752345 - Large Memory Use From ads.lfstmedia.com

Status: RESOLVED INCOMPLETE

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:13.0) Gecko/20100101 Firefox/13.0
Build ID: 20120501201020

Steps to reproduce:

I have left my browser running overnight, and it's memory use is around 2GB.  The biggest source of the memory use happens to be from http://ads.lfstmedia.com/slot/slot5517?ad_size=728x90&adkey=994 

The following potentionally problematic ad-ons installed are:
Download Helper 4.9.9
DownThemAll! 2.0.13
Firebug 1.9.1

There are a bunch of RealPlayer plugins, and there's Quicktime, DivX, WinAmp, iTunes, Java Deployment Toolkit, Nvidia 3d vision and Adobe Flash and Shockwave among the plugins.  I have not tried safe mode or disabling anything yet, to see if this would happen again.  


Actual results:

The memory usage looks to be:

Jasno, Do you still see this issue when using a current version of firefox?

Hello Reporter, thank for reporting this issue. 

I did not monitor or let my system running with Firefox (with this URL) for several hours but I did it for 30 minutes. I didn't see any memory growth with this URL. Memory usage used to go up but the garbage collected used return the memory after a short while.

I tried duplicating this problem on Windows 7 64 bit machine using:

Name 	Firefox
Version 	43.0.4
Build ID 	20160105164030
Update Channel 	release
User Agent 	Mozilla/5.0 (Windows NT 6.1; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0


If you have not upgraded so far, may I request you to try again on the latest FF version and let us know if you still see the problem.

Resolved-Incomplete due to time since last communication/update by reporter.
Please feel free to reopen if the error occurs in a current Firefox version.
