+You can further refine results to only localization files by using specific localization file extensions in the `Path filter` field in the top right:
+* For Firefox: limit the search to `.ftl` or `.properties` files. You can find information on the file from its [CONTEXT](../pontoon/ui.md#context). Or you can use `{.ftl,.properties}` to only show files with those extensions.
+* For Android: limit the search to `.xml` files.

 #### Context
 
-Sometimes you may want to investigate more context about a particular string through an external resource such as a [Version Control System](glossary.md#version-control-system). The `CONTEXT` information provided underneath the source string shows the identifier, file, and project for the string - allowing you to find the string within the codebase of the project. For example, for some Mozilla projects these can be used to [track strings to bugs](../mercurial/tracking_back_string_to_bug.md).
