求助：插件无法卸载！

想卸载一下插件，在点击卸载后提示重新启动Firefox完成卸载，但是重新启动后还是没有卸载？请问插件都在安装在什么位置，能否一次全部卸载（再重新选择安装一些真正需要的）？

扩展位置
C:\Documents and Settings\用户名\Application Data\Mozilla\Firefox\Profiles\huktwibl.default\extensions

谢谢viewtheard，搞定了！！！

我也碰到这个问题, 但是光在那删没用, 程序目录里还有一个extensions目录, 可是删了以后全部插件都变成了将要安装, 只好卸载firefox重装，但是问题依旧最后装回firefox1.0才解决。我开始是1.0.1版。

我的问题和楼主一样，但想知道怎么看firefox的版本？

Manually uninstalling a plugin

If you can't use an uninstaller program to remove a plugin, you can remove it manually:

   1. In the Location bar, type about:config and press EnterReturn.
          * The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!, to continue to the about:config page.
   2. Search for the preference: plugin.expose_full_path.
   3. Double-click on the plugin.expose_full_path preference in the list to change the value to true.
   4. Enter about:plugins into the Location bar to display the About Plugins page.
   5. Each entry in the About Plugins page will have "File name:" followed by a path. Use Windows Explorer to navigateNavigate to the folder shown for the plugin you want to remove.
   6. Rename the file to something other than its normal name - e.g. npswf32 becomes Xnpswf32

The plugin will be removed.

用了这个方法还是不能卸载。

#  If the uninstall button and menu item are disabled, the add-on is locked. To uninstall a locked add-on, you'll first have to unlock it via Safe Mode.

Uninstalling manually

If you are unable to uninstall an extension, even after restarting your Mozilla application in Safe Mode:

Exit your Mozilla application, go to your profile folder and open the "extensions" directory. Each directory there is an extension. Remove the directory that corresponds to the extension you want to uninstall. (To uninstall ALL extensions, remove the entire "extensions" directory)

If an add-on directory there does not have a meaningful name, look inside it for its "install.rdf" file. Open that file in a text editor (such as Notepad) to see which extension the directory contains. Alternatively, in the parent folder, "extensions.rdf" contains a list of extensions, their names and corresponding GUIDs.

firefox中了一个叫作SkySearch Toolbar的恶意插件，“卸载”按钮被屏蔽（就是灰掉了），启动安全模式并屏蔽所有插件和工具栏也没用，profile/exetension和firefox目录下的exetension找了一圈，都删掉了也没用，本来绝望了，但是看到官方指南里的Global extension一条，说全局插件也可以用过注册表安装在firefox文件夹之外，一惊，到
HKEY_CURRENT_USER\Software\Mozilla\Firefox\Extensions\
HKEY_LOCAL_MACHINE\Software\Mozilla\Firefox\Extensions\
两个项下一看，果然有一个Skysearch toolbar，而且插件目录也在主键的值里面，马上到目录删掉，大功告成

挖坟自重。
