Server Version#:4.57.4 Player Version#: Firefox version 89.0.1 MacOS 11.4 With the latest update if Firefox I can not log in Plex. I get an error when trying to log in. See the screenshot. I am storing cookies and I can log into plex using safari with no issue. I have always used Firefox until now. Does anyone have a thought. ![image](https://global.discourse-cdn.com/plex/original/3X/1/b/1b65fb7986a46d2e969b3b0fc14c86026f8db6c0.jpeg) ---
