hi leonx123, please see the banner at the top of the support page - unfortunately there's a technical issue (failing addon signature verification) at the moment that's prohibiting the installation and in some case the usage of installed addons for firefox.
mozilla is working on a resolution, expect a fix soon. in the meantime you could temporarily try winding back your system clock by a day or so to get around the issue. sorry for the inconvenience...
