Question

I am developing a small extension that has to redirect certain URLs to another Site. It’s working fine, except for one situation: if open the Link with ‘Context-Menu -> Open in new Tab’, the current page is redirectet to my page and a second tab opens with the link that should be redirected. What am I making wrong? Is there a better way to achieve what I want?

var myListener = {     QueryInterface: function(iid)      {          if (iid.equals(Components.interfaces.nsIURIContentListener) ||           iid.equals(Components.interfaces.nsISupportsWeakReference) ||              iid.equals(Components.interfaces.nsISupports))              return this;          throw Components.results.NS_NOINTERFACE;      },      onStartURIOpen: function(aUri)      {             if (check_url(aUri)) {                 getBrowser().mCurrentTab.linkedBrowser.loadURI(######REDIRECT IS HERE#############);                 return true;             }             return false;      },      doContent: function(aContentType, aIsContentPreferred, aRequest, aContentHandler )      {            throw Components.results.NS_ERROR_NOT_IMPLEMENTED;      },      canHandleContent: function(aContentType, aIsContentPreferred, aDesiredContentType)     {            throw Components.results.NS_ERROR_NOT_IMPLEMENTED;      },      isPreferred: function(aContentType, aDesiredContentType)     {          try         {              var webNavInfo =              Components.classes['@mozilla.org/webnavigation-info;1']                          .getService(Components.interfaces.nsIWebNavigationInfo);              return webNavInfo.isTypeSupported(aContentType, null);          }        catch (e)        {              return false;          }      },        GetWeakReference : function()     {         throw Components.results.NS_ERROR_NOT_IMPLEMENTED;      } }

Okay, I did some research. The Hook was a wrong aproach. I changed the code now. Look into the git to find out more…
