Hi @ajk1962f,

I’m sorry for my late response.

Yes—this can be a real difference.

Zoom has separate sign-in “paths” depending on what you’re doing:

Signing in to the Zoom Community/forum: you can be authenticated for the forum site, but that does not always mean you’re signed in to the Zoom Meetings experience.
Joining/starting a meeting: you might be prompted to sign in again (in the browser or in the Zoom Workplace app), and meeting-specific settings can also block joining even if you’re “logged in” somewhere else.

To confirm what’s happening, try this in Firefox:

Go to https://zoom.us/signin and sign in.
Then open the meeting join link again.

If it still won’t let you join, paste what you see on the join page (for example: “Sign in to join”, “This meeting is for authorized users only”, “Please wait for the host”, etc.).

Hi @ajk1962f,

Thank you for reaching out! If you can’t sign in to Zoom in the latest Firefox (and you also can’t type in the post body in Chrome), first confirm whether your Zoom account uses SSO (for example, “Sign in with SSO” / company login).

Are you signing in with SSO (ADFS)?

If yes: a common cause is ADFS “Extended Protection” being enabled. Chrome and Firefox don’t support that feature, which can block Zoom sign-in. The fix is on the ADFS side: in IIS Manager, disable Extended Protection for Windows Authentication on the ADFS site.

Check out this link for more information.

Hello,

Thank you for replying. This time, I was able to log in using Firefox, but I think that this was because I was logging into the forum rather than logging in to attend a meeting. I hope that you can clarify whether this is a possibility.

To answer your question, I do not use SSO; I log in using my username and password.

Any insight that you can provide on this matter would be helpful. Thanks again.

Still waiting for a reply from @aluyun or someone else with knowledge of how to solve this problem. I can’t rate a “best answer” until I get one. Thanks in advance.

You're right—being signed into the Zoom Community doesn't always mean you're signed into Zoom Meetings. Checking the exact message on the join page will help identify whether it's an account sign-in issue or a meeting restriction.
