uBlock Origin Beta
for Microsoft Edge

pronounced you-block origin (/ˈjuːˌblɒk/) — you decide what enters your browser.

An efficient blocker add-on for Microsoft Edge. Fast, potent, and lean.

Note: This port of uBlock Origin to Microsoft Edge is in early development

While most of the code in this extension is shared with upstream, the platform layer is not finished and there is no guarantee of stability, performance, or complete feature parity until the extension is published on the Microsoft Store.


Known issues, bugs and missing features are listed on the Issues page for this repo. Features documented in the upstream extension and not listed on the Issues page are assumed to be working. If you run into an issue not listed, please create a new issue and complete the provided template.

Performance and Efficiency

Early tests of performance of this extension on the Microsoft Edge browser are positive, though more are required to share useful data here. This fork shares the majority of its code with the Chrome and Firefox versions which have been proven to be faster than AdBlock Pro.


You can download a Preview Release from the Microsoft Store.

To install beta releases directly from GitHub, you will need to side-load the extension:

  1. Download the latest release from the Releases page
  2. Extract the zip file somewhere safe (it will need to remain there as long as you use the extension)
  3. Browse to about:flags in Edge and turn on the option Enable extension developer features
  4. Restart your browser
  5. Go to Extensions in the browser menu and click Load extension
  6. Select the uBlock0.edge folder you extracted earlier

Edge disables side-loaded extensions whenever you restart the browser. However after a few seconds you will get a prompt to re-enable them with a single click.


To benefit from uBlock Origin's higher efficiency, it's advised that you don't use other inefficient blockers at the same time (such as AdBlock or Adblock Plus). uBlock₀ will do as well or better than most popular ad blockers.
