And whoever told you Edge was not compatible with Jaws is not really telling you the truth.

Almost every browser may have little issues, but you can easily use Edge or Chrome, for me Chrome has been my primary browser probably for about 3 years now. My experience with Firefox has always been more flaky which goes to show how subjective this is, but given the market share Google Chrome has and if you add other chromium based browser it’s even more, this is clearly what the majority of people use and from my observations this is no different among the visually impaired community.
