Comment 4 for bug 669926

I’d estimate the effort needed to more than one day.
This is roughly the list of tasks:
 1) Implement a command-line switch to unity-qt-launcher that allows passing in URLs to be favorited
 2) Implement URL and favicon fetching, and building a desktop file with the information retrieved
 3) Port the chromium extension from Omsk

Optionally, we should also port the extension for firefox, if such an extension already exists, and write it from scratch otherwise.
