Issue with Firefox & Microsoft 365

I am no longer able to open a Word document shared with me via Sharepoint in Desktop mode using Firefox. I have received an email from a student, sharing a Word doc file with me. I click the link, and it allows me to open & edit the document online. But, I prefer to click "editing" in the top right and then "open in desktop." When I do this now, I get a message that says "Allow access to Microsoft 365 account. Your browser settings are preventing an optimal experience with MIcrosoft 365. Allow access to improve your experience." There is a button there that says "Allow access," but when I click it, nothing happens.
