If you abruptly begin seeing adverts once more and see that uBlock Origin is turned off in Chrome, it normally means Chrome has marked it as “no longer supported” and disabled it mechanically.

In most instances, this occurs as a result of Chrome is retiring Manifest V2 (MV2) extensions and transferring to Manifest V3 (MV3). The full uBlock Origin depends on MV2 options, so newer Chrome builds could disable it (and should not allow you to re-enable it completely).

uBlock Origin Lite (Chrome Web Store). - Click Add to Chrome to put in it.

- Go to chrome://extensions/ and ensure uBlock Origin Lite is enabled.

For most customers it nonetheless works nice, however some websites (particularly with aggressive anti-adblock) could also be harder.

- Download and set up Firefox:
Download Firefox. - Open Firefox, go to the add-ons retailer, and seek for uBlock Origin.
- Install it and maintain it enabled from the extensions/add-ons menu.
3 Manually Install uBlock Origin From the Official GitHub Release
If the Web Store model is unavailable/disabled, you’ll be able to strive putting in the official Chromium construct as an unpacked extension. It gained’t auto-update, and it might nonetheless cease working in case your Chrome construct removes MV2 fully.
Step 1: Download and Extract
- Open the official uBlock Origin releases web page:
uBlock Origin (GitHub Releases). - Download the Chromium zip from the most recent launch (normally uBlock0_
.chromium.zip ). Do not obtain “Source code (zip)”. - Extract the zip to a folder you’ll maintain completely.
Step 2: Load Unpacked
- In Chrome, go to chrome://extensions/.

- Enable Developer mode.

- Click Load unpacked.
