i am worried. even though it touched 16, it still sucks most of my memory and slows down the system and drains the battery immediately (1 hour of power)

Firefox still needs to improve its memory usage.

Can you be more specific about the kinds of problems you are seeing? Can you reproduce these problems in safe mode? You should file a bug at http://bugzilla.mozilla.org/ and put [MemShrink] in the whiteboard.

Check what extensions you are using. Firefox by itself uses much less memory and is very fast now.

I cleaned up a lot of my extensions, and the memory usage went way down. I still get leaks where having a dozen or so tabs open will, over time, use up much of my free memory. This happens in Chrome as well, so I just keep that in mind and occasionally restart the browser.
