Chrome & Chromium Installation

The Fetchii extension for Chrome adds a right-click menu to download videos directly from your browser. When you choose to download, it sends the URL along with your login cookies to Fetchii, enabling access to private and restricted content. The recommended way to install it is from the Chrome Web Store — one click, and it updates itself. If the Web Store isn't available to you, you can still load the copy bundled with Fetchii using Developer Mode.

This guide works for Google Chrome, Brave, Microsoft Edge, and Chromium — the Chromium-based browsers Fetchii lists under Supported Browsers.

Starting the Setup

Fetchii walks you through the installation:

Open Fetchii
Choose Help > Set up browser extension (or open Settings > Browser Extension)
Under Supported Browsers, find your browser and click Install

A setup sheet opens for that browser. Its first page offers two ways to install.

Installing from the Web Store (Recommended)

The highlighted card, Add to Chrome from Web Store, installs in one click and updates automatically:

Click Open Web Store. The extension's store page opens in the browser you picked.
Click the browser's add button and confirm.
Back in Fetchii, click I've Installed It.

Verify the Setup

The last page shows a short checklist — Browser detected, Browser extension installed, and Connection to Fetchii verified — and checks the connection right away. If a step hasn't passed yet, the page tells you what to do; fix it and click Verify Setup to check again. Once every step is ticked, the page says Extension Ready and you can click Done.

Installing Offline (Advanced)

Use this only if the Web Store isn't available. Expand Install offline (advanced) on the setup sheet. It shows the path of the extension folder bundled with Fetchii, with a copy button. The folder lives at:

/Applications/Fetchii.app/Contents/Resources/BrowserExtension/

Enable Developer Mode

Click Open Chrome Extensions on the sheet (it names the browser you picked), or type the address yourself:

Chrome and Chromium: chrome://extensions
Brave: brave://extensions
Edge: edge://extensions

Look for the Developer mode toggle (usually in the top-right corner) and turn it on.

Load the Extension

With Developer Mode enabled, you'll see a new "Load unpacked" button. Click it, press ⌘⇧G to open the path dialog, paste the folder path, and select the folder. The extension should appear in your list immediately. Then click I've Installed It in Fetchii and verify the setup as described above.

Pin It for Easy Access

The extension might be hidden in your extensions menu (the puzzle piece icon). Click that icon, find Fetchii, and click the pin to keep it visible in your toolbar.

How to Download

Once installed, the extension adds a right-click context menu to download videos directly from your browser.

To download videos:

Make sure you're logged into the video site in your browser
Right-click on a video, link, or page
Select "Download with Fetchii" from the context menu
The extension sends the URL and your cookies to Fetchii for downloading

With your login cookies included, you can download private videos, age-restricted content, and subscription-only material — as long as you're logged into the site in your browser.

Things to Know

Developer Mode Warnings

If you used the offline install, your browser might occasionally show warnings about running extensions in Developer Mode. This is normal and expected — it's just reminding you that the extension wasn't installed from the Chrome Web Store. Click "Keep" or dismiss these warnings. The Web Store version doesn't trigger them.

Extensions After Browser Updates

Chromium browsers sometimes disable unpacked extensions after updates. If your extension stops working:

Open the extensions page
Find Fetchii (it might show "Errors")
Toggle it back on, or click "Load unpacked" again if needed

Keeping in Sync with Fetchii Updates

The Web Store version updates automatically. If you loaded the extension offline, reload it from the same folder after Fetchii updates to pick up the new version.

Troubleshooting

Extension won't load: Make sure you're selecting the folder itself, not a file inside it. The folder should contain a manifest.json file.

Downloads don't reach Fetchii: Make sure Fetchii is running — the extension needs the main app to process downloads. Then open Settings > Browser Extension and click Test Connection; your browser's row under Supported Browsers shows the result.

Different extension ID: If Chrome assigns a new ID (which happens sometimes with the offline install), remove the old extension and load it fresh. You'll need to re-pin it to the toolbar.

Security Note

The Developer Mode warning in the offline install might seem concerning, but the Fetchii extension is completely safe. It only does two things: adds a right-click download menu and sends your cookies to the local Fetchii app when you choose to download. Cookies are never accessed automatically — only when you explicitly request a download. No data is ever sent anywhere else.
