Than why does it make such an impact on my PC? I just said it works wonders.... On version 13 at least, maybe not on 4 because of compatability issues?If the RAM usage annoys you so much, there are add-ons out there that really improve the RAM usage. I've got one (Memory Fox), that you can enable by clicking the button and it REALLY does a lot of 'damage'. I've seen it reduce my 700MB process too 200MB or even less.
I must say the browser doesn't work as smooth then, but that's only logic.
I only use it at times when I really need my 4GB RAM, but it does it's job wonderfully.
memoryfox don't do shit, i uninstalled that crap a long time ago, also i must be in the majority then because my version of firefox is still on version 4.0 i haven't upgraded since then and i doubt that will change, when i get a new pc i don't think i will be reinstalling firefox on it, will be using chrome instead.
