YesScript是我写的一个Firefox的扩展，允许用户有选择的屏蔽指定网站的JavaScript功能。虽然在Firefox选项对话框”Content”页面，用户通过选择”Enable JavaScript”打开或关闭JavaScript功能，但这种改变是针对所有网站，而不能选择性的屏蔽。
写YesScript的主要动力来自使用Google时的不便 – 用Firefox在登录Google后进行搜索，在返回的结果页面中，如果点击某个搜索结果的链接，Google会先把请求发送给自己(收集用户的选择偏好)，然后再重定向到目的站点。由于在国内访问Google.com的不稳定性，常出现由于Google自身响应速度慢导致链接打开速度慢；实在慢的时候，我一般在搜索页面里面Copy & Paste 搜索结果链接到另外一个tab窗口中打开，跳过Google的用户反馈收集 – 这些都是Google页面中的JavaScript代码造成的。

好在Firefox提供了选择性过滤JavaScript的支持，它同时提供了“白名单”和“黑名单”的功能，分别针对指定网址有选择的开放和关闭指定网站的JavaScript功能，但此功能并未开放给用户直接使用。NoScript是一个Firefox插件，它实现了JavaScript“白名单”功能，即仅允许某些网站开启JavaScript功能，其余全部禁止。有关“黑名单”的插件，我在Web上搜了一下，没找到，才决心自己写一个。为了和NoScript的名称相对应，这个插件叫做YesScript 
功能
YesScript是一个很简单的JavaScript“黑名单”插件，它的主要feature有：
- 添加自定义“黑名单”，屏蔽名单中网站的JavaScript功能；
- 功能开关，允许打开或者关闭YesScript，以便需要时临时恢复或者关闭JavaScript屏蔽功能；
- 中、英文界面，根据Firefox语言版本自动切换。
- 部署了远程更新RDF文件，供Firefox自动发现YesScript新版本并升级。
因为YesScript修改了Firefox的安全策略，所以任何改变，包括增加/删除黑名单上的站点；打开或者关闭YesScript都需要重启Firefox才能生效。

测试
我在Window XP (Firefox 1.5, 2.0) 和Ubuntu 6.1.0 (Firefox 2.0)上对YesScript进行了测试，均可正常工作。
考虑到公司知识产权相关规章制度，YesScript无法放到公网上下载，目前仅能开放给内部员工使用。

[...] While Googling around I found that someone else once made an extension called YesScript. It’s a single blog entry by a guy named Zhang Ling, and the install link is broken. It looks like his YesScript worked just like my YesScript, except his additionally has a global on/off button. I’ve tried to contact him, but got no reply. From a Babelfish translation: Considered the company intellectual property rights related rules and regulations, YesScript is unable to put to male on-line downloading, at present only can open for the internal staff uses.
