Browser Breather

A safe, calm tab hibernator that keeps your browser fast without breaking your flow.

Browser Breather is a calm, Manifest V3 tab hibernator that keeps Chrome fast without nagging you, spying on you, or breaking important tabs. What it does • Uses the browser’s built-in tab “discard / hibernate” feature – it never closes tabs or shows its own replacement page. • After a delay you choose (5–120 minutes), inactive tabs are gently put to sleep to free memory and CPU. • A single button lets you “Hibernate inactive tabs now” whenever you want a quick clean-up. Safe by default • Protects active, pinned, audio-playing and internal/browser pages. • “Never sleep these sites” allowlist for critical tools like email, docs, music, etc. • Tabs stay in your tab bar and simply reload when you click them – nothing important is silently closed. Trust & privacy • No host permissions. • No content scripts, no analytics, no ads, no remote servers. • All settings and tab timestamps are stored locally in your browser only. Good for • People with way too many tabs open. • Laptops that feel sluggish with lots of sites. • Anyone who wants a simple, quiet alternative to noisy or over-complicated tab managers. Browser Breather v1 focuses purely on safe auto-hibernation. Future updates may add optional workflow features (profiles, focus modes, etc.) while keeping the core experience calm and privacy-friendly.
