Hi FredMcD

Thanks for your suggestions. I've cleared the cache and cookies and maybe that will help.

When checking the security settings, I noticed that with Firefox I'm no longer getting the option to connect to a Teams meeting (as a guest) via a browser, whereas I am in Chrome. See attached shots.

I used to see the browser option in Firefox up until the last week or so. I do sometimes experience websites that don't present properly in Firefox ie buttons not showing etc but this is a new issue with Teams.

Secondly, I've realised I have Firefox accounts linked to two different email addresses. I wondering if being signed into Firefox on say email 1 and then trying to access Teams from an appointment sent to email 2 could potentially cause a connection issue?

Many thanks Catherine

I don't know anything about the 'Teams' site. Maybe others will respond.

If you have the app installed on your computer, you should see the prompt to open the app from Firefox. The website is not for us(Firefox users).  ;-(( see screenshots
