One of the features I like about FF is that it gives you the option to remember user names and passwords. Not sure if the latest Chrome and IE do the same??
Google Chrome has a neat little feature where highlighting text spawns a popup, allowing you a quick launch to Google search, and Wikipedia relating to what you highlighted.

Anyone know how I can do this in Firefox?
