Hello, Working with a coworker to try and fix an error: Something went wrong We couldnt sign you in. Please try again. Issue type: Unknown Issue. I already checked firefox updates, cleared startup cache, tried in troubleshoot mode, disabled addons, tried a different windows account, tried in a private window other Microsoft apps work just not Sharepoint it gets stuck in some kind of sign in loop. The credentials work fine on my computer. Would Firefox not work like that if the computer time was off? Only thing I can think of.
