Well Hal, I agree partially. I am not a Firefox user. I used it for a while. I also tried Opera. I didn't really like either. I settled with My IE 2 and I love it. It has built in pop-up blocking, mouse gestures, and, yes, tabbed browsing. I like the tabbed browsing in MIE2 because to switch pages all I have to do is either move the mouse to the tab bar and use the scroll wheel or hold the right mouse button and use the scroll wheel. I find it much more convienient than clicking on things in the taskbar. I also like the undo button because I always do things that I didn't want to do. All browsers should have an undo button.
I also have it set so that when I hit the web/home button on my keyboard MIE2 opens both my Hotmail inbox and PCmech at the same time. I just love this browser. As for speed, it is instant on all pages. It has never slowed down. I do clear the cache once in a while which probably helps. That's another thing. MIE2 puts all those options (clear search bar history, cache, cookies, addresses, form data, etc.) right in the tools menu. The simple collector is another usefull thing. It is sort of like a small notepad with different tabs. I have links I use often, system specs, and other things in the simple collector for quick copy/paste access.
