SteamDB is a Firefox extension designed to enhance the shopping experience on Steam. It provides users with essential features such as displaying the lowest recorded prices across all currencies and offering detailed price history for games. Additionally, it shows concurrent player counts and peaks, alongside the latest game updates, making it easier for users to stay informed about their favorite titles. The extension also simplifies navigation by adding links to SteamDB across various Steam sites and providing quick sell buttons in inventory.

Beyond these functionalities, SteamDB allows users to skip age checks on the Steam store, automatically accept market agreements, and remove link filter links. It highlights owned games, DLCs, and packages, making it easier for users to manage their libraries. Furthermore, it supports wishlisting, following, and ignoring games directly from steamdb.info, positioning itself as a simpler and faster alternative to similar tools like Enhanced Steam and Augmented Steam.
