Also, the item_1@domain Extension Manager item will be blocklisted if a version between <tt>3.0</tt> and <tt>3.0.*</tt> (e.g. less than <tt>3.1</tt>) is installed and the Firefox (e.g. <tt>id</tt> equal to <tt>{ec8030f7-c20a-464f-9b0e-13a3a9e97384}</tt>) version is between <tt>1.5</tt> and <tt>1.5.*</tt> (e.g. less than <tt>1.6</tt>) or the Toolkit version is between <tt>1.8</tt> and <tt>1.8.*</tt> (e.g. less than <tt>1.9</tt>).
