抱歉，没有跨浏览器的方式来做到这一点.您的 FF 示例也已损坏:它不会创建常规书签，而是设置要在侧边栏中打开的书签.你必须使用书签服务来创建一个实际的书签，但这'会因安全限制而失败.

Sorry, but there's no cross-browser way to do this. Your FF example is broken as well: It won't create a regular bookmark, but a bookmark set to be opened in the sidebar. You'd have to use the bookmark-service to create an actual bookmark, but this'll fail due to security restrictions.
