Yeah, looks like a regression. I cannot reproduce this on Beta, but not so on Aurora. I'll test this with mozregression tomorrow.

Oh, I got different stack with Aurora...

Oops, my beta was too old, but it was a good hint.

Unfortunately, when I type "good" or "bad" after this test, the Nightly process hangs up. Therefore, mozregression doesn't work perfectly, so, I'm not sure I can find the regression cause.

Due to bug 1110018, I cannot build inbound builds locally... Sigh...

FYI, This also affects Flash Player.

I recently random experience this crashes when playing Flash Player video and minimize the Firefox window, I will cannot restore the window, and the Flash hang popup.

On Windows 8.1, Fx39b, whichever the dom.ipc.plugins.flash.disable-protected-mode be false or true.

Comment 8

[Ryan VanderMeulen [:RyanVM]]

Does this still reproduce for you?

Comment 9

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

Oh, I can reproduce this bug with neither Firefox 41.0.1 nor Nightly (44).

I think that it's different bug because I've experienced this bug only on the specific website. (i.e., I couldn't reproduce this bug with other websites.) So, this must be caused by that website accessing plugin with JS or something.
