はちまバスター is a browser add-on for Chrome that disables links to はちま and JIN websites. When a link contains the URL of either はちま or JIN, it is automatically disabled. Users can also add any other websites to the filter through the right-click menu or options.

The add-on offers additional settings, including the option to hide censored search results on Google and to not display tweets containing censored links on Twitter.

The latest version, 0.20.6, ensures that the add-on does not crash on Discord. However, the dynamic switching between enabled and disabled states is not available on Discord, and clicking on "censored" opens the image.

Overall, はちまバスター is a useful add-on for Chrome users who want to disable links to はちま and JIN websites, providing customizable options to enhance their browsing experience.
