Once again, I come late to this particular party, but the recommendations +Guy Kawasaki makes are too good not to share. (This is an hour long video which is why it took me a while to find some time to watch through it.)
tl;dr version: (or should that be tl;dw? Anyway…) There are three Chrome extensions Guy recommends in this video & he shows why he uses them.
They are listed below, and I agree they are very useful and time-saving!

+Jean Egan Are you part of Guy's #evang+ ? I still have yet to read his ebook on Google+. Adding this video to the must-watch list, thanks for posting.
There is one more thing that makes watching the video very valuable – it's his comparison of how his business model is similar to NPR.
I won't take the time to type why I think it's a great business model, but have to say it's thoughtful to think of your business this way – and it makes me feel less guilty to not share as much "targeted business stuff". This model is a natural for me – and absolutely removes the guilt I was feeling for not hawking my business as much. Ask when it's absolutely necessary and otherwise be helpful and share valuable content. Woo hoo!
I like that philosophy…will make watching this a priority.
Hello Eunice! Yes – I am also a part of his #evang + - I should have posted that tag in my post – oops! Hehe! I'll fix that.
I also have yet to read his book but in time I will be, I'm sure.
(Thanks for checking this post out!)
+Jean Egan To add to your comment on extensions he shares, he also gives out a couple of content sources that are new to me:
http://alltop.com/ and http://www.futurity.org/ .
Thanks +Jean Egan very good.
Thanks for sharing, Eunice!
Glad to share, Lindy. Hope it's as interesting to you as it was to me!
Yes it was. I don't actually follow Guy K for a long time now but this was useful. And I have only recently started using Chrome so handy to learn about the apps. Thanks +Jean Egan ;-)
