I've noticed that firefox seems to want to continually eat more & more memory, even if I close all tabs that I had open, leaving just two or three (earlier, I had about six tabs max open, now just two) open. Closing all that doesn't affect memory, though ...why does firefox eat more memory & not return it until it's completely closed?. I already apply tweaks which one digit member mentioned under tutorial section. I am using latest firefox 3.0+ with windows xp prof sp2.

current updated version of firefox is 3.0.11 . If it still eats up memory in the updated version I will call it memory leakage.

How much RAM do u have? If 1GB or more, then WHY THE HECK are you complaining?

And without add-ons and 5 tabs, mine on XP SP3 does it at 86MB sweet. I hardly call that moads of memory usage considering it's stellar performance and c'mon, it's FIREFOX!

Try disabling add-ons btw if u need a light-weight browser then Chrome will be ur best bet

Recent Firefox versions have become a bit heavy! And the more add-on's you have the memory it would eat up. Try using only the add-on's you need and uninstall the one's you don't.

+1 Surfing with FF s truly Enjoyable with lot of Addons, themes and so about...
But think of PCs wth low configs - Using 88 MB's of Memory for a browser is crime *gigasmilies.googlepages.com/39.gif

I too have a similar issue. 3 tabs open and 142MB.
But if I start a new session the usage reduces.
I think it has something to do with the feature which loads many things into RAM to make fetching faster. Because page load times are quite good here.
