Extremely high memory usage after upgrading to Firefox 12
After I upgraded to Firefox 12, I began frequently experiencing Firefox memory usage ballooning extremely high (2-3GB after a few minutes of light browsing). Sometimes it will drop back down to a more reasonable level (a few hundred MB), sometimes it hangs (presumably while trying to garbage collect everything), and sometimes it crashes. Usually the crashing thread cannot be determined, but when it can be, it is in the garbage collection code ( https://crash-stats.mozilla.com/repor.../list?signature=js%3A%3Agc%3A%3AMarkChildren%28JSTracer*%2C+js%3A%3Atypes%3A%3ATypeObject*%29 ).
I was able to capture an about:memory report when Firefox had gotten to about 1.5 GB and have attached an image.
A couple of things I've tried. I have lots of tabs open (though the Don't load tabs until selected option is enabled), so I copied my profile, kept all my extensions enabled, but closed all my tabs. I then left a page open to http://news.google.com/ and it ran fine for several days, whereas my original profile crashes multiple times a day.
I also tried disabling most of my extensions, leaving the following extensions that I refuse to browse without:
Adblock Plus BetterPrivacy NoScript PasswordMaker Perspectives Priv3
However, the problem still happened in that case.
Don't know if any of this helps or not. I'm looking forward to trying Firefox 13 when it comes out.

Never did find out what was causing the problem, but since upgrading to Firefox 13, the crashes and pathological memory usage have gone away.

hello, thanks for reporting back with detailed information.
from a brief look at your extensions i don't recognize any known (to me at least) memory leaking ones. in the last weeks there were also reports about the java plugin causing high memory consumption in combination with firefox 12 - in case you have it installed in firefox > addons > plugins try disabling it for a few days & test how firefox is behaving with many tabs.
& although probably not related to the memory problems you could update your graphics driver to get better results with hardware acceleration in firefox - this is the latest driver by intel for your model & os: http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=21135...
You could still try to run Firefox for a while without any extensions to see if it helps in any way.
