Rated 4 out of 5 stars
Seriously a good addon.
To make this 'very' good addon, the following features can be implemented
*It should use the gmail/google login when i open gmail(so i need not login again for gmarks separately)
*Sync the firefox bookmarks and google bookmarks(so that i get better results in awesome bar itself)
*able to change the shortcut key from home+home(and dont launch a separate window for the search - it shows a new window in the task bar)
*integrate it into ubiquity's search
