Wordle Hard Mode Helper

Prevents you from using letters that are known to be incorrect.

An open-source extension that keeps you from playing a letter that you've already played that is not in the word. When you type or click a letter, the extension will check if that letter has already been played and marked as not in the word. If it has the backspace key will be triggered removing the letter.
