> Even I noticed that Chrome uses more RAM that FF

Reflects my experience. I use Firefox at work, Chrome at home. Chrome RAM usage is much higher than FF. Not that I really mind - I have more than enough RAM to support it. But it often leaves me wondering if some tab/plugin/extension is misbehaving, which in turn forces me to close all my tabs only to find that the memory use stays high and the number of Chrome processes doesn't decrease as expected. I'm considering switching back to Firefox at home now.

EDIT: OK, tested with Firefox now. Number of process doesn't decrease as I close tabs either, but memory use is still considerably higher than Chrome.



In Firefox, entering about:performance in the URL bar will give you some statistics on how much memory or CPU each tab is using.

Entering about:about in the URL bar gives you a short list of interesting about:* links that you can play around.


I just saw that I'm using more RAM that I thought, but Tab suspender really works fine to keep ram usage at bay.


Firefox uses a process model that has a higher base memory usage than Chrome's but overall lower memory usage when used with a lot of tabs.
