I think you don't use DictionaryValue or ListValue.  If so, please remove.

[Alexandre Abreu, 2012/04/13 21:52:38]

Done.

File path is declared both inside namespace base and outside of any namespace. 
Looking at other files (grep 'class FilePath'
~/cr/gitMac/src/chrome/browser/extensions/ ), I think the convention is to use
FilePath over base::FilePath.

[Alexandre Abreu, 2012/04/13 21:52:38]

yes, from what I see

+
+// Provides various utility functions for external extension manipulation.
+class ExternalExtensionUtil {
+ public:
+  static base::DictionaryValue* ExtractPrefs(const FilePath& path
+                                         , base::ValueSerializer* serializer);

Style nit: comma belongs on the previous line, and indentation should make
"const" and "base::" start in the same column.

[Alexandre Abreu, 2012/04/13 21:52:38]

Done.
