Automatic Tab Discarder 作者： ChaoticOrder

Tab Discarder keeps Firefox running smoothly by automatically unloading tabs you haven't used in a while. Discarded tabs remain visible in your tab bar and reload instantly when you click them — you won't lose any history or bookmarks.

🔧 FEATURES

• Automatic discard — inactive tabs are unloaded after a configurable time (5–120 minutes)
• Manual discard — one click to free up memory from all eligible tabs right now
• Live stats — see how many tabs are open, asleep, or eligible for discarding
• Pinned tab protection — pinned tabs are never discarded (optional)
• Audio protection — tabs playing music or video are never discarded (optional)
• Lightweight — runs quietly in the background, checks once per minute
• No data collection — this extension does not collect, transmit, or share any data whatsoever

💡 HOW IT WORKS

When a tab hasn't been active for longer than your chosen threshold, Tab Discarder unloads it from memory. The tab title and favicon stay visible in the tab bar. Clicking the tab reloads it normally. This is the same mechanism Firefox uses natively — Tab Discarder just gives you control over when and how it happens.

🔒 PRIVACY

Tab Discarder requires only the permissions it needs: tab access (to detect activity and discard tabs), storage (to save your settings), and alarms (to check tabs on a schedule). No browsing data ever leaves your browser.
