> This is blocking the sort of extensions that get installed with other desktop software. So, like, for whatever god damn reason Microsoft thinks it needs to install Office addons into Firefox when I install Office. That wouldn't fly in Chrome now. As someone else commented below, Firefox has blocked this for a while now. So this will no longer fly in any major desktop browser (except perhaps IE, but in your example it's made by the same company installing the addon ;)
