About this extension
Bull Tech gives you a real-time security and performance dashboard for every tab, directly in your browser toolbar. Built with zero external dependencies, no telemetry, and no data collection — everything runs locally.
🔍 Recon
Instantly shows the domain, port, tab IP (resolved via DNS-over-HTTPS), and your public IP. Manual refresh with live spinners.
📊 Monitor
Live CPU and memory usage for the current tab, updated every 2 seconds. Includes a one-click cache and storage cleaner.
🛡 Security Headers
Grades the site's HTTP security headers (A–F). Checks for CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy. Shows exactly what's missing.
🍪 Cookies
Lists and inspects all cookies for the current tab. Export as JSON, import and inject cookies, detect third-party trackers, block them at the browser engine level, and audit changes with snapshot diffing.
📷 Screenshot
Captures the full visible page and saves it as SVG or PDF with a save-as dialog.
⏸ Suspend
Frees memory by suspending inactive tabs. Supports auto-suspend timers, one-click resume, and a per-tab and per-domain whitelist.
