Overview

Rinswa Browser is a next-generation web browser engineered for users who value aesthetic refinement, absolute privacy, and uncompromised performance. Powered by the modern, battle-tested Mozilla Gecko engine, Rinswa completely removes sponsored telemetry, invasive data collection, and distracting commercial bloat, replacing them with a sleek Cyber-Glass visual theme, native ad blocking, and customizable privacy controls.

Key Features

🎨 Cyber-Glass & Multicolour Ribbon UI

• Signature Visual Identity: Designed with a vibrant, translucent glass aesthetic, custom window controls, and the signature Rinswa glossy multicolour ribbon emblem.
• Modern Tabstrip & Navigation: Streamlined tabs, refined omnibar, and responsive UI micro-animations tailored for Windows 11 and modern desktop environments.
• Alpine Sunset Theme & Wallpapers: High-resolution dynamic backgrounds crafted for new tab and start experiences.

🛡️ Privacy & Security First

• Zero Hidden Telemetry: All internal telemetry is disabled at compile time (--disable-telemetry), and crash reports to external servers are completely neutralized.
• No Sponsored Content: Absolutely no sponsored tiles, sponsored shortcuts, activity stream ads, or affiliate link injection.
• Strict Anti-Tracking: Upstream Enhanced Tracking Protection (ETP) enabled out-of-the-box with strict third-party cookie isolation and fingerprinting protection.
• HTTPS-First Enforcement: Encrypted connections prioritized across all web navigation.

⚡ Out-of-the-Box Native Ad Blocking

• Pre-Integrated uBlock Origin: Comes bundled directly with Raymond Hill's industry-leading uBlock Origin extension in the distribution folder, giving you instant, lightweight, and effective ad and tracker blocking on your first launch.

📑 Native Smart Tab Management & Clean Tabs

• Automatic Tab Grouping: Automatically organizes heavy multitasking sessions into structured categories:
  • Work / Dev: Laravel, GitHub, Stack Overflow, Documentation, Notion, Figma
  • Shopping: Amazon, Flipkart, Product reviews, shopping carts
  • Personal: Gmail, YouTube, WhatsApp Web, social feeds
  • Media & Streaming & Docs & Research
• Duplicate-Tab Detection: Identifies exact URL clones and normalized path duplicates across all windows.
• Sleeping Tabs: Proactively hibernates inactive tabs using native discard APIs to drop RAM instantly.
• Smart Workspaces: Save any tab group as a persistent workspace and restore it later with one click.
• Signature "Clean Tabs" Engine: Instant automated audit (e.g. "You have 47 tabs: 12 duplicates, 8 inactive for >7 days, 4 YouTube tabs") with [Clean Automatically] and interactive [Review] checklist modes.

🚀 Cutting-Edge Engine Performance

• Gecko 157.0.1 Stable Engine: Full support for the latest web standards, WebAssembly, WebGPU, and modern CSS features.
• Hardware-Accelerated WebRender: Butter-smooth rendering and low GPU memory utilization.
• Process Sandboxing (Fission): Full site isolation architecture ensuring untrusted sites cannot access data across tabs.

Building from Source

For a complete, step-by-step walkthrough on building the installer, merging upstream Firefox engine updates, and publishing releases, see the Updating & Building Guide.

Prerequisites

To compile Rinswa Browser on Windows, ensure the following are installed:

1. Windows 10 / 11 (64-bit)
2. MozillaBuild 4.0+ (installed at default path C:\mozilla-build\)
3. Visual Studio 2022 Build Tools (C++ Desktop Development workload and Windows 10/11 SDK)
4. Git for Windows and Python 3.11

Quick Build (One-Click)

The simplest way to build Rinswa is using the preconfigured Windows batch script:

1. Double-click Build-Rinswa-Stable.bat (or launch via PowerShell / Command Prompt):

   .\Build-Rinswa-Stable.bat

2. The automated pipeline will:
   • Generate all multi-resolution branding assets and .ico files.
   • Configure the environment via MozillaBuild.
   • Compile the full Gecko engine using 16 parallel compilation threads (-j16).
   • Bundle uBlock Origin into the application distribution.
   • Package the standalone release installer (.exe) into rinswa-stable\obj-rinswa\dist\install\sea\.

Advanced Build via Command Line

You can also run specific pipeline phases using scripts/build-stable.sh inside the MozillaBuild MSYS2 shell:

# Enter MozillaBuild environment
C:\mozilla-build\start-shell.bat

# Navigate to project directory
cd /c/Users/arind/OneDrive/Documents/Project/browser

# Available phases: bootstrap | prepare | compile | package | all
./scripts/build-stable.sh compile

---

Release Outputs

Once compiled, build artifacts are located in:

• Standalone Installer: rinswa-stable\obj-rinswa\dist\install\sea\Rinswa.Setup.exe
• Portable Distribution: rinswa-stable\obj-rinswa\dist\bin\ (Run via rinswa.exe)

---

Privacy & Security

Rinswa's default network policy ensures complete user sovereignty:

• No telemetry transmission: Telemetry servers and pings are stripped.
• Zero user profiling: No browsing patterns or history are monitored or externalized.
• Cryptographic verification: Reuses standard Mozilla certificate revocation (OCSP) and SafeBrowsing threat blocklist updates to ensure real-time protection against malicious websites.

For details, refer to the Rinswa Privacy & Security Documentation.
