About this extension
Prefire is a free companion for FACEIT in Counter-Strike 2. It puts the numbers you look up before every match right into FACEIT's match room. If you turn them on, it can also make the clicks you make every match. And it connects FACEIT to Prefire's demo study.

Free, in the match room
  • Every player's level, Elo, K/D, win rate and last five results over their last 30 matches, right on their own card. Open it for K/R, ADR, headshots, average kills, and how they do on the map you're about to play.
  • Each team's average Elo and level and its chance to win. On your team's line, the Elo a win or a loss is worth for you (an estimate).
  • Your own Elo, what you still need for the next level, and your session over the last 12 hours.
  • The same last-30 panel on any player's profile.
  • Focus mode, off until you turn it on, hides the match room's chat, ads, promotions and stream widgets while you play. Accept, Ready, the map veto and Connect are never hidden.

Free automations, off until you turn them on
  • Accept matches: after a pause you choose, with an optional sound and notification.
  • Accept party invites: only from players on your own list, or from anyone.
  • Connect to the server: presses FACEIT's Connect once, when the server is ready.
  • Map and server veto: bans in your own order when it's your turn.
  • Copy server details: copies the server's connect command for the CS2 console.

Before acting, each waits about as long as a person would. It clicks only FACEIT's own button for the job, at most ten times a minute. It never acts after you already have, and it stops at a captcha or an anti-bot check. One switch in the toolbar pauses them all. They act only on your own account.

Prefire's demo study (a free trial, then the Solo plan)
  • A Study badge on every player in your match room opens their last match on the room's map in Prefire's web study.
  • FACEIT's Watch demo button sends the demo straight to Prefire instead of your Downloads folder.

Your data

FACEIT's stats are read in your browser, with your own FACEIT sign-in, and none of them is sent to Prefire. Prefire's servers are contacted only for the demo study, and only while you're signed in to Prefire. When you install it, Firefox tells you what leaves the browser for that: your Prefire sign-in, and which match rooms you open and which Study buttons you press. No ads, no analytics, no tracking.

In English and Brazilian Portuguese. Not affiliated with FACEIT or Valve.
