Zendesk has been like this for me since forever. Every time I need to use it to talk to a vendor, I roll my eyes for 2 seconds and open my backup browser which does not have 3rd party cookie restriction.

Could you please file a bug and provide steps to reproduce the issue? I'm happy to take a look. You can file it here: https://bugzilla.mozilla.org/enter_bug.cgi?product=Core&comp...

When I was blocking 3rd-party cookies on Chrome, I couldn't log into the IRS site. I figure that might happen here, too.

Can concur, this broke Zendesk integration with Jira so I had to disable it for our Jira setup.

EDIT: Nvm, I found it. Thank you.
