At Calvin’s recommendation I downloaded and tried out TabMixPlus (a Firefox extension) and it’s awesome. It allows me to configure the tab open behavior to the model that I want which means I’m not going to be opening IE7 as often.
The program has a wealth of options and allows you to control just about every aspect of the tab browsing experience. Thanks for the pointer!
PS: On an unrelated note, the new Google Analytics interface has added hourly intraday data back in, which rocks.
