Chrome扩展程序可在所有网站上使用，并仅对少数几个网站执行不同的操作

我正在尝试扩展以在所有网站上都可以使用。对于某些网站特定的网站（Google和LinkedIn），我希望执行其他一些操作。我已经设法在Googlegoogle.com/search搜索页面linkedin.com/vsearch/和LinkedIn搜索页面上对其进行了处理，并分别执行了操作A和B。但是我正在努力使其在所有其他站点上都能执行操作C。

但是在这里，谷歌和搜索中链接的前两种情况工作得很好，我只在预期的那些页面上得到了回调（动作A和B）。我也能够在其他站点上调用动作c。但是actin c是我也一直在不需要的每个新标签页操作上调用google和linkedIn搜索页面。我该如何解决呢？任何想法？
