Attachment: issue.png

Reproducible on Firefox 36 Beta 5 (buildID: 20150129200438)
Mozilla/5.0 (Macintosh; Intel MAC OS X 10.9; rv:36.0) Gecko/20100101 Firefox/36.0

I had several sites opened: Facebook, Youtube, Yahoo Games (https://games.yahoo.com/). I navigated on those sites, I played some Youtube videos, I played some Yahoo Games. After a while, when I was on Facebook page I received the following warning: "Warning: Unresponsive script" - please see screenshot "issue.png". After that, Firefox is unresponsive because this warning message appears continuous. I had to force quit Firefox. 

I had the following error in Browser Console: http://pastebin.mozilla.org/8442572

I don't have proper STR.

Potential major regression

Comment 3

[Benjamin Smedberg]

Since this is mac, the chances of this having to do with protected-mode or sandboxing are very slim.

I reproduced this issue also on Firefox 35.0.1 (buildID: 20150122214805). It appeared on Facebook after about 3,4 hours of using Facebook, Youtube and Yahoo games. 

Also, I want to mention that on Firefox 36 (Beta 5) I used the "Youtube Flash Player 1.2" add-on (to force Flash Player usage on YouTube). On Firefox 35.0.1 I didn't use it anymore, because Youtube still uses Flash Player for that browser version.

I reproduced the issue also on Firefox 36 Beta 6 (buildID: 20150202183609) on Mac OSX 10.8.5 (on a different machine - not the one mentioned on c#0). 
The issue may be caused by the Facebook page because I've reproduced it when I navigated on Facebook and Youtube, but also the issue appeared when I have opened only Facebook page (on a clean profile).

[Sylvestre Ledru [:Sylvestre]]

I had it also under Linux (Debian)

Comment 7

[Lawrence Mandel [:lmandel] (use needinfo)]

Sylvestre - Did we contact Facebook about this issue?

Comment 8

[Sylvestre Ledru [:Sylvestre]]

Lawrence, I didn't because I had the feeling that it was caused by Firefox itself, not Facebook but I might be wrong.
FYI, I didn't see this issue recently.

Comment 9

[Sylvestre Ledru [:Sylvestre]]

Wontfix for 36. I didn't see it and it seems that the issue has been fixed by Facebook.

Comment 10

[Lawrence Mandel [:lmandel] (use needinfo)]

Camelia - Can you confirm that this is no longer an issue?

Comment 11

[Camelia Badau [:cbadau], Desktop QA]

I've tested on Mac OS X 10.9.5 using Firefox 36 RC Build 1 (buildID: 20150219174507) and Build 2 (buildID: 20150222232811) and I can't reproduce this issue anymore.

Comment 12

[Lawrence Mandel [:lmandel] (use needinfo)]

Given that Camelia can no longer reproduce, I'm resolving this bug as worksforme.
