## Description

<strong>Give every Firefox Container its own proxy route, request headers, and host access rules.</strong>

Privacy Containers turns one Firefox window into a controlled workspace for web security testing, intercepting proxy workflows, and multiple authenticated accounts.
<ul><li>Route each container directly or through reusable HTTP, HTTPS, or SOCKS proxies.</li><li>Use remote DNS, HTTP/HTTPS proxy authentication, localhost bypasses, and per-proxy exceptions when needed.</li><li>Add global or per-container request headers, including the PwnFox-compatible X-PwnFox-Color header.</li><li>Keep target hosts inside approved containers with Host Rules, then reopen blocked links in the right context.</li><li>Open, reopen, move, and pin tabs with configurable keyboard shortcuts.</li><li>Clear cookies and page storage directly from the toolbar.</li></ul>
Route one client session through Burp Suite, Caido, OWASP ZAP, or another intercepting proxy; keep a second account direct; and leave everyday browsing untouched.

<strong>No account, telemetry, cloud service, or remotely loaded code. Settings stay in Firefox, and traffic uses only the proxies you configure.</strong>
