+# Firestore fullscreen (Chrome extension)
+
+Get a fullscreen experience when browsing the Firestore database.
+
+Have you ever spent time browsing the firestore database and wondered why the 3 columns section had to be on such a small screen area? 
+This extension adds a button in the interface which toggles fullscreen mode. When in fullscreen mode, the 3 columns table takes the whole screen area so that you can browse easily. Click again on the button to exit the fullscreen mode and get back to normal.
+
+No data is read or collected, the extension only adds the button and changes some CSS properties.
+Full source code is available here: https://github.com/clementlize/firestore-fullscreen
