FuriKani oleh Lauchmelder

The simplest way to improve your Japanese reading experience if you are a WaniKani user. Supply the extension with a WaniKani API Token to automatically remove furigana on websites for any words you (should) know.

Vocabulary is automatically synchronized with WaniKani whenever you level up. So if you keep doing your reviews and level up you should slowly see more and more of the furigana disappear from the web. This way you will be forced to read words you know from memory, while still allowing you to see the pronounciation of unknown vocabulary.
