There is Still No Good Browser

Is it just me, or do all browsers for PC still suck? I keep going from one to another and always end up frustrated and dissatisfied. I open up Firefox and am, for a little bit, happy with its great UI, etc etc. But after opening Meebo.com, Gmail, and another window for development, memory usage shoots through the roof, rendering the browser unusable. So I get frustrated and switch to IE7, which does not eat up so much memory, so, willing to settle with more than a few UI annoyances and security flaws, I happily crack open a few tabs and work away. But IE7 doesn’t like me, and regularly crashes several times a day. I briefly consider Opera, but I guess I now have to avoid the half of the web that doesn’t support it (including, for one, Google Docs). Sounds pretty lose-lose to me. Anyone want to fix Firefox’s memory leak problems pretty please?
