BballHQ for Yahoo Fantasy

A browser extension that brings your Yahoo leagues into BballHQ, using your Yahoo login in this browser.

Download the zip and unzip it. You get a bballhq-extension folder; keep it somewhere it won’t be deleted.
Open chrome://extensions (Edge: edge://extensions) and turn on Developer mode.
Choose “Load unpacked” and pick the bballhq-extension folder.
Sign in to Yahoo in the same browser, then open My league.

Reads only: Your Yahoo Fantasy leagues, rosters, matchups and stats. It can’t change your teams.
Only for BballHQ: It answers bballhq.com’s pages and no other site.
Stays with you: Synced leagues are kept in this browser. Nothing from Yahoo goes to our server.
Browsers: Chrome, Edge, Brave and Arc on a computer. Not Safari, Firefox or phones.

To update, download it again, replace the folder’s files, and click the reload button on the extension in chrome://extensions.
