@asdf re: Firefox
I don't know which OS you're on, but FF 18.104.22.168 on a G4 tower under OSX runs like a champ. I tried 3.x on my iBook, but 3.x was dog-slow, so I downgraded to 2, and all is well. The wife still has FF 3.x on her laptop; she complains that it's slow, and I've offered to reinstall FF 2, but she's one of those people who refuses to be taught anything -- so I just let her be, and be thankful that we aren't running Windows at this house, as I'd never get any designing done for all the time I'd be pissing away scraping viruses and trojans and spyware off of her system.
Just for the hell of it, though, just to see what all the fuss was about, I just now went over and downloaded a copy of Opera 10 for OSX. The little fucker wouldn't even _launch_ -- you double-click it, it does the little zoomout effect, and... nothing. So, I went back and downloaded the most recent rev of Opera 9. It ran OK, but right off the bat, Little Snitch flagged two attempts by Opera to phone home; I clicked "deny", after which Opera refused to load any pages. So, I quit and relaunched Opera, and told LS to "allow until quit", after which everything worked fine. It even imported my bookmarks. Cool.
It was shortly after that when I realized why I ditched Opera after less than five minutes the last time around -- absolutely no control over the appearance of advertising, whether as gifs or Flash. I went to the Drudge Report page -- which I read purely for cheap laffs, I assure you -- and immediately remembered why I use Firefox/Flashblock/Adblock/NoScript. Opera's total lack of any kind of media filtering means I was hit in the face with the Drudge Report in all its horrifying Flash- and wiggling-gif-infested glory. Now, with the benefit of experience, I can belatedly join the El Reg Chorus Of Guys Telling Opera's Honcho To Quit Whining, Because Your Browser Sucks.
So, long story short: I'm sticking with FF 2, and this old copy of Mozilla, for those really anal-retentive sites that won't load under Firefox.
