<h3 id="Notes" name="Notes">备注</h3>

<p>在普通网页中,如果about:config中存在<code>general.oscpu.override项,则</code>该属性的值会返回about:config中<code>general.oscpu.override项的值.</code> 在特权代码中 (chrome上下文或者拥有"UniversalBrowserRead"特权的网页中),返回的还是真实的操作系统类型.(译者注:语句:netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead ")用来激活所在网页的UniversalBrowserRead特权.)</p>
