Hang opening the History menu or the History sidebar

Firefox may hang when using the History menu or sidebar if your browsing history has grown too large. To fix this issue, clear the browsing history:

Hang loading websites

Automatic proxy configuration file

If you're using an automatic proxy configuration file (PAC), Firefox may hang when you attempt to load sites that don't exist or that you haven't opened recently. To determine if you use an automatic proxy configuration file:

1. 在屏幕顶部的菜单栏里点击 Firefox 并选择 设置（在旧版 macOS 上选择 首选项）。点击菜单按钮 并选择 设置。
2. Click the Advanced icon.
3. Click the Network tab.
4. Click Settings. The Connection Settings dialog appears.
5. If Automatic proxy configuration URL is selected, you are using an automatic proxy configuration file. Do not disable this setting, which will prevent you from accessing the Internet. Instead, provide this link to your network administrator.
6. Click Cancel.

Duplicate Session Restore files

Firefox may be be slow to respond or hang if multiple copies of its Session Restore file have been created:

1. 要打开你的用户档案文件夹：

   • 点击菜单按钮 ，再点击 帮助 并选择 更多故障排除信息。从 帮助 菜单中， 选择 更多故障排除信息。然后，故障调试信息 标签页会出现。
   • 在 应用程序概要 部分的 配置文件夹配置目录旁边，点击 打开文件夹在 Finder 中显示打开目录 按钮。含有配置文件夹的窗口将打开。配置文件夹将打开。
   注意：如果点击 打开文件夹 时，Firefox 显示错误或者如果您无法打开或使用 Firefox，您也可尝试 在不打开 Firefox 的情况下找到您的用户配置文件 中的指导。

2. 点击 Firefox 菜单按钮 ，然后选择 退出。

   在屏幕顶部点击 Firefox 菜单，然后选择 退出 Firefox。

   点击 Firefox 菜单 ，然后选择 退出。

3. Locate and delete the sessionstore.js file and any copies, such as sessionstore-1.js, sessionstore-2.js.

Plugins

Sites that use plugins such as Java, Adobe Reader, or Flash can cause Firefox to hang. For information on troubleshooting plugins and on determining whether a plugin is causing your problem, see the 解决插件引起的故障 article.

Hang after prolonged use

Firefox may hang if left open for long periods of time. To fix the issue, restart Firefox.

If you regularly leave Firefox open so that you return to where you left off, you may want to use Firefox's Session Restore feature. When you exit the program, Firefox can remember your open windows and tabs. When you restart Firefox, you can optionally reload those windows and tabs.

To enable Session Restore:

1. 在屏幕顶部的菜单栏里点击 Firefox 并选择 设置（在旧版 macOS 上选择 首选项）。点击菜单按钮 并选择 设置。
2. Click the General panel (Main panel in Firefox 3.5).
3. From the When Firefox starts drop-down, select Show my windows and tabs from last time.
4. 关闭 设置 页。您做的所有更改都会自动保存。

Firefox is now configured to remember your windows and tabs. You can close Firefox without losing the currently opened web pages, which may prevent Firefox from hanging.

Hang deleting bookmarks folder

Trying to delete a bookmarks folder that contains many bookmarks and multiple levels of sub-folders can cause Firefox to hang. To work around this problem, delete unwanted bookmark sub-folders in small steps. .

Hang at exit

Sometimes when you close Firefox, it may stop responding and remain in memory, even though no Firefox windows are open. This can prevent Firefox from working properly the next time you open it or you may see a "Close Firefox" dialog box with the message, Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.. You must then end all Firefox processes or restart the computer before you can reopen Firefox. (See Firefox 已经在运行，但是没有响应 for other causes and solutions.)

If Firefox processes that remain in memory at exit are a recurring problem, try these solutions:

• A problematic extension can cause the problem, which can be resolved by disabling or uninstalling the extension. For information on diagnosing and fixing problems caused by faulty extensions, see the Firefox 扩展和主题的故障解决方法 article.

• Sometimes Java applets can cause the Firefox process to persist after exit. Try updating Java to the latest version or, if you don't need the Java plugin, you can disable it from the Plugins panel of the Firefox Add-ons window. For more information, see Firefox 中使用 Java 插件.
