FreeKeep：自动领取 Steam 限免游戏

Automatically claims limited-time free-to-keep Steam games and DLC in the background, using the Steam login already in this browser. No password, no access to your login cookie, no server, no data collected. Open source (MIT).

Why it's safe

• Reuses your browser session. Once you're signed in to the Steam store, Firefox attaches your session to requests to the store. FreeKeep only sends the same request as Steam's Add to Account button.
• Can't read your credentials. Steam's login cookie is HttpOnly, so no add-on can read it, and FreeKeep doesn't ask for the cookies permission.
• No server. No backend, no analytics, no tracking. Nothing is uploaded or collected.
• Verifiable. In about:addons, FreeKeep asks only for notifications and access to store.steampowered.com; optional features stay off until you turn them on. The source code is public.

Features

• Claims only genuine limited-time free-to-keep promotions; demos, playtests and free-to-play games are excluded
• Skips games you already own, and claims DLC only if you own the base game
• Uses your Steam store region, so it claims only what's free where you are
• Checks every 1, 3, 6, 12 or 24 hours, and when the browser starts
• Claims automatically, or asks you first
• Notifies you only when a game is claimed or needs your attention
• Handles Steam's 24-hour web login: renew it with one click, automatically (optional permission), or just get a reminder
• Pixel-art look in Steam colours, with a chest icon in colours you pick
• Optional Epic Games Store reminders: tells you about Epic's free games so you can claim them on Epic's site. Off by default; the public list is read without signing in
• 12 languages, about 45 KB of code, no dependencies

Sign in to the Steam store in Firefox and FreeKeep runs on its own.
