⚡ Chrome shows a "Read browsing history" warning for ALL tab management extensions. This is normal and required for our core features to work.

🩺 WHAT DR.BROWSER DOES
Dr.Browser keeps Chrome fast and efficient by detecting duplicate tabs, monitoring memory usage, and suspending tabs you haven't used — all without sending a single byte of your data anywhere.

⚡ KEY FEATURES
✓ Smart Duplicate Detection — Now with URL Normalization

Detects duplicate tabs even when URLs differ by tracking parameters (utm_source, fbclid, gclid, and more), fragments, http/https, or www prefix
Choose exactly which tab to keep — the most recently active tab is pre-selected
Pinned and active tabs are always protected

✓ Memory Usage Monitoring

Real-time system memory display
Identifies top memory-consuming tabs with color-coded indicators (High / Medium / Low)

✓ Intelligent Inactive Tab Management

Auto-detects tabs idle for 10+ minutes (configurable)
Auto-suspend frees RAM without closing tabs — restore them instantly by clicking

✓ Advanced Whitelist

Protect any site from auto-suspension
Supports plain domains (gmail.com), port-based dev servers (localhost:3000), subpaths (staging.myapp.com/admin), and regular expression patterns (/localhost:\d+/)

✓ One-Click Optimization

Close duplicates and suspend inactive tabs in a single action

✓ Privacy-First Design

All processing happens locally on your device
No servers, no tracking, no data collection

🎯 PERFECT FOR

Developers juggling multiple environments and localhost ports

❓ FREQUENTLY ASKED QUESTIONS
Q: Why does Chrome show "Read your browsing history"?
A: Chrome displays this warning for any extension using the "tabs" permission. It is required to see which tabs are open so we can find duplicates. We do not track or store your browsing history.
Q: What data do you collect?
A: None. Dr.Browser does not collect, transmit, or log any data. Everything stays on your device.
Q: Can you see what websites I visit?
A: Dr.Browser reads tab URLs only at the moment you open the popup or when the background alarm runs. We never log or store this information.
Q: Will auto-suspend lose my work?
A: No. Chrome's native tab discard preserves the tab in your browser — clicking it reloads the page. It is equivalent to the browser's built-in memory saving feature.
Q: What is the default suspend time?
A: 10 minutes of inactivity. You can change this to any value between 1 and 480 minutes in Settings.
