My own habits are apparently just those, habits. I'm so used to using multiple browsers that I just keep firing up new browser sessions, even if it means finding the little "e" Icon to click on to do it.
I'm running IE7, and it is fully capable of tabbed browsing. Heck, I have Firefox installed on my box and use it rarely to access some sites that were problematic for IE7. In either though I tend to just start up a new browser rather than use tabs.
Every now and again I start up a new tab, and every now and then something I'll do starts up a new tab automatically, but given my preference I'd just as soon have a new window open.
I ask the question above because I'm curious just how accepted this great new feature is. Firefox users sneered at Microsoft a bit for adding something that was so prevalent in their own favorite browser, but how many people really use the feature anyway? Is it really something so important that you have to have it and can't live without that feature, or is it more like a neat trick to use every now and then?
