Didn't realized that. My currently employer is MS-stack based so I have been working with Edge and to be fair, this was also surprising. I would probably rather work with Firefox but the browser is not that intrusive and provide the same level of support and tooling I get with FF. I think one the reasons I decided to stick with Edge these last few weeks is the extremely poor support I get when working with the SharePoint implementations that are for internal use, seems to be a issue with the way FF interacts with Windows Authentication.
