User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:41.0) Gecko/20100101 Firefox/41.0
Build ID: 20150929144111

Steps to reproduce:

Playing a Flash-based game, several other tabs open.


Actual results:

Prior to FF 41.0.1, FF would freeze during the occasional Flash-based game, owing to high memory usage.
The current release would freeze often during Flash-based games, with no pattern recognizable or certain action made.


Expected results:

According to FF 41.0.1 release notes, hanging issues ought to be solved by now with Flash plugins running.

Can you reproduce the problem in a brand new profile with just one tab open?

I see a lot of complaints about this in Army of Awesome written in Japanese. So, I believe that we have something new regression in 41. One tweet claimed that when he/she downgrade his/her Firefox to 40, the hang-up isn't reproduced. And somebody said that this is reproduced in any websites which use Flash Player. And also this feedback (https://input.mozilla.org/ja/dashboard/response/5632397) claims that this is reproduced with new profile.

Unfortunately, I cannot reproduce this bug, though.
I can reproduce this problem on my PC.

I am able to run successfully by installing the firefox-41.0.en-US.win32.installer.exe. 
xul.dll also contains.
Please try clean install or custom install to another folder.

It was caused by AntiVirus software. xul.dll is removed by Norton Internet Security.
After restoring xul.dll, it seems to work fine.
According to comment 6 and comment 9, your try build works well. I hope that it'll be fixed in 42 Beta. Could you take this bug?

[Tracking Requested - why for this release]:

I see a lot of users who complain about this bug in Army of Awesome even only with Japanese tweets. So, not fixing this bug may make more damage to our marketing share. Fortunately, looks like that Aaron Klotz [:aklotz] has a patch for this bug.
