Arc for desktop is a Chromium-based browser and is compatible with Chrome extensions, including ad blockers like uBlock Origin.
Google is introducing an updated Chromium extension specification, Manifest V3, that may change how ad blocking extensions work.
Ad blocking extensions using the older Manifest V2 specification will continue to function in Arc for desktop as late as June 2025.
We believe it's vital to always support some form of ad and tracker blocking, which is why we're building a native ad blocker for Arc for desktop.
