Firefox 2.0 incorporates the Google Safe Browsing extension in its own Phishing Protection feature to detect and warn users of phishy web sites.

Under under “Tools → Options → Security / Tell me if the site I'm visiting is a suspected Forgery” are two radio options, corresponding to the value of browser.safebrowsing.remoteLookups:

  • Check using a downloaded list of suspected sites
  • Check by asking [provider] about each site I visit

The first choice is the default in Firefox. When it is selected, and Safe Browsing is enabled, the application periodically checks for the provider for updates and adds them to a database, stored in urlclassifier2.sqlite.

Possible values and their effects

The urlclassifier.keyupdatetime.* and urlclassifier.tableversion.* preferences do not exist by default. They are set by the application and used to control updates.

The application sets various urlclassifier.keyupdatetime.* and urlclassifier.tableversion.* values to record the timestamps and version numbers of downloads from the Safe Browsing provider.

For example:

  • urlclassifier.keyupdatetime.https://sb-ssl.google.com/safebrowsing/getkey 1182290217
  • [7 others omitted]
  • urlclassifier.tableversion.goog-white-url 1.371

Has an effect in

  • Mozilla Firefox 2.0 and above.
