Some of users are experiencing small annoyance when using Jira macro in Confluence. They are using Mozilla Firefox -browser and for some reason, when they add https:// -link for Jira issue, it doesn't auto-resolve to Jira macro. Link stays as an normal www-link.
Macro works perfectly when they add {jira:key=ABC-1234}. I believe this is something to do with their browser settings, because when I am adding https:// -link, it autoresolves correctly.
