urlclassifier3.sqlite是Firefox3生成的反钓鱼数据库,而urlclassifier2.sqlite则是Firefox2的反钓鱼数据库.

urlclassifier3.sqlite位于“D:\Documents and Settings\Administrator\Local Settings\Application Data\Mozilla\Firefox\Profiles\随机字符串.default\urlclassifier3.sqlite”

而urlclassifier2.sqlite位于“D:\Documents and Settings\Administrator\Application Data\Mozilla\Firefox\Profiles\随机字符串.default”

 

不过Firefox3生成的这个数据库的体积有点吓人，比如我安装的Firefox生成的urlclassifier3.sqlite达到了53M，而且还有增长的趋势。

在查看了MozillaZine Knowledge Base知识库后，发现这个数据库是Firefox3从Google的一个服务中获取的(可以在about:config中查找“urlclassifier.keyupdatetime”)：

https://sb-ssl.google.com/safebrowsing/newkey

而且发现有个参数“urlclassifier.updatecachemax”应该是控制urlclassifier3.sqlite文件的大小的：

Firefox incorporates the Google Safe Browsing extension in its own Phishing Protection feature to detect and warn users of phishy web sites.

In Linux, the periodic updates for the blacklist caused significant amounts of disk activity due to index and cache sizes for the underlying SQLite database. This preference controls a maximum cache size for SQLite that cuts down on the amount of disk activity required during an update.

Maximum size of the SQLite cache during an update, in bytes. Default in Linux is 104857600 (100 MB); elsewhere, -1 (SQLite default).
