It's a little clearer now. I remember when I used it on Fedora, I noticed that it was indeed a little slower than its Debian counterpart, but I never noticed any RAM usage. At this point, I think it's a problem with the Fedora version because on Debian the browser browses well and quickly, so I don't think there are any issues with excessive RAM usage. In any case, as soon as I start it, I'll let you know how much it uses while browsing.
