 We plan to abandon our first party isolation patches and use those in
 Firefox 52 instead. While the behavior should not change I think we should
 make sure that this is and will (for the future) be indeed the case. I am
 not so sure about the best way to achieve this, though. Is it just a
 matter of running our tbb-tests as soon as we switched to ESR52? Or can
 and should we do more?
