How to Install uBlock Origin on Chrome Manually
How to install uBlock Origin on Chrome in 2026 is still possible if you manually load the extension from the official release files. This guide shows one fix: downloading the Chromium ZIP, loading uBlock Origin as an unpacked Chrome extension, and launching Chrome with the correct Manifest V2 shortcut flag.
Google has been moving Chrome extensions toward Manifest V3, which can cause the full uBlock Origin extension to stop working, become disabled, or show a message that it is no longer supported. Google's own extension documentation confirms Manifest V2 extensions are now disabled in Chrome and flagged as no longer supported (Manifest V2 support timeline). The steps below are for people who still want to use the full uBlock Origin extension on Chrome instead of only relying on the Chrome Web Store.
Before you start, close every Chrome window. This is important because Chrome needs to restart after the policy command and shortcut flag are added.
Step 1: Add the Chrome policy command
Open a Command Prompt window as an administrator. You can do this by searching for Command Prompt, right-clicking it, and selecting Run as administrator.
Paste the following command into the administrator Command Prompt window:
reg add “HKLM\SOFTWARE\Policies\GoogleChrome” /v ExtensionManifestV2Availability /t REG_DWORD /d 1 /f
If the command runs successfully, Windows should show a confirmation message. This command adds a Chrome policy that helps with the uBlock Origin Manifest V2 setup.
If you pasted it correctly, it will look similar to this:
Step 2: Download uBlock Origin from GitHub
Close the Command Prompt window and go to the official uBlock Origin GitHub releases page.
On the GitHub page, find the Releases section. The page may show the latest release automatically, or you may need to click into the releases page to see all downloadable files.
In the latest release, scroll down until you find the file named CHROMIUM.zip. Click it to download the Chromium version of uBlock Origin for Chrome. uBlock Origin's own install notes direct users to this Chromium package from the GitHub releases page (uBlock Origin install instructions).
This will download uBlock Origin as a ZIP file. Locate the downloaded ZIP file on your computer before moving to the next step.
Step 3: Extract the ZIP file
Right-click the downloaded ZIP file and extract it. If you use WinRAR, you can select WinRAR → Extract to…. You can also use the built-in Windows extract option.
Do not try to load the ZIP file directly inside Chrome. Chrome needs the extracted folder, not the compressed ZIP file.
Step 4: Load uBlock Origin as an unpacked extension
Open Chrome and go to:
chrome://extensionsTurn on Developer mode if it is not already enabled. Then click the Load unpacked button near the top of the page.
File Explorer will open. Locate the folder you extracted from the ZIP file. In this example, the folder is inside the Downloads folder.
Click the extracted uBlock Origin folder once, then click Select Folder in the bottom-right corner.
You should now see uBlock Origin listed on the Chrome extensions page. This Developer mode plus Load unpacked flow is exactly how Google documents installing an unpacked extension (Load an unpacked extension).
Step 5: Create the Chrome shortcut fix
Now you need to close Chrome and create a shortcut with a specific parameter added to the Target field.
Click the Windows search bar and type Chrome. Right-click Google Chrome and select Open file location.
This will take you to a folder where Windows stores shortcuts. Locate the Google Chrome shortcut.
Right-click the Chrome shortcut and select Properties.
Now focus on the Target field. Copy the following text:
–disable-features=ExtensionManifestV2Unsupported,ExtensionManifestV2Disabled
Click inside the Target field, move your cursor all the way to the end of the line, press Space once, and then paste the text above.
If Chrome was installed in the default location, your updated Target field should look like this:
C:Program Files\Google\Chrome\Application\chrome.exe” –disable-features=ExtensionManifestV2Unsupported,ExtensionManifestV2Disabled
Click Apply, then click OK. From now on, you should launch Chrome from this edited shortcut so the setting is applied every time.
You can move the shortcut to your desktop by dragging it from the folder to your desktop.
Step 6: Turn uBlock Origin on in Chrome
Launch Chrome using the edited shortcut and go back to:
chrome://extensionsYou should see uBlock Origin listed there. If it is turned off, toggle it on.

Frequently asked questions
Why did uBlock Origin stop working on Chrome?
Google is moving Chrome extensions to Manifest V3, which can disable the full uBlock Origin extension or mark it unsupported. The full version relies on Manifest V2, so it needs a policy flag and a manual install to keep running.
Can I still install the full uBlock Origin in 2026?
Yes. Add the ExtensionManifestV2Availability Chrome policy via an admin Command Prompt, download the official Chromium ZIP from the uBlock Origin GitHub releases page, load it as an unpacked extension, and launch Chrome with the correct shortcut flag.
Where should I download uBlock Origin from?
Only from the official uBlock Origin GitHub releases page. Third-party mirrors of extension files are a malware risk, and the GitHub release is the version the manual install steps in this guide are built around.
