this is a very low volume crash signature appearing in firefox 53 with MOZ_RELEASE_ASSERT(!mThrottleScheduler.IsScheduled()).

Comment 1

[Chris Pearce [:cpearce (Not reading bugmail)]]

We have reports in 53 only. The calling code in 52 is different, so this problem may just go away in 52. We should continue to monitor the crash reports in 52, and otherwise do nothing to see if this passes.

[Emma Humphries ☕️🎸🧞‍♀️✨ (she/they) [:emceeaich] (Pacific Time) use needinfo]

This is an assigned P1 bug without activity in two weeks. 

If you intend to continue working on this bug for the current release/iteration/sprint, remove the 'stale-bug' keyword.

Otherwise we'll reset the priority of the bug back to '--' on Monday, August 28th.

[Randell Jesup [:jesup] (needinfo me)]

No reports other than 53.
