Rated 5 out of 5 stars

I spend most of my life on my computer. I'm a history buff and also technically inclined, and as a result I have a constant need to look up things. WikiLook has made that process instantaneous, and my online knowledge hunting easier than ever before. It's quite simply the most useful add-on I know of. If you're a knowledge junkie like me then this is a must-have tool.

This review is for a previous version of the add-on (2.5.5).
