Lichess hide Elo — Jörg Zieren

Did you ever play overly careful against a higher rated player? Or too careless against a lower rated player? This extension hides Elo ratings on the lichess.org website so they cannot influence your play. No ratings will be shown in the seek list or in the game. The extension can be toggled on or off with a single click.

NOTE: Lichess has since added a user preference to hide ratings, making this extension largely obsolete. However, the extension can toggle ratings on/off with a single click in the address bar. The Lichess user preference requires you to navigate to the preferences submenu, which is not what you want during a game. On the other hand, the Lichess preference will (probably) always work, whereas the extension can be broken by (even invisible) changes to the Lichess website.

For now the extension will continue to be available, but if (or rather, when) Lichess makes breaking changes it may be unpublished.
