Build ID: 20121128204232

Steps to reproduce:

Started using and started playing one video in firefox 17 version under Windows OS 64 bit

Actual results:

AFter the 5 mins video ends, i checked the memory consumption in task manager which is huge as 470 MB and the adobe flashplayer memory consumption has been more than 100 MB which is always unusual. If i keep it idle, the memory consumption keep on increasing till 600 MB sometimes and the CPU gets running faster

Expected results:

The memory consumption should be nominal and as low as the previous releases of Mozilla firefox like 15 and 14.  Also the memory leak problem should be found out and solved for idle tabs.

Could you test with a fresh profile, please:

In addition, try with Hardware Acceleration disabled (

Loic, those aren't really useful data points. We want this to work whether or not acceleration is enabled.

madsamy, what version of Flash are you using (from about:plugins)? Is it possible that you upgraded Flash recently?

Since different youtube videos use different playback mechanisms, can you paste the exact video you are using to test?

Also pasting information from about:memory might be useful in diagnosing whether this is a leak, "normal but large" memory usage, or something else.

Hi Guys,
Thanks for the replies. But i do not have the same setup as i had before.

1. I have cleared the profile and created a new profile just after a month.
2. I have cleared the cache folders many times.
3. There were some upgrades from firefox which have been done automatically in between. 

Hence, i am not sure whether my current setup would help analyzing this issue.

With the current setup,i am getting 300 MB usage of my memory and Adobe consumes around 100 MB which i think still a huge amount. If you want, i can play some videos and get back to you with the info tat you have asked for.
