How to install

Installing a ufahelp extension in Chrome.

Our extensions aren't in the Chrome Web Store (the review process isn't kind to small free tools). Installing them takes about a minute — you turn on a setting called Developer Mode, then point Chrome at the folder you downloaded.

Steps

Once per extension

Download the .zip

From the home page, click Download next to the extension you want. A .zip file lands in your Downloads folder.

Unzip it

On Mac, double-click the .zip. On Windows, right-click and choose Extract All. You'll get a folder with the same name.

Move the folder somewhere safe

Drag the unzipped folder into your Documents folder (or anywhere you won't accidentally delete it). Chrome runs the extension from this folder every time — if you move or delete it, the extension stops working.

Open chrome://extensions

Paste chrome://extensions into Chrome's address bar and press Enter.

Turn on Developer mode

Look in the top-right corner of the extensions page. Flip the Developer mode toggle on. A new row of buttons appears.

Click Load unpacked

The button is on the top-left. A folder picker opens.

Select the unzipped folder

Pick the folder you moved in step 3 — the one containing a manifest.json file. Click Select.

Pin the icon (optional but nice)

Click the puzzle-piece icon in Chrome's toolbar. Find the extension you just installed and click the pin next to its name. It'll sit in your toolbar from now on.

Updating

When a new version drops

Re-download the .zip from the home page.
Unzip it and replace your old folder's contents with the new ones (or just delete the old folder and unzip in place).
Go to chrome://extensions and click the ↻ refresh button on the extension's card.

Troubleshooting

If something doesn't work

The extension's icon never showed up.

Double-check that Developer mode is still toggled on in the top right of chrome://extensions. If Chrome restarted, it stays on — but if you turned it off, every loaded extension goes dormant.

Chrome says “Manifest file is missing or unreadable.”

You probably selected a wrapping folder. Open the folder Chrome rejected — if you see a single inner folder with the extension's name, select that inner folder instead. The folder you pick must contain manifest.json directly.

The extension suddenly stopped working.

The unzipped folder probably got moved, renamed, or deleted. Find or re-download it and re-run Load unpacked.

I use Edge or Brave, not Chrome.

Same steps work — just open edge://extensions or brave://extensions instead. Firefox is different and these extensions won't install there.

Is this safe? Why all the warnings?

Chrome shows a yellow banner saying “disable developer mode extensions” — that's a generic warning for anything not from the Chrome Web Store. The source code for every extension is open and the only place it talks to is the site it's built for (Amazon, Odyssey, or ufahelp). You can remove an extension any time from chrome://extensions.
