Firefox uses less memory only on startup and when I have few tabs open. As soon as I start opening more tabs and browsing longer the memory usage is much larger on FF and the whole UI becomes less responsive and so do pages.

Even on startup it isn't that better compared to chrome.

Chrome 11 extensions 1 tab: ~300MB

FF 2 extensions 1 tab: ~200MB

It's not FF 29, it's 28 - but I doubt the memory management improved much in 29.

But to be fair, it's a lot better now than it used to be.

That surprises me even more, since Chrome has a lot more overhead per tab (often a whole process per tab), so I expected Firefox to have a bigger advantage the more tabs you have open. Edit: I just tried opening about 24 tabs of webcomics in each, and Chrome jumped to over 1GB of RAM while FF is about 600MB.

I don't know if it's just the tab count or longer browsing sessions/history (I usually have my browser open for days without closing it) or whatever, so don't quote me on that.

But FF is definitely uses more memory than chrome and with few other resource hungry applications running it becomes practically unusable on my low end laptop.
