Why by default Firefox uses so much RAM?

delavaca

I tried to use Firefox in three different computers but only in the one with over 4 GB of ram is usable. Why it uses so much RAM and renders so slow? Specially the scroll is really laggy.

I tried clean installations but they do not fix the issue.

When opening Firefox and Chrome and playing a video in YouTube, Firefox uses over 500 MB while Chrome uses less than 300 MB. Both with the same single addon.

Is there something that can be done to use Firefox in computers with less than 4 gb of RAM?

Yes, how is it possible that a single tab eats as much as 4GB ram (and counting) ?? What's in there ? 4GB !!! Garbage collector on strike ? ;-)
