Symptoms

In Safari 7 or previous versions, links in the development panel in JIRA 7 are failing. These errors are found in JavaScript console:

TypeError: undefined is not an object (evaluating ‘window.performance.now’)

Or:

TypeError: undefined is not an object (evaluating ‘window.performance.now’)
h
f
JIRA.DevStatus.CommitView._onSummaryLinkClick (anonymous function)

dispatch
i
TypeError: undefined is not an object (evaluating ‘window.performance.now’)

JIRA.DevStatus.BranchView._onSummaryLinkClick (anonymous function)

Cause

The 'windows.performance' object is not supported in Safari 7 or lower.

Resolution

Safari 7 is not a supported browser in JIRA Cloud. Check this documentation for the supported browsers: Supported browsers.

Upgrading to Safari 8 (which is supported and supports that object) or using a different supported browser is necessary.
