jet's interesting finds

1. Enable Legacy Extension Support
    Open Chrome and go to:
    chrome://flags
    In the search bar at the top of that page, type: Allow legacy extension manifest versions
    When it appears, set it to Enabled.
    Click the Relaunch button in the bottom right to restart Chrome.

2. Download uBlock Origin (Safe & Official Source)
    Go to the GitHub release page: 👉 https://github.com/gorhill/uBlock/releases
    Find the latest version at the top.
    Under Assets, download:
    uBlock0.chromium.zip

3. Extract the ZIP File

    On Windows: Right-click the file and choose "Extract All"
    On macOS: Double-click the zip to extract it

This will create a folder with all the uBlock extension files inside.

4. Load the Extension Manually in Chrome
    Open Chrome and go to:
    chrome://extensions
    Toggle Developer Mode ON (top-right corner).
    Click the "Load unpacked" button (top-left).
    In the file picker window, select the folder you just extracted from the zip file (not the zip itself).

I had to delete the old ublock origin extension, and load the downloaded version, the flag didn't work in place.

But it does work for me.
