What platform are you on?  Linux?

Comment 2

[Anthony Jones (:ajones, :kentuckyfriedtakahe, :k17e)]

Windows 10. I have a mid-range i3 computer (about 2 years old) and I consistently get the slow script warning.

Comment 3

[Ben Kelly [:bkelly, not reviewing]]

We have logic to throttle timers when in sleep mode.  Its possible that windows 10 is not firing the right event.  I think this is the windows code we get the notification from:

https://dxr.mozilla.org/mozilla-central/source/widget/windows/nsWindow.cpp#5073

Or it could be completely unrelated to this.  Just a wild guess.

+1 here.

I'm on core i7 MBP 2013 and Nexus 6p, in the last month, I see slow script dialogs when I'm in different apps or wake from sleep often on Facebook or Gmail

Jim, Brad, related to the slow script dialog work we did for e10s?

[Wayne Mery (:wsmwk)]

dup of bug 1284511?

Comment 7

[Tooru Fujisawa [:arai]]

Can anyone who is having the issue check the nightly 2016-09-04 with bug 1284511 fix?
I cannot reproduce the issue and cannot verify it.
If the issue is gone with nightly, this is surely the dupe of bug 1284511.

¡Hola Anthony!

Is this something like unresponsive-scripts.png attached?

If so, I also see it on Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0 ID:20161017030209 CSet: 94b0fddf96b43942bdd851a3275042909ea37e09 when a Dell Latitude E6420 with Windows 7 Enterprise resumes from sleep mode.

¡Gracias!
Alex

Tooru - I believe the issue still exists but I will need to double check on the affected computer.

Alex - yes. That is the issue I have been having.

Note that e10s is disabled on my machine because I have a touch screen.
