郭爽2007-02-18+其实你可以直接使用 firefoxPortable 或者 operaUSB，完美的解决方案！

1、自定义安装firefox在非系统分区，譬如E:Mozilla Firefox。然后在Mozilla Firefox文件夹中建立一个profile名字的文件夹。

2、先开始－运行：”E:Mozilla Firefoxfirefox.exe” -p，修改配置文件夹。并且在Mozilla Firefox文件夹中建立一个firefox.exe的快捷方式,修改其属性为：

“E:Mozilla Firefoxfirefox.exe” -profile “profile”

3、启动本快捷方式，安装插件，配置文件等做完一切！就可以了！你的一切配置文件插件全部在profile里面了。

4、记住以后只能用这个快捷方式启动才不用配置任何内容。

Firefox Portable 使用指南

Opera调用IE内核

opera右键的定制

Setp1：首先进入插件官网（http://www.meadco.com/neptune/download，并输入你的昵称和电子邮件地址，随后按“Continue”就可显示最终下载地址）下载MeadCo’s Neptune。然后在关闭Opera的情况下，安装此插件。

Setp2：打开Internet Explorer所在安装目录（通常是C:Program FilesInternet Explorer），并进入“plugins”子文件夹，找到并复制“npmeadax.dll”文件。然后将该文件直接粘贴到Opera安装目录下的“programplugins”文件夹中。

小提示：完成此操作后，启动Opera，然后在地址栏输入“opera:plugins”命令，查看Opera是否已经关联此插件MeadCo’s Neptune，如显示有MeadCo’s Neptune项目即表示已正确安装。

Setp3：接着打开如下页面：http://www.opera.com/support/search/supsearch.dml?index=415，并在该页面上找“View in IE”链接（如图1），然后鼠标拖动该链接至Opera工具栏上。释放鼠标按键之后，你就能在工具栏上看到一个新生成“View in IE”按钮。

有趣，有空仔细查一下这些术语的含义。

opera:config 找到 Rendering Mode

-1 表示适应窗口宽度默认对所有的窗口

其他方式(Opera 8.X 添加到 opera6.ini#User Prefs)

1) SSR = Small-Screen Rendering

2) CSSR = Color SSR

3) AMSR = Aggressive MSR

4) MSR = Medium-Screen Rendering

[Not yet implemented]

5) ERA = Extensible Rendering Architecture (ERA = SSR + CSSR + MSR + AMSR + a bit of magic)

都是地址栏历史纪录惹的祸，输入中文选择被挡在下面。这个问题已经困扰很久了

历史纪录太宽了

目前找到的办法

opera 地址栏输入

opera:config#UserPrefs|AutoDropdown

取消选择，然后保存。这样去掉自动的下拉菜单。
