Firefox挂起

Firefox挂起的问题

当一个程序被 '''挂起''',它不再接受用户输入，也似乎不再执行任何操作。挂起的其它术语有“冻结”或“未响应”。 *挂起程序不同于已崩溃程序；崩溃[[Firefox crashes|crash]] 使程序结束。 *挂起程序不响应你的操作。在其它情况下， Firefox回应您对菜单和按键的操作，不加载任何网站。 该文章未明确提出如何解决挂起程序，或者建议的解决方案并未解决问题，请见“基本故障排除 ”。你还应该扫描电脑看是否是病毒、间谍软件和其它恶意软件，并阅读“我的问题是恶意软件造成的吗？” 挂起加载第一个窗口 加载第一个浏览器窗口时，可能由于“超线程”而被挂起。对一些英特尔奔腾4处理器的功能，“超线程”旨在提高性能，但它也会导致Firefox挂起。 如果您的计算机有英特尔奔腾4处理器和使用Windows 2000和XP系统，您可以禁用“超线程”。 1.右键单击用于启动Firefox的快捷图标。 2.选择属性。 3.选择兼容性图标。 4.选择以兼容模式运行该程序。 5.在兼容模式的下拉菜单中选择Windows98/Windows Me。 6.点击确定。 7.重启Firefox，看挂起是否已经消失。 挂起加载每一个窗口 SwitchProxy工具延期检查更新每次打开新窗口的时间。这是一个已知的问题。 如果您使用SwitchProxy工具，您可以禁用它来看挂起是否被阻止： 1.点击Firefox窗口顶部菜单工具栏的“工具”，然后选择附加组件。出现附加组件对话框。 2.选择扩展面板,将会看到已安装的扩展名列表。 3.选择SwitchProxy工具。 4.单击禁用。 5.在Firefox窗口顶部菜单栏中选择文件，然后选择退出。 6.重启Firefox。打开几个新窗口，看Firefox是否不再被挂起。 挂起下载文件或保存图像 当您想下载文件或保存图像时Firefox被挂起，请尝试以下解决方案： 清除下载历史记录 如果您下载历史记录太大，下载文件时Firefox可能被挂起。清除下载历史记录： 1.点击Firefox窗口顶部菜单工具栏的“工具”，然后选择下载。下载窗口被打开。 2.点击清除列表。下载历史记录被清除。 3.下载一些示例文档，看挂起是否挂停止。 选择不同下载文件夹 如果最后一个下载文件夹位置（如：共享卷标或USB驱动器）不再可用，Firefox可能挂起。为解决此问题： 1.点击Firefox窗口顶部菜单工具栏的“工具”，选择选项。 2.选择常规（主控制屏在Firefox 3.5）。 3.在下载窗格中，选择保存到文件，然后单击浏览按钮。 4.在浏览文件夹窗口，选择一个新文件夹位置。 5.单击确定来关闭选项窗口。 查看您现在是否可以下载文件或保存图像。如果可以，您可以回到Firefox设置，如果您愿意，请选择“总询问保存文件的位置”。 = 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: {for fx3} # {for win,linux}At the top of the Firefox window{/for}{for mac}On the menu bar{/for}, click the {menu Tools} menu and then select {menu Clear Private Data...}. The Clear Private Data dialog appears. # Deselect all boxes except '''Browsing History'''. # Click {button Clear Private Data Now}. The browsing history is cleared. See [[Clearing private data]] for more information. To prevent a recurrence of this issue, you can configure Firefox to retain a smaller browsing history, in the [[Options window - Privacy panel]]: # [[T:optionspreferences]] # Select the {menu Privacy} panel. # In the '''Keep my history for at least XX days''' text box, enter a value that is less than the current one. This value defines the number of days that Firefox retains browsing history; a lower figure should result in less retained browsing history. # [[T:closeOptionsPreferences]] {/for} {for fx35} # {for win,linux}At the top of the Firefox window{/for}{for mac}On the menu bar{/for}, click on the {menu Tools} menu, and select {menu Clear Recent History...}. # In the '''Time range to clear''' drop-down menu, select {menu Everything}. # Click the button next to '''Details'''. A list of history items will be displayed. # Select '''Browsing & Download History'''. # Click the {button Clear Now} button. The Clear Recent History window will close and your browsing history will be cleared, as well as the Download history. See [[Clear Recent History]] for more information. To prevent a recurrence of this issue, you can configure Firefox to retain a smaller browsing history, in the [[Options window - Privacy panel]]: # [[T:optionspreferences]] # Select the {menu Privacy} panel. # Beside '''Firefox will:''', make sure {menu Use custom settings for history} is selected, if it isn't already set. # In the '''Remember my browsing history for at least XX days''' text box, enter a value that is less than the current one. This value defines the number of days that Firefox retains browsing history; a lower figure should result in less retained browsing history. # [[T:closeOptionsPreferences]] {/for} = 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: # [[T:optionspreferences]] # Click the {menu Advanced} icon. # Click the {menu Network} tab. # Click {button Settings}. The Connection Settings dialog appears. # 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 [https://bugzilla.mozilla.org/show_bug.cgi?id=235853 this link] to your network administrator. # Click {button 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: # [[T:profileFolder]] # [[T:closeFirefox]] # Locate and delete the {filepath sessionstore.js} file and any copies, such as {filepath sessionstore-1.js}, {filepath 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 [[Troubleshooting plugins]] article. {for win} = Hang switching tabs = Spybot S&D's "Immunize" feature can add a large number of entries into the Firefox cookie configuration file. This can cause slowdown while switching tabs. # From the menu at the top of the Firefox window, select {menu File} and then select the {menu Exit} menu item. # Open Spybot S&D. # Click the Immunize icon on the left side of the window. # Right-click in the Immunization list and choose '''Deselect all''' from the context menu. # In the '''Firefox''' section, put a check mark next to each item. # Click {button Undo} at the top of the window. {/for} = 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: # [[T:optionspreferences]] # Click the {menu General} panel ({menu Main} panel in Firefox 3.5). # From the When Firefox starts drop-down, select '''Show my windows and tabs from last time'''. # [[T:closeOptionsPreferences]] 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. <!-- Also applies to Firefox 3.5 - see https://bugzilla.mozilla.org/show_bug.cgi?id=432706 (reopened bug) -->. = 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 is already running but is not responding]] 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 [[Troubleshooting extensions and themes]] 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 [[Using the Java plugin with Firefox]]. {for win} *Using certain Internet security software is reported to cause the issue on some systems: **If you use ZoneAlarm on Windows Vista, uninstall it and use another firewall product (or use the Windows Firewall). **If you use Avast! Antivirus, switch to another antivirus product if you also have ZoneAlarm installed. **If you use Norton 360 2.0, make sure that you have all available Norton updates (for more help, contact [http://www.symantec.com/norton/support/index.jsp Norton Support]) and that you have followed the instructions in the [[Configuring Norton 360]] article. <!-- http://support.mozilla.com/tiki-view_forum_thread.php?comments_parentId=155142&forumId=3 --> **If you have upgraded Comodo Internet Security from a version prior to 3.10, the Comodo Safe Surf component from the previous version can cause Firefox to hang at exit. To resolve the issue, you can uninstall Comodo Safe Surf via Windows Control Panel, as its function is now integrated into the current Comodo application. <!-- http://support.mozilla.com/tiki-view_forum_thread.php?forumId=1&comments_parentId=384477 and http://support.mozilla.com/tiki-view_forum_thread.php?forumId=1&comments_parentId=384318 (Other references in the MZ article) --> {/for} <!-- MZ credit --> <br/> <br/> '''''Based on information from [http://kb.mozillazine.org/Firefox_hangs Firefox hangs (mozillaZine KB)]'''''
