I don't think this has to block 49 beta 8. But I think we should fix it before release. 
Is that realistic to do?  Or, should we downgrade to the last version of pdf.js? 
The beta 9 build should start this Thursday. 

Brendan, is this still a project you work on? If not, who would you suggest?

The fix for this just landed on Beta over in bug 1297750. Can you please verify that things work as expected on builds containing that fix? Thanks!

The issue is no longer reproducible on Firefox 49.0b9(20160830170722) tinderbox build.
Tests were performed under Windows 10x64, Mac OS X 10.10.5 and under Ubuntu 16.04x64.

I am not marking this issue Verified Fixed until the 49.0b9 official build will be released. 
Also, I am not removing the ni until the fix will be confirmed on the official build.
