I would really like to use this as my primary browser, unfortunately Atlassian's login flow doesn't work in this browser. I suspect it is actually Atlassian at fault here but since I am forced to use Jira for work I have no choice.

Can you try setting "content.cookies.accept" to "all" instead of the default "no-3rdparty"? If that doesn't help, can you set with --temp-basedir?
