Description

5 years ago
User Agent: Mozilla/5.0 (Windows NT 5.1; rv:17.0) Gecko/20100101 Firefox/17.0
Build ID: 20121128204232

Steps to reproduce:

On some websites plugin-container file handle count increases without end until the system crashes. The handle count can be monitored with task manager with the appropriate columns turned on. This can be repeated at one website: www.xtube.com.
Open several videos in new tabs and then once the videos start pause them. Then watch the file handle count run out of control. Not sure if this is a JAVA issue or something else. It seems that Firefox is not handling what some websites do on their websites very well. 

OS is Windows XP SP3


Actual results:

System becomes very sluggish and eventually will crash unless firefox is closed.


Expected results:

File handle count should not run out of control.

Sorry, accident caused from doings things from a mobile.
The plugin-container is mostly a slim shell for plugins like Java and Flash. Do the same sites leak in Chrome or Opera?

Internet Explorer 8 does not leak on the same sites that Firefox leaks on.
Internet Explorer uses a different plugin architecture and hence not the same plugins.
As the site uses Flash, Opera can be used for comparison (Chrome ships with a different Flash plugin).
Summary: on some websites plugin-container has too many file handles that continue to increase without end.hout → plugin-container file handle leaks on some sites using Flash

I'd like to find time for somebody to try and reproduce this; if it shows up, it shouldn't be hard to figure out what kind of handles we're leaking and whether this is a Firefox bug or a Flash bug.

Greg, did you notice any non-xxx site where this can be reproduced?
