BrowserOS supports full ad blocking through uBlock Origin, the most effective open-source ad blocker available.

​
How It Works

Chrome has been phasing out support for Manifest V2 extensions, which uBlock Origin relies on for its full blocking capabilities. We re-enabled Manifest V2 support in BrowserOS so uBlock Origin can run at full power. Install it from the Chrome Web Store: uBlock Origin

​
BrowserOS vs Chrome

We ran both browsers through adblock.turtlecute.org, a test that measures how effectively a browser blocks ads and tracking scripts.

BrowserOS — 68%

BrowserOS blocking 68% of ads

Chrome — 7%

Chrome blocking only 7% of ads
Out of 133 ad-related requests:
  • BrowserOS blocked 91 (68%)
  • Chrome blocked 9 (7%)
That’s roughly 10x more protection with zero configuration.

​
What This Means

Fewer ads means faster page loads, less bandwidth usage, and significantly reduced tracking. BrowserOS handles this natively so you can focus on browsing.
