+    *** DEVELOPER NOTE -- FIREFOX CONFIGURATION FOR TESTING ***
+    *
+    * If the URL bar starts with <b>file://</b>, Firefox may not load the font used
+    * to display the special characters used in the On-Screen Keyboard.
+    *
+    * To work around this Firefox bug, navigate to <b>about:config</b>
+    * and set <b>security.fileuri.strict_origin_policy</b> to <b>false</b>
+    * while testing.
+    *
+    * Firefox resolves website-based CSS URI references correctly without needing
+    * any configuration change, so this change should only be made for file-based testing.
+    *
