A Firefox Extension to remove Bullet Games from lichess.org. Optionally remove Blitz Games and Puzzle Variants.
Bullet Games are addictive - this Firefox extension removes all options to launch a Bullet Game on lichess, stopping you from wasting your time by chasing the next dopamine push.
You can download the extension here.
If the extension does not work right away, you may have to allow the extension to always access lichess.org instead of "Only when clicked".
The extension has an options page where you can configure the settings. Go to about:addons to set your preferences.
