CS2 Trader is a Chrome/Firefox extension that adds trade-lock countdowns, in-browser skin inspection without launching the game, and Doppler/Gamma Doppler phase and fade-percentage detection. It pulls float values and pricing from multiple sources directly into your Steam inventory and trade offers, so you know an item's real worth before accepting a trade. Open-source, used by 300,000+ CS2 traders.

The extension needs access to steamcommunity.com pages (inventory, trade offers, market) to inject pricing, float data and the inspect button — a standard permission set for this type of tool.
