LivemarksLiberated

From Chickenfoot Script Repository

Originally, I was going to make LivemarksLiberated a full-fledged Firefox extension, but then I realized that it would be much quicker to release it as a Chickenfoot script. As Chickenfoot has only been verified to work up until Firefox 1.0.7, I'm not sure if this script will work with Firefox 1.5. Specifically, the code to attach the listener to the Live Bookmarks button may no longer be valid, as the XUL for Firefox tends to change from version to version.

To install this script in Chickenfoot, add the code below to an empty Chickenfoot editor, then hit the + button in the Triggers pane to add this script as a trigger. You can give the trigger any name you want (LivemarksLiberated is preferred), but make sure the value of the For Pages textbox is *.

(The details about how this script was created (http://www.bolinfest.com/changeblog/2005/12/05/livemarksliberated-the-first-chickenfoot-script-to-hit-the-repository/) are on my blog.)

/**
 * LivemarksLiberated overrides the orange Live Bookmarks button,
 * giving the user other options for what to do when adding a feed.
 * Set your option by assigning a value to the variable "myMode", 
 * defined below.
 *
 * Here are the possible values for myMode:
 *
 * DEFAULT - do what Firefox normally does, add it to your live bookmarks
 * CLIPBOARD - add the URL of the feed to the clipboard
 * GOOGLE_READER - add the feed to Google Reader
 * GOOGLE_HOMEPAGE - add the feed to your Google Personalized home page
 * PROMPT - ask the user to select one of the above options when a feed is selected
