Tab Leak Guard by Cameron Amer

Tab Leak Guard helps you investigate tabs that keep growing while you browse. It observes sustained live-page growth and explains the evidence behind each finding.

• Start a temporary 15-minute session, monitor selected sites, or authorize all regular websites.
• Review evidence quality, freshness, and the reasons a tab looks concerning.
• Receive optional notifications with generic text by default.
• Snooze findings, ignore sites, or stop monitoring whenever you choose.
• Review an exact unload or reload action before confirming it.

Analysis and history stay in Firefox. There are no accounts, analytics, or automatic data uploads. The extension does not read page text or form values.

Detection is heuristic. Firefox does not expose exact per-tab memory through this extension’s APIs, and some leak types are not observable. Allow about five minutes for learning. Version 0.1.1 requires confirmation for every recovery action; automatic recovery is unavailable. This is an experimental release.
