About this extension

NIFOBS Containers manages multiple isolated profiles directly in Firefox. Each profile runs in its own Firefox container with separate cookies and profile-scoped fingerprint behavior, helping prevent cross-profile session leakage.

This release focuses on production hardening, cookie format interoperability, and deterministic fingerprint consistency under real-world runtime conditions.

Key Features:

Create and manage isolated profiles (up to 100 profiles)
Automatic Firefox container provisioning per profile
Deterministic per-profile fingerprint identity (User-Agent, Canvas key, WebGL key)
Per-profile fingerprint ON/OFF control with hard-off behavior when disabled
Profile-scoped cookie snapshot and restore
Cookie editor with domain filter and output mode selection
Full JSON and Full String cookie editing
Compact JSON (header-only) and Compact String (header-only) compatibility modes
Automatic cookie format detection and normalization during save
Non-destructive partial cookie save behavior for mixed-validity inputs
Import/export profile data
Open all profiles and open by numeric range
Bulk close/reload/delete operations
Real-time progress notifications for long-running bulk actions

Developer comments

NIFOBS Containers is a privacy-focused profile manager that isolates cookies, localStorage, and fingerprint surfaces across browser containers.

Technical Details:

Uses Firefox contextualIdentities API for cookie/storage isolation
Uses deterministic profile-ID-based fingerprint derivation for stable cross-session behavior
Maintains per-profile fingerprint ON/OFF state and applies it consistently at runtime
Uses stricter profile import validation (object-map schema checks)
Supports cookie parsing and normalization from JSON and cookie-string input
Supports compact header-only cookie formats for external tool interoperability
Uses non-destructive partial apply when invalid cookies are mixed with valid entries
Uses debounced cookie snapshot handling on browser cookie-change events
Uses page-world spoofing patches for Canvas/WebGL/WebRTC/Geolocation with side-effect controls
Applies Canvas toDataURL mutation on an offscreen clone to avoid mutating original page canvas state
Registers fingerprint message listener early and supports both Promise and callback runtime.sendMessage patterns for robust bootstrap behavior
Stores all profile data locally via browser.storage.local
Performs all operations client-side only (no external telemetry or remote processing)
Requires webRequest/webRequestBlocking for profile-scoped request-header handling
Compatible with Firefox 140+ desktop and Firefox 142+ Android
