The way they do it in Chrome/Chromium is preferred. Unless you have an absolute need for some IEism I'd say just use Chromium. Even the nightly build zips are pretty stable. You can look in the xml file to see if there's a bunch of issues or tests with that build. Or just wait until one is noted on Softpedia. Those tend to be very stable.
Also the main bug I've noticed in Chromium that pops up now and then is losing the favicons. That's pretty minor. To me the Chromium nightlies for Windows are more stable than most beta releases I've tried with other browsers.
It helps if you have some memory/horsepower since coming up to a blank page is uses like 8 processes. But it snaps open, unlike FF.
I can't see going back.
For privacy concerns if you uncheck all the options under the Privacy setting then at least in Chromium it shouldn't track you.
I wrote a little script just to visit all the pages in my bookmarks file to restore favicons as that seems to be the most popular bug if you get a bug.
Oh, almost forgot the main point. With Chrome/Chromium you can set up aliases for search engines. Say google is your default, just typing keywords in the address bar searches google. But if I want to search d-addicts for the titles of Asian TV Dramas, I just prefix the search with alias "da" in the address bar. I have "av" to use AltaVista and so on. Very flexible.
