Here are the links to access the links to download either the Chrome or Firefox Elite Fantasy Basketball extensions.
The Draft Tracker requires an extension if you are drafting on either Yahoo or ESPN. Those with leagues on Fantrax DO NOT need to download an extension.
The other tools that connect to your league (Daily Projections, Projected Standings, Matchup Tool, etc.) only require an extension if you are playing on Yahoo. ESPN users DO NOT need an extension for any tool besides the Draft Tracker. Fantrax users DO NOT need an extension to use any of the tools.
