Firefox 插件 plugin-container.exe 导致的 Win7 变慢问题
您的计算机上火狐浏览缓慢？如果是的话，它可能是由于插件plugin -container.exe，这是Firefox的新版本增加的防止浏览器崩溃插件。

其实这玩意有多大作用呢，我不知道，我只知道它把我的电脑卡住了，果断禁用掉。
要禁用或停止Firefox插件plugin-container.exe？按照这些简单的步骤：
•打开Firefox浏览器。
•在地址栏中输入about:config，然后按下回车键。
•将出现一个警告。忽略它，按下“我会小心，我答应！”按钮。
•在过滤字段框输入dom.ipc，会出现6条过滤后条目。
•忽略第一个和最后的，分别双击剩余四个条目，改变每个值从“真（true）”到“假（false）”。
•就是这样。看截图。

Firefox 3.6.6 make browsing slow on your computer? If yes, it may be due toplugin-container.exe, which was added in recent version of Firefox to prevent browser crash. New version of Firefox web browser loads certain plugins in a separate process (plugin-container.exe) to provide you uninterrupted browsing even when certain plugins stops working. But the problem is, plugin-container.exe may use a lot of memory and slow down your computer. You may experience the problem more often while viewing online flash videos. So, want to disable or stop plugin-container.exe in Firefox 3.6.6? Follow these simple steps:
Steps to stop plugin-container.exe process:

• Open Firefox web browser.
• Type about:config in the address bar and press Enter key.
• A warning will appear. Ignore it and press the "I’ll be careful, I promise!" button.
• In the Filter field type dom.ipc. Six preferences will appear for the filter dom.ipc.
• Ignore first and last preferences. Toggle (double-click) each of the four remaining preferences to change the value from "true" to "false".
• That’s it. Look the screenshot.

Explanation: The crash protection feature in Firefox 3.6 is enabled for certain plugins only. The four preferences that we modified here specifies four different out-of-process plugins. They are the theNPAPI test plugin,Adobe Flash,Apple QuickTime (Windows) andMicrosoft Silverlight (Windows). These plugins are specified in a separate dom.ipc.plugins.enabled. preference by default is set to true. We can disable them by changing their value to false. And thus plugin-container.exe will not run. By default the preference dom.ipc.plugins.enabled is already set to "false". So, no need to touch it. The dom.ipc.plugins.timeoutSecs is also not important here as other values are false.
