このアドオンはマルウェアの一種と言えるでしょう。
　このアドオンを導入すると、Amazonの商品ページを開いた際に「&tag=amzfinder-20」というパラメーターがURLの末尾に挿入されます。この状態でブラウザバックや再読み込みを行うとリンク切れとなり表示できません。
　このパラメーターはAmazonのアフィリエイトリンク（紹介コード）のようです。

無料で開発、提供しているのでなんらかの還元はあるべきです。しかしユーザーに説明をしていない、無関係の挙動を無断で行うべきではありません。

This add-on is a type of malware.
　After installing this add-on, when you open an Amazon product page, the parameter “&tag=amzfinder-20” will be inserted at the end of the URL. If the browser backs up or reloads the page in this state, the link will be broken and cannot be displayed.
　This parameter appears to be an Amazon affiliate link (referral code).

Since the site is developed and provided free of charge, there should be some kind of return. However, it should not be unauthorized and irrelevant behavior that is not explained to the user.

Doesn't work. Shorts still show up in Search-Unwatched.

This china spyware app doesn't block Youtube shorts or anything positive, it just needs access to everything so they can mine your personal information and feed you their amazon referral link.

Data miner tool. DO NOT USE

Data collector bollocks, forces you to use their amazon referral code and breaks the refresh function on amazon
