A WebExtension can request access to local files without the warning prompt
stating that the extension will “Access your data for all websites” being
displayed to the user. This allows extensions to run content scripts in
local pages without permission warnings when a local file is opened. This
vulnerability affects Firefox ESR < 60.3 and Firefox < 63.
