Out-of-process plugins landing soon in Firefox as a minor update (3.6.4)

If I understand correctly what is being done with Firefox, it will emulate Chrome as treating each tab as a process, so that when one tab crashes, that process is terminated, leaving the other tabs intact. That's called crash-proof ?

In that case, Firefox will then eats up a lot of RAM and CPU usage

 

Already Firefox is eating memory, and i wonder how this change will affect.
In Chrome when installed multiple extensions is draining all the memory.

 

I think Mozilla is doing the right thing by going the separate process route for safety reasons. However, one big glaring issue, imho, has been that, while indeed safer, this method chews up memory and CPU usage like a fat kid with a pocketful of candy. It's one of the reasons I dropped Chrome. Yes, I have 6Gb of RAM, yes, I have a decent dual-core processor. But no, I don't want one application trying to hog it up.

Firefox already has a penchant for being a memory addict, I'm almost nervous to see what will happen when Mozilla begins this.
