When landing bug 1711822 I had to increase the values in browser_preferences_usage.js to stop it failing. I'm pretty sure the increased usage is because of the CSS applied to tabmail, and I think I can do that a different way to fix the problem, but I want to check it all works properly first.

This fixes the performance regression after bug 1711822 by avoiding a lot of unnecessary layout calculation.
