1. Go to
2. Scroll up and down through the page for like 10-15 sec

The browser becomes unresponsive and after some time of unresponsiveness the following error is displayed:

"A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue.


1. Pressing to stop the script doesn't solve the issue.
2. This issue is not reproducible with dom.ipc.plugins.asyncInit set to false
3. This issues is reproducible on FF 40 DevEdition

This is the NPN_Evaluate hang.

Wontfix for 39; I think since we're turning off async plugin init for 39 maybe this won't be an issue for 39 anyway.

Assigning to Ben because all tracked bugs should have an assignee. Feel free to re-assign to whoever necessary.
Assignee: nobody → benjamin
I'll take it.

status-firefox39: wontfix → disabled
Now this one is harder to repro; I think that changes to the embedded Flash content (ie, different ads) is the reason why. I'm working with the other bug that is duped with this one and seeing some results, though.
Aaron - What's the status of this bug? Did you have success in the other bug? (bug #?) Is this now resolved or a dup?
