How to Install CSGO Trader on Chrome or Firefox

Updated

CSGO Trader is an open-source browser extension for Chrome and Firefox designed to help with CS:GO trading. To install it, open csgotrader.app and use the Install section on the site, choosing the build for your browser. The site does not list a price, so treat cost and any account or login requirements as unconfirmed until you check the install page itself.

What You Need Before Installing

  • A desktop browser: Chrome or Firefox (the two browsers named on the site).
  • Access to csgotrader.app — the site is a JavaScript app, so JavaScript must be enabled for the page to load.
  • A Steam account you normally use for trading, since the extension works on Steam inventory, market, and trade offer pages.

Installation Steps

  1. Go to csgotrader.app.
  2. Find the Install section on the page.
  3. Select the option for your browser (Chrome or Firefox).
  4. Follow the browser's extension install prompt to add it.
  5. Confirm the extension appears in your browser's extension list or toolbar.

Expected result: The extension is active, and its features appear when you browse Steam inventory, market, and trade offer pages.

How to Verify It's Working

Open a Steam inventory or trade offer page and check for signs the extension is running, such as pricing info on items, total inventory or trade offer value, or float and other technical item details. If you see none of these, the extension is likely not enabled for that page or not installed correctly.

Common Stumbling Blocks

  • Blank or non-loading site: The page needs JavaScript enabled; without it, the app will not render.
  • Wrong browser build: Make sure you picked the Chrome or Firefox version matching the browser you actually use.
  • No visible changes on Steam: Confirm the extension is enabled, then reload the Steam page.

What You Get After Installing

The extension's feature list includes pricing info in inventories and trade offers, total inventory and trade offer value, profit display for incoming offers, mass listing/selling, trade-lock countdowns, float and pattern details, Doppler phases and fade percentages, market sorting by float, an NSFW filter, item bookmarks with trade-ready notifications, CSGOLounge and CSGOTraders auto-bumping, multiple pricing providers, instant accept/decline buttons, and a currency converter and percentage calculator in the popup. The site describes this as an incomplete list, so expect more than what is named here.

Because the project is open source, you can review its code and release notes through the Changelog and Release-Notes links on the site if you want to check what changed in a given version before updating.
