Nit: variable should not have typically have verb names. So action_box_enabled
would be better.

Done.

Nit: If an if statement is less than two lines total, it does not require
braces.

You can simplify this logic somewhat:

bool default_value = !action_box_enabled;

ExtensionPrefs* prefs = ...
if (!prefs)
  return default_value;

bool value;
if (!prefs->GetBoolean(name, &value))
  return default_value;

return value;

Since you are checking this in multiple places, can you please add a function to
extension_switch_utils.*, and call that function instead?
