How to add uBlock Origin to Edge

To add uBlock Origin to Edge, open the Microsoft Edge Add-ons store, search for uBlock Origin, select Get, then select Add extension.

This guide covers the install, what to check first, the Chrome Web Store and uBlock Origin Lite, the settings worth changing, updates, and fixes when the install fails.

Step-by-Step Guide to Adding uBlock Origin to Microsoft Edge

uBlock Origin is listed in Microsoft's own Edge Add-ons store, so desktop Edge needs no change to its store settings.

1. Open Microsoft Edge on your computer.
2. Select Extensions to the right of the address bar, then select Get Extensions for Microsoft Edge.
3. Search the Edge Add-ons store for uBlock Origin.
4. Select the uBlock Origin extension in the results and check the listing is by Raymond Hill.
5. Select Get to add it to Edge.
6. Review the permissions, then confirm with Add extension to install.
7. Select Extensions again to see uBlock Origin and manage its settings.

If the Extensions button is missing, open Settings and more > Extensions instead.

Pre-requisites for Installing uBlock Origin on Edge

Requirement	What to check
Update Microsoft Edge	Select Settings and more > Help and feedback > About Microsoft Edge. Edge also updates itself on restart
Enable extension support	Extensions are on by default in desktop Edge. A work or school PC can block them by policy
Use a compatible version of Edge	The current desktop Edge on Windows or macOS. uBlock Origin is a Manifest V2 extension, which Edge still runs for now
Stable internet connection	Needed to download the extension and its filter lists
Basic knowledge of extension installation	Knowing where the Extensions button and Manage extensions page are is enough

uBlock Origin or uBlock Origin Lite: which should you install?

Chrome stopped running Manifest V2 extensions with Chrome 139, and the Chrome Web Store removed them. Edge has not reached that point yet.

Your situation	Install this	Why
Desktop Edge, personal PC	uBlock Origin from Edge Add-ons	The full extension is still listed and runs in Edge
You want the Manifest V3 version that will outlast the phase-out	uBlock Origin Lite	A Manifest V3 build by the same developer, published on the Chrome Web Store
Managed work PC from early 2027	uBlock Origin Lite	Microsoft expects Manifest V2 deprecation for enterprise customers to begin then
Chrome	uBlock Origin Lite	Chrome 138 was the last version to support Manifest V2 extensions
Firefox, including Firefox for Android	uBlock Origin from Firefox Add-ons	The full extension is listed for both

Install from the Chrome Web Store

Edge can install extensions from the Chrome Web Store. The full uBlock Origin is no longer listed there, so this route installs uBlock Origin Lite.

1. In Edge, navigate to the Chrome Web Store and open the uBlock Origin Lite page.
2. Select Get extension on the banner at the top of the page, or the Get button.
3. If Edge asks, select Allow extensions from other stores.
4. Review the permissions and select Add extension.
5. Confirm the extension appears under Extensions.

Configuring uBlock Origin Settings for Optimal Performance

uBlock Origin works the moment it installs. These settings control where it runs and which lists it uses.

1. Select Extensions, then … More actions next to uBlock Origin and hover over This can read and change site data.
2. Keep On all sites so it can block on every page, or choose When you click the extension to limit it.
3. Open Extensions > Manage extensions, then Details under uBlock Origin.
4. Under Site access, turn on Allow in InPrivate if you want blocking in InPrivate windows.
5. Leave Allow access to file URLs off unless you need it on local files.
6. Open uBlock Origin's own options page from Details to add filter lists such as EasyList Cookie or Fanboy Annoyances.

The default lists are EasyList, EasyPrivacy, Peter Lowe's Ad server list, the Online Malicious URL Blocklist and uBlock Origin's own lists. Adding many more lists rarely helps and uses more memory.

How to check uBlock Origin is working

1. Select Extensions and confirm uBlock Origin is listed.
2. Open Manage extensions and check its toggle is on.
3. Visit a site that normally shows ads and reload it.
4. Confirm the ad slots are now empty or gone, then open the same page in an InPrivate window to compare if you turned on Allow in InPrivate.

Troubleshooting Common Issues During Installation of uBlock Origin on Edge

The Get button does nothing or the install fails

Edge is out of date or the connection dropped mid-install. Ensure browser compatibility first.

1. Select Settings and more > Help and feedback > About Microsoft Edge and install any update.
2. Restart Edge.
3. Open the Edge Add-ons page again and select Get.

Chrome Web Store extensions will not install

Edge blocks other stores until you allow them, which is how extensions from outside the Microsoft store are enabled.

1. Select Get extension on the Chrome Web Store page.
2. Select Allow extensions from other stores when Edge asks.
3. Select Add extension.

Pages still show ads

A conflicting ad-blocking extension, or limited site permissions.

1. Open Extensions > Manage extensions and turn off other ad blockers to check for conflicting extensions.
2. Verify extension permissions: set This can read and change site data to On all sites.
3. Turn on Allow in InPrivate if the ads appear only in InPrivate windows.

uBlock Origin was turned off by itself

Edge turns off extensions that try to change default settings without permission, or shows a Manifest V2 warning.

1. Select Settings and more > Extensions > Manage extensions.
2. Find uBlock Origin and turn its toggle back on.
3. If Edge keeps showing a Manifest V2 deprecation warning, install uBlock Origin Lite.

You cannot install any extension on a work PC

Your organisation manages Edge and restricts extensions.

1. Check for a message that your browser is managed by your organisation.
2. Ask your IT administrator to allow the extension.

Updating and Managing uBlock Origin Extensions in Edge

Store extensions update along with their store listing, so checking for extension updates is rarely needed. These steps cover manual updates and removal.

1. Update Edge itself from Settings and more > Help and feedback > About Microsoft Edge.
2. To update uBlock Origin manually, remove it and add it again from Edge Add-ons, which installs the current listed version.
3. To pause it, open Extensions > Manage extensions and turn its toggle off.
4. To remove it, right-click the uBlock Origin icon and select Remove from Microsoft Edge > Remove.
5. To manage extension settings later, open Manage extensions and select Details.

Additional Tips for Enhancing Browser Security and Privacy

Tip	Reason
Install only the listing by Raymond Hill	Copycat blockers with similar names have been pulled from the Edge store, such as the fake uBlock Adblock Plus extension
Run one content blocker, not several	Overlapping blockers conflict and make pages harder to troubleshoot
Limit site access for other extensions	When you click the extension stops an add-on reading every page
Turn off extensions you no longer use	Each one can read site data you allowed it to
Keep Edge updated	Edge updates on restart unless a metered connection blocks it
