This test appears to be one of the blockers for migrating browser-screenshots to macosx1014, but I have been able to arrive at a solution via the following:

• disable browser_controlCenter.js
• disable browser_devtools.js
• disable browser_permissionPrompts.js
• disable browser_primaryUI.js

This results in a green mochitest-browser-screenshots run for macosx1014.

Enabling any one of these tests individually would cause the suite to time out at 60 minutes. Longer timeouts do not help, as the suite keeps expanding in time to consume any additional timeouts that are given.

The current proposal is to disable the tests mentioned above, which includes test detailed in this bug, so that browser-screenshots job can be moved to macosx1014 leading to decommisioning of macosx1010 machines.

:pbro - if you have any comments regarding this proposal, please let me know.
