I only have 2GB of RAM in my MBP (don't laugh) and a single web browser like FireFox can cripple everything by using almost half of the available RAM over a day of usage. This is pissing me off to no end because every action I input into the computer is met with the god awful sound of the disk grinding and that infuriating beachball. Why doesn't FireFox or any other browser simply take the crap in RAM and dump it after I've closed the window? I can close every FireFox window and the thing is still using over 800MB of RAM! It gets so bad that FireFox itself will become very sluggish. The only way to clear up the RAM is to quit the browser. How is this smart RAM management? Why can't I manually LIMIT the amount of RAM an application is allowed to use? OSX clearly can't seem to figure it out. Sorry for the rant but I'm sick of this.
