On 9/29/2024 my sign in to icloud to use mail worked fine. Monday 9/30/2024 the mail loaded but didn't work correctly. Prior to Monday, I could right click and select a delete, move, or whatever. I could open the email and the options were available just above the mail. If I use other browsers, edge, chrome, opera, etc it works great. It doesn't with FF(my preferred browser) I do not think this is an Apple issue. I've uninstalled and reinstalled icloud and reinstalled FF. Didn't uninstall it and lose all my data. I've added icloud.com to allowed list. Still doesn't work. I need help.
