On a daily basis there are intermittent differences in controlCenter screenshots between Nightlies with the controlCenter panel appearing at a different height. This is the one of the two common intermittent failure with Nightly comparisons which make be hesitate to enable emails alerts.

This has been going on for months now but I am just getting around to setting up automated alerts in bug 1331211. On today's Nightly comparison[1] the following images were affected: > == osx-10-10 == > controlCenter_36_darkLWT_mixedActiveUnblocked DIFFERENT (8870) > > == windows8-64 == > controlCenter_15_noLWT_mixedActiveUnblocked DIFFERENT (2278) (attachment 8827284 [details]) [1] https://screenshots.mattn.ca/compare/?oldProject=mozilla-central&oldRev=5ce3882eec21be3a70e4afc050959ca2f76bfa76&newProject=mozilla-central&newRev=8eaf154b385bbe0ff06155294ccf7962aa2d3324&filter=%5E%5B%5El%5D.*controlCenter_.*_mixedActive

Mass wontfix for bugs affecting firefox 52.

I feel like I haven't seen this in the known intermittents recently (though I could have missed it). Maybe bug 1009116 fixed this? I'd like to try and remove the rules from known_inconsistencies temporarily.

Seems fixed.
