Quick fix for version 1.7.0.1 Rated 4 out of 5 stars

This great add-on version 1.7.0.1 stopped working in my Firefox 22.It worked again by simply commenting out lines 376 to 386 of %APPDATA%\Mozilla\Firefox\Profiles\[...].default\extensions\linkwidget@clav.mozdev.org\chrome\content\code.js

TypeError: Value does not implement interface XULCommandEvent.
Source file: chrome://browser/content/utilityOverlay.js

Patch for code.js:

loadPage : function(e) {
const url = e.target.linkURL;
/* deleted */
LinkWidgetCore.loadPageInCurrentBrowser(url);
},
