Stability and speed please
All I care about is NOT seeing, "internet explorer has stopped working".
Give me a stable browser that can have at least 10 tabs open without one of them crashing, And then causing the page or tab to not be able to close, Usually requiring a complete browser shutdown and restart. Damn that was annoying in IE.
I like IE's easy layout, Firefox's functions and Chromes speed, Now merge them all into one browser. ;)
