Prerequisites
Before you start, make sure you have the extension files ready on your computer.
DOWNLOAD THE FILES HERE
The extension comes as a .zip file, you must unzip (extract) it first.
You should have a folder that contains a file named
manifest.json.Tip: use a folder that you won't delete as the extension stops working if you move or delete this folder.
Step 1: Open the Extensions Page
Open Google Chrome.
In the address bar at the top, type
chrome://extensionsand press Enter.Alternative: Click the three dots icon (top right) $\rightarrow$ Extensions $\rightarrow$ Manage Extensions.
Step 2: Enable Developer Mode
Look at the top-right corner of the Extensions page.
Find the toggle switch labeled Developer mode.
Turn the toggle ON (it should turn blue).
Step 3: Load the Extension
Once Developer mode is active, three new buttons will appear at the top left of the page.
Click the button labeled Load unpacked.
A file selection window will pop up. Navigate to the folder where you saved your extension files.
Crucial: Select the folder (directory) that contains the
manifest.jsonfile. Do not open the folder to select individual files; just highlight the folder itself.Click Select Folder (or "Open" on Mac).
Step 4: Verify Installation
The extension should now appear in your list of installed extensions. You should see its icon, name, and version number.
Important Note: Chrome runs the extension directly from the folder on your computer. Do not delete or move that folder, or the extension will stop working.
