- I was unable to reproduce this crash on Firefox 46.0a2 (2016-02-09) and Firefox 44 Rc build 3 (I only encountered Bug 1243309). But, based on Breakdown of total crashes per product and version list, I see that Firefox 46.0a2 and Firefox 44 are affected too.

Is this a Firefox crash, or is it just the plugin that goes down? The crash reports are a bit all over the place. A plugin shouldn't be able to crash Firefox, but we're unlikely to investigate if the plugin itself is crashing.

It is reproducible in aurora when multi-process(e10s)is enabled. If e10s is disabled,the page does not crash.
