I recently added an experimental addon called Ubiquity to my Firefox addon arsenal.
This addon allows the user to collect content form all over the web and then stitch them together so that they can, suppose, email the new contents to a friend. Also, it comes with many features that will make life easier on the web.
Here is how Ubiquity looks:
Notice that black frame on the right side of the window under the tab bar. It is the Ubiquity console. You can enter commands like google, map, weather, define etc. Here is the image command which searches for images related to a keyword on Flicker.
Clicking on the image will take you to the related Flicker page.
The most interesting feature of Ubiquity is it ability to send images, maps etc using Gmail email service. For example you found an image on xkcd that you think a friend of yours must look at. Then you can simply select the image and type the command:
email this to <your friend’s email address>
As soon as you hit enter, you will be presented with your Gmail inbox (if you are already logged in) with the To: address set to <your friend’s email address> and the body containing the picture you selected at xkcd.
There was another command, map, which looked very useful in the demo. But the command did not work (geoip_latitude not defined error).
Ubiquity has got a lot to empower you with variety of resources from all around the web. Try it yourself and find out what more it has got. Also considering sharing your finding.
