Oh well. Mozilla Suite 1.8a6 is way fast. Whee! It also doesn't have an obnoxious bug from Mozilla 1.7.5 where I could middle click links in mail to open them up as tabs. Which makes me really, really happy. Of course, it doesn't really tell me when I have new mail, which may or may not be a theme thing.
I'm also messing about with Portable Firefox, which is pretty damn nifty.
