Chrome saves it in your Downloads folder.

- Open your Downloads folder. (Press the Windows key and E together, then click Downloads.)
- Right-click “defend-hq-extension-5.7.1-chrome.zip” and choose Extract All…
- Click Extract. A folder called “defend-hq-extension-5.7.1-chrome” opens.
Keep this folder. Chrome uses it every time it starts. A good home for it is your Documents folder. Move it there now, before the next step.
Open Chrome’s extensions page
Click the address bar at the top of Chrome, type this, and press Enter:
chrome://extensionsThen turn on Developer mode, with the switch in the top-right corner of that page.
Websites can’t open this page for you. That’s one of Chrome’s safety rules.Choose the Defend HQ folder
Click Load unpacked, at the top left. Choose the “defend-hq-extension-5.7.1-chrome” folder, then click Select Folder (Windows), Select (Mac) or Open (Chromebook).
Defend HQ appears in the list, with the green shield.
If Chrome says the manifest file is missing, a different folder was chosen. Choose the one with a file called manifest.json inside.Follow the welcome page
Defend HQ opens its welcome page by itself: who it’s for, pinning the green shield, choosing your trusted person, and what it looks after. Then you’re ready.
After that, just browse as usual. Defend HQ steps in when something needs a second look.
