Windows 7: firefox eating 480 MB of memory?

I have no plugins and firefox exe only uses 35 mgs with one window and 70 with 4 windows open

I think I was using a lot of plug-ins when I took that screeny, like noscript, flash, flashblock, addblock plus, xmark and auto pager.

now I moved to 7264 x64, and running Minefield 3.0.10 which is the 64-bit firefox project mozilla are working on , so far so good. just running noscript, xmark plug-ins atm. here is a screeny of process memory usage:

so it's seems to be taking 130 MB, thats with 5 tabs open at the same time..

Firefox 3.5 is unusually bug-ridden but most memory problems can be attributed to the Flash plugin. So I believe everyone should start blaming Adobe and not Mozilla.

Flash can and will eat up huge amounts of memory and CPU. You can witness this in Chrome which runs the plugin in a separate process. In Chrome you can just kill this process and everything goes back to normal. In Firefox, for now, you have no other option but to restart the browser.

I know firefox has a memory problem but frankly at 1 gig I cared at 4 I dont. cpu stayed the same and it seems like the memory leak slows down at abt 500 megs. I do run alot of plugins and leave alot of windows open but thats what its there for.

I don't think it's related to Plugins. I have only WOT and ABP together with the Norton Toolbar. My firefox takes up 150MB of RAM and that's a lot considering I have only 1 GB of RAM.

Thanks for the information you gave me. From now on, If your going to run a resource hog, it would be best to first shut down your FF. Anyway, can anyone please inform the FF Devs about this?

hmmm this is interesting what you said about the flash plug-in, so far I don't use flash with minefield x64 since it's not compatabile, and have added most of my usuall add-ons and memory usage now is very small, usually below 100 Megs ( currently 80 Megs with 1 tab only ). they said you can't run add-ons well with minefield x64 but so far the only add-on that doesn't run for me is adobe flash.

Im intriqued as to how you managed to install 32-bit addons on a 64-bit browser as theyre not compatible.

I have very similar problem with Firefox.

I'm currently using Firefox 3.6 (nothing much different at first except last couple of week the problem starts). But the second problem is when ever I close the Firefox, the Windows freezes right after the closing. I'm using Windows 7 64-bits. Also most of the time it occurs when the bar on top (the the name of application name is) suddenly turns to light blue color. Everything is working fine, as soon I close it, it freezes the Windows
