Firefox will only obey requests to raise a window if a security option is set, and it's not set by default. Chrome won't pay attention to focus() requests at all, as far as I can tell. Safari does obey focus() request.
如果设置了安全选项，Firefox 只会服从引发窗口的请求，并且默认情况下未设置。据我所知，Chrome 根本不会关注 focus() 请求。Safari 确实遵守 focus() 请求。
The specific Firefox setting is in the "Tools" -> "Options" ("Edit -> Preferences" on Linux, maybe MacOS) dialog. There's a "Content" tab, and in that there's a checkbox for enabling Javascript. Along with thatis an "Advanced" button that brings up anotherdialog, wherein one finds a checkbox to allow (or disallow) the raising and lowering of windows by page code.
特定的 Firefox 设置位于“工具”->“选项”（Linux 上的“编辑 -> 首选项”，也可能是 MacOS）对话框中。有一个“内容”选项卡，其中有一个用于启用 Javascript 的复选框。随着该是一个“高级”按钮，带来了另一个对话框，其中一个发现一个复选框，以允许（或不允许）的升高和通过页代码降低窗口。
edit:Here is a test page: http://gutfullofbeer.net/focus1.htmland you should be able to see that Firefox willraise a window when the page calls window.focus(). You must either have the browser set up so that new windows (created with window.open()) open up in a new separate window instead of a tab, or else you can tear off the tab of the secondary page when it opens.
编辑：这是一个测试页面：http: //gutfullofbeer.net/focus1.html，您应该能够看到 Firefox在页面调用时会弹出一个窗口window.focus()。您必须设置浏览器，以便window.open()在新的单独窗口而不是选项卡中打开新窗口（使用 来创建），否则您可以在辅助页面打开时撕下该选项卡。

I had the same problem, i though there was a problem with my JS script, after a long search i have found a solution:
我遇到了同样的问题，虽然我的 JS 脚本有问题，但经过长时间的搜索，我找到了解决方案：
1) In a new tab, type about:configin the address bar and press button "Enter". Click the button "I accept the risk!" in order to confirm the warning
1) 在新选项卡中，在地址栏中键入about:config并按“Enter”按钮。点击按钮“我接受风险！” 为了确认警告
2) In the search field, type dom.disableto get dom.disable_window_flip
2) 在搜索栏中，输入dom.disable得到dom.disable_window_flip
3) If the property dom.disable_window_flipis true, double-click it to switch the value from true to false
3）如果属性dom.disable_window_flip为true，双击它，将值由true切换为false
