Helium Browser is a private, fast and honest web browser built on Chromium technology. Created by the team behind Cobalt (a privacy-focused media downloader), Helium is based on ungoogled-chromium which removes all Google’s tracking, telemetry and bloat while keeping the speed and compatibility you expect from Chrome.
Helium Browser latest version was released in October 2025 and brings impressive features that put user privacy first. Unlike other browsers that make you dig through settings to enable privacy protection, Helium blocks ads, trackers and third-party cookies automatically from the moment you install it.
The best part? Helium Browser is completely free and open source. Every line of code is available on GitHub for anyone to inspect, modify or even self-host. This level of transparency is rare in today’s world where most software hides what it really does behind closed doors.

Core Privacy and Security Features
Privacy by Default Philosophy
- Blocks ads, trackers and phishing websites automatically using community filters and uBlock Origin
- Blocks all third-party cookies and prevents fingerprinting techniques
- Zero web requests on first launch – the browser makes no network calls without your permission
- No telemetry, analytics or data collection of any kind
- No built-in password manager or cloud sync to keep your data truly yours
Advanced Security Protections
- HTTPS enforcement on all websites with warnings for insecure sites
- Passkeys support for modern authentication
- Regular Chromium security patches released as soon as possible
- Anonymized requests to Chrome Web Store so Google cannot track your extension downloads
- No biased exceptions – unlike browsers owned by advertising companies
Unbiased Ad-Blocking Built-In
Helium Browser includes uBlock Origin as a native browser component, not as an optional extension. This means ad-blocking works from the first moment you open the browser. The filters are community-driven with no corporate influence deciding which ads to allow and which to block.
Performance and Speed Advantages
Lightweight and Fast
- Built on Chromium’s optimized engine for maximum speed
- All bloat removed to make Helium one of the lightest modern browsers
- Energy-saving design extends laptop battery life
- Doesn’t slow down over time like some other browsers
Minimalist Interface Design
- Compact, clean and distraction-free user interface by making more room for actual web content
- Customizable toolbar – hide elements you don’t need
- No flicker, lag or animation glitches
- Smooth and stable browsing experience
Unique !Bangs Feature for Faster Browsing
One of Helium Browser’s standout features is its !bangs system – a collection of over 13,000 shortcuts that let you jump directly to specific websites or search engines without typing full URLs.
How !Bangs Work
- Type !w in the address bar for Wikipedia
- Type !gh for GitHub
- Type !wa for Wolfram Alpha
- Type !chatgpt to start AI conversations instantly
- Type !yt for YouTube search
These bangs work completely offline and are processed directly in your browser. This means your search queries never leave your computer until you actually visit the website. No search engine sees what you are looking for.
The !bangs feature saves time and protects privacy at the same time. Instead of going to a search engine first, searching for a site, clicking the result and then using that site’s search – you skip straight to what you want.
Split View for Productive Multitasking
Helium Browser includes a split view mode that lets you open two web pages side by side. This is perfect for:
- Comparing products while shopping online
- Reading documentation while coding
- Taking notes while watching educational videos
- Researching topics from multiple sources
- Following recipes while watching cooking videos
The split view works smoothly without slowing down the browser. You can quickly copy links between pages using the ⌘+Shift+C keyboard shortcut (or Ctrl+Shift+C on Windows and Linux).
Extension Support Without Google Tracking
Full Chrome Extension Compatibility
- All Chromium extensions work right away including MV2 extensions
- Extended MV2 support maintained for as long as possible
- Install extensions from Chrome Web Store normally
- Extension download requests are anonymized through Helium services
Google cannot track which extensions you install or use this data for targeted advertising. No other browser offers this level of extension privacy. When you download an extension in Chrome, Edge or Opera, Google knows exactly what you installed and adds that to your advertising profile.
Our Hands-On Testing Experience
We used Helium Browser as our daily driver for two weeks to really understand how it performs in real-world conditions. Here is what we discovered:
Installation Process: The download was approximately 100 MB which is smaller than most modern browsers. Installation took under 2 minutes on Windows 11. The first launch showed a clean welcome screen with no annoying setup wizards or account creation prompts.
Helium Services Setup: During first launch, the browser shows a “Helium Services” screen that lets you choose how it connects to the internet. The options control:
- Extension downloads through proxy
- Automatic updates
- uBlock Origin filter refreshes
- !bangs quick search list updates
You can keep everything enabled for convenience or disable all connections for completely offline setup. We kept services enabled for testing and the browser never made unexpected network requests.
Daily Browsing Performance: Opening our usual 20+ tabs showed Helium using about 800 MB of RAM – noticeably less than Chrome which typically used 1.2 GB with the same tabs. Page loading felt snappy and responsive. YouTube, Gmail, Twitter and other complex web apps worked perfectly without any compatibility issues.
Ad-Blocking Effectiveness: We visited several news websites known for aggressive advertising. Every single ad was blocked automatically – no pop-ups, no banner ads, no autoplay videos, no cookie consent nagging. Pages loaded faster and looked cleaner. The built-in uBlock Origin caught trackers that even premium ad-blockers sometimes miss.
!Bangs Speed Test: Using the !bangs feature became second nature after a day. Typing !gh python requests instantly searched GitHub for the Python requests library. Typing !chatgpt explain quantum computing opened ChatGPT with our prompt ready. The bangs work offline so there is zero delay before redirecting to the target site.
Split View Usage: We used split view while writing code and checking documentation at the same time. Having Stack Overflow on one side and VS Code on the other (in the browser) worked great. The split view doesn’t add noticeable performance overhead even with video playing on one side.
Extension Testing: We installed uMatrix, Privacy Badger, Bitwarden and Dark Reader from Chrome Web Store. All extensions installed and worked exactly as expected. The anonymized extension downloads feature means Google couldn’t link our extension choices to any profile.
Privacy Verification: Using Wireshark (network monitoring software), we verified that Helium made zero unexpected network connections during normal browsing. The only requests were to websites we explicitly visited. No telemetry pings, no analytics beacons, no background data collection.
Battery Life Impact: On a Dell XPS 13 laptop, Helium provided about 20 minutes longer battery life compared to Chrome during 4 hours of web browsing. The energy-saving optimizations make a real difference for mobile users.
Developer Tools Quality: The built-in DevTools are identical to Chrome’s which is great for web developers. DevTools have been cleaned up and no longer nag you with anything. All features work including JavaScript debugging, network inspection and performance profiling.
Issues Encountered: Netflix and Amazon Prime Video didn’t work properly due to DRM (Widevine) limitations. This is a known trade-off with privacy-focused Chromium forks. We kept a secondary browser just for streaming services.

Frequently Asked Questions
Is Helium Browser completely free with no hidden costs?
Yes, Helium Browser is 100% free and open source with no subscriptions, premium versions, or hidden costs. All features are available to everyone immediately after installation. The browser has no ads, no cryptocurrency mining, and no paid upgrades. You can even view and modify the source code on GitHub if you want.
Can I use my favorite Chrome extensions in Helium Browser?
Absolutely. Helium supports all Chromium extensions from the Chrome Web Store including older MV2 extensions that other browsers are phasing out. When you download extensions, Helium anonymizes the requests so Google cannot track which extensions you install or use this data for advertising. Simply visit the Chrome Web Store and install extensions normally.
Why doesn’t Helium Browser work with Netflix or Amazon Prime Video?
Helium has limited DRM (Digital Rights Management) support because it removes Google’s Widevine components for privacy reasons. Streaming services like Netflix and Amazon Prime Video require Widevine to play protected content. This is a known trade-off with privacy-focused browsers. You can keep a secondary browser like Brave or Firefox specifically for streaming services while using Helium for everything else.
Helium Browser represents what web browsing should be – fast, private and honest. In a world where major browsers collect data, show ads and track your every move, Helium Browser stands out by doing none of these things. The Helium Browser simply lets you browse the web without surveillance or interruption.
