It is still possible for websites to access indexedDB by using Web Workers:
new Worker("data:application/javascript,console.log('indexedDB: ', indexedDB)")
This works since userscripts only run in top-level websites and frames, but the above code runs JS code in a seperate thread with no attached DOM.
