The idea of having a Firefox extension that gives you content related to what you are looking at is nothing new really, however I have found a Firefox add-on that will help you get it done in a new and exciting way.
Headup underlines words on pages when you browser. When you hover over those words, you get relevant content from popular web services.
Technically speaking, they “presents you with textual and rich media content related to the objects and terms it identifies on the pages you browse.” Here are a few more examples from their web site:
Use Headup’s ability to recognize objects and relationships to discover all kinds of information quickly and effortlessly. Here are some examples:
- Discover which of your friends like a particular band and gain access to the band’s videos and lyrics.
- Find blog posts and stock news about a company and discover which of your contacts work there.
- Get alerted about your friends’ birthdays and see which books they’re likely to enjoy as a gift.
Overall, I have to say it is an interesting idea – and a cool tool. Sometimes these semantic plugins kind of confuse the general public, so I would really recommend playing with Headup to see if it is right for you. You can pickup the Headup add-on on Headup.com or the Mozilla Add-ons web site.
