It's a good idea, but it sometimes leaves artifacts behind and sometimes (rarely) does almost nothing at all. Shortcut is nice.

really needs to work better in Firefox for Android. refuses to remove the "open in app" floating button or floating Whatsapp icon from at least Times of India.

バツボタンがないうざったい広告や、ログインを促す画面（インスタとかっていうハエが集まるサイト）を強制的に閉じることができるので有り難い。全自動で閉じる様になったらもっと良い。今後に期待。
