如何防止 Firefox 消耗我的 CPU？

尽管许多人抱怨笔记本电脑的电池寿命短，但我对发热的电池更恼火。

通常，避免这种情况的最佳方法是禁用浏览器上的 Flash、点击播放每个插件等。我还会留意任务管理器以发现使用过多 CPU 的进程。

Firefox 是导致我的笔记本电脑发热的罪魁祸首，它占用了 CPU 的 120%，使 CPU 从舒适的 45ºC 升至 80ºC 以上，并且一直保持这种状态。有什么方法可以避免这种情况吗？

有任何想法吗？

支持数据 我使用装有 Yosemite 的 Macbook Pro，但我的另一台装有 Mavericks 的 Macbook Pro 也遇到了同样的问题。

您是否尝试过在安全模式下禁用所有附加组件来使用 Firefox？目前，在我的计算机上，Firefox 正在使用0.2% 的 CPU 处理，但在 YouTube 上播放 Flash 视频时，它会上升到约 2%，所以你遇到的行为是不是正常。要以安全模式启动：https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode。
