Put sessionstore.js in profile folder and try to restore the session in FF. It will take a lot of memory in Win7 x64 and less than 1GB of RAM in case of XP 32 bit. ALso the attached PNG file shows your possible URL that may leag to wasting at least of 1.5Gb of this amount of RAM.
Severity: normal → major
Could you post the log from about:memory?verbose (type this in the location bar) when the memory use is important. Did you try in safe mode to see if the issue comes from an add-on? https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

Now regarding safe mode. When I ran FF in safe mode it took pretty moderate 400Mb without any attempt of bloating. But when I opened this URL:http://www.google.ru/url?sa=t&rct=j&q=&esrc=s&source=web&cd=5&ved=0CE0QFjAE&url=http%3A%2F%2Fblogs.flexnetconsult.co.uk%2Fcolinbyrne%2F2008%2F02%2F26%2FPowerShellSharePointThreeWaysToDeleteAListItemIDCAMLStringMatching.aspx&ei=CQLYUIC1IIX74QT8mYHIBA&usg=AFQjCNEfzv-rcEOk1hYk1JtDoZA-mmi0Yg&bvm=bv.1355534169,d.bGE&cad=rjtit started inflating very quickly and crashed after taking about 3Gb.
Flags: needinfo?(senglory)
Visiting that link even on 32 bit made firefox eat up wast amounts of memory and even after closing the page will firefox remain highly unstable with a few seconds of no cpu usage then go to 100% with rapid surges of memory allocated. The instability can be described as following: 1. Tab closed 2. memory drops to 1.7GB 3. CPU rise to 100% blocking the main thread 4. Memory starts being allocated to 2.08GB 5. CPU drops to 30% on firefox 6. Memory drops to 1.7GB 7. wait ~10 seconds repeat 3-7 Nothing can be done while firefox is getting its main thread blocked
The question still open. How come the main thread gets blocked? And how to avoid this case?

First, its expected that 32 bit will use less memory than 64 bit because pointers take half the size. The blog page linked works just fine for me. I don't see any slow script dialog or high memory usage. Has the page changed? Can you still reproduce this problem?

FWIW, the Link in Comment 3 still kills today's Nightly as described. The direct Link without Google.ru is WFM.

When the slow script dialog fires: Hit JavaScript "debugger" keyword. JS call stack... 0 highlightWord() ["http://blogs.flexnetconsult.co.uk/colinbyrne/2008/02/26/Powe rShellSharePointThreeWaysToDeleteAListItemIDCAMLStringMatching.aspx":172] this = [object Window] 1 highlightWord() ["http://blogs.flexnetconsult.co.uk/colinbyrne/2008/02/26/Powe rShellSharePointThreeWaysToDeleteAListItemIDCAMLStringMatching.aspx":156] this = [object Window] 2 highlightWord() ["http://blogs.flexnetconsult.co.uk/colinbyrne/2008/02/26/Powe rShellSharePointThreeWaysToDeleteAListItemIDCAMLStringMatching.aspx":156] this = [object Window] 3 googleSearchHighlight() ["http://blogs.flexnetconsult.co.uk/colinbyrne/2008/02 /26/PowerShellSharePointThreeWaysToDeleteAListItemIDCAMLStringMatching.aspx":209 ] this = [object Window]
So the page has a script that only runs when the referrer is google.
This is a site bug. It extracts the search term from the google referrer URL and tries to highlight it. In this case the highlighter searches for "" because of the "&q=" bit in the URL. <arbitrary string>.indexOf("") always returns 0, so the script ends up ilooping. The site has the same behavior in Chrome.
