This is a very useful add-on! The only trouble was that link widgets would interfere with shortcuts like "Command-," for opening preferences. Fortunately, the Link Widget keyboard shortcuts can be disabled with the keyconfig extension: http://mozilla.dorando.at/

BTW, I am using Link Widgets on FF4 thanks to the Add-on Compatibility Reporter extension which will override the add-on compatibility checking. It works like a charm: https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/

This review is for a previous version of the add-on (1.6.6).
