I thought it was particularly appropriate, given how often we ask people to simply Google...
Google just released their toolbar, rev 2.0. Available here:
http://toolbar.google.com/
(Or go to
http://www.google.com , then select "Services & Tools").
It also acts as a pop up blocker.
And it's free!
Requires Windows 95 or higher, MS IE 5.0 (5.5 for the pop up blocker) or higher.
Tip: disable "PageRank" for privacy.
