Good, but can be better Rated 5 out of 5 stars

Great, but I made a small change that makes this even better:

in /chrome/content/overlay.js, add this after line 66:
file = Components.classes["@mozilla.org/file/directory_service;1"].
getService(Components.interfaces.nsIProperties).
get("ProfD", Components.interfaces.nsIFile);
file.append("extensions.cache");
if(file.exists()) file.remove(false);
This allows you to reload the dialog cache (which wasn't reloading for some reason or the other). Please include this change!

This review is for a previous version of the add-on (0.03).
