Hi, I have an email with links to documents stored on MS Team (https://teams.microsoft.com/...) and I get the following error return by the MS site when I try to open it in Firefox (Version 63.0 (64-bit) ):

D'oh! To open the web app, you need to change your browser settings to allow third-party cookies.

I added https://teams.microsoft.com to the following list of exceptions: - Block pop-up windows - Cookies and Site Data

I even tried to disable the "Third-Party Cookies" options: it still doesn't work.

If I try to open the link with Chrome to confirm that the link is valid, it does work.

Does that happen if you use IE or Edge?

I just tried on IE Version 11.345.171340 and it does work.

Also of interest, when I open a link to a MS Sharepoint document from Firefox, it DOES work. Only links to MS Team documents, which are really stored on Sharepoint at the end - MS Team is just sitting on top of MS Sharepoint for file storage -, DO NOT work.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block (wanted) content (Adblock Plus, DuckDuckGo Privacy Essentials, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block (wanted) content.

Firefox shows the shield icon at the left end of the location/address bar in case Content Blocking is blocking content.

  • click the shield icon for more detail and possibly disable the protection

You can check the Web Console about what content is blocked
