same message sometimes what do I do to fix that message what am I doing wrong?

For sometime now I have been unable to access my Bell email on Firefox except if I use private browsing and then it allows me to get to my login and by default allows me to enter my login and password. But if I don't use privacy browsing mode, I cannot get to my email. This is on my android Samsung phone btw. Bell tells me it's a browser issue and that I'm to contact Firefox or switch to Chrome or Edge, but I'd rather do it through Firefox. Can anyone assist as to how I can correct this issue?
