Anyone who uses Firefox on Windows knows the browser has an almost insatiable appetite for memory, and it's not unheard of for PCs to allocate a half GB or more of memory just to the browser alone. Mozilla continues to deny that Firefox leaks much memory, but Christopher Blizzard, a member of Mozilla's board, says fixing the issue is a priority - - especially now that the browser developers are seeking to plow directly into the mobile space. Writes Blizzard:
"As Mozilla starts down the path to running in the mobile space we are spending time looking at memory pressure issues more closely. . . (I)t sounds like the early data suggests that Mozilla really doesn't leak that much memory at all. But it does thrash the allocator pretty hard and that's what causes the perception of memory leaks."

and will fix it finally
of course it wasnt until everyone made noise about it that they did anything about it
People have been unhappy about this for years and it hasn't been fixed; whether things turn out differently this time remains to be seen.
I prefer Opera, notwithstanding some individual's opinion.
Something wrong with your setup methinks.
It's actually called Firefox Ultimate Optimizer, but you were half right...unfortunately it is an Adware program!
Yeah sorry
Do a search, you'll come across many forums that people have reported there adware/virus/malware scanners reporting it as the following:
AdWare.Win32.FireOptimizer.b
Search on the aforementioned Adware:

What they are admitting to is a performance issue, not a memory leak.
Firefox uses an average of 43 MB on my machine.
Do you think I care?
I personally use Opera on a daily basis. I find it uses less memory, works with all my sites and loads pages much faster.

Well, I never denied it, it's a pain sometimes...and to let you know I am not a fanboy; I use Firefox & MSIE, and the same goes for Windows & Linux.
If I am a fanboy of anything, it's Technology.

'nuff said.
All these are on a fully patched Win32 XP SP2 Pro machine with 2GB RAM.
Browser Fresh 18Tabs
IE7 --------- 32MB -- 123MB
FF1.5 ------- 18MB --- 60MB
FF2 --------- 20MB --- 68MB
MyFF2 ------- 68MB -- 120MB
FF3 --------- 31MB --- 65MB
Opera9.24 --- 18MB --- 74MB
MyFF2 = As a web developer I use alot of extentions, MyFF is my setup of FF which has 47 active extensions installed, 1 theme, 8 plugins and a bookmarks file of 1.2MB.
Task manager Mem Usage, should I be using something different?
Had myFF running all night now, with the 18 tabs open some with ajax on them, 47 extensions some that refresh like forecast fox, gmail manger etc etc and the memory usage in fact has gone down a small amount to 118MB. So maybe one of the extensions you have installed is not working too well.
if you leave firefox open on a page that contains AJAX that refreshes a portion of the page it will just keep taking more and more memory
I'm sure it would be easy enough to throw together a proof-of-concept to demonstrate this; my code isn't doing anything special, just repeatedly grabbing a set of values and creating HTML elements to display them.
Something people aren't mentioning in the above reports, but which might be quite significant, is their cache settings. The client machines in the above example are on default settings (50MB disk cache), but at home I use zero cache and the memory leak on the same site actually isn't quite as bad. Why's that then?
If there is something they should invest in is working on more stable builds for Linux. In my experience at least, Firefox is much more stable on XP or Vista than it is on Linux (even without plug-ins or extensions enabled). It would also be nice to see a good x64 build that was official (i.e. better support for extensions and plug-ins).
Looking forward to Firefox 3...
Granted I have 103 Tabs open; but when i close and then start again with the same 103 tabs its around 200 MB. So somewhere 403 MB appear. Sounds fishy, I definitely think there is a leak.
