User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36 Steps to reproduce: Re-run my attachment from Bug 1304165, firefox-rollback-crash.js: https://bugzilla.mozilla.org/attachment.cgi?id=8795574 I know this bug was fixed at one point, but it appears to have regressed. The crash log even indicates a very similar (same?) error in the code. Take a look at this, for example: https://crash-stats.mozilla.com/report/index/36a5fc89-4dec-42ec-977e-db3ee2170222 I hit this bug again on accident, before realizing it essentially reduced to my previously-posted bug. Actual results: The tab crashes. Expected results: The tab should not crash.
Here is a slightly different reproduction example where Firefox offers fake audio and video: https://jsfiddle.net/c1h8sx4m/4/
Sorry, I take it back! I should've read more carefully (it gets confusing jumping between browsers). I said "I know this bug was fixed at one point", but that point must have been when I was testing with Firefox Developer Edition. I reviewed the previous rollback ticket, and see its target is marked 52. I retested both with 52 and Developer Edition and see things are OK in those releases.
