We have recently migrated to the new Kanban board in JIRA 6.3. I've noticed that when someone else modifies a ticket, the board view updates automatically on my Chromium / Ubuntu 13.10, but not on my Chrome / Win 7 or Firefox / Ubuntu 14.04. All I get is a pop up in the bottom right prompting me to refresh the page.
What's the mechanism controlling the refresh? I would like automatic refresh enabled across all my platforms.
