Browser Extensions Overview

The Fetchii browser extension, Fetchii Browser Helper, adds a convenient right-click menu to download videos directly from your browser. When you choose to download, the extension sends the URL along with your login cookies for that site to Fetchii, enabling access to private and restricted content.

Supported Browsers

Fetchii works with Safari and the main Chromium browsers on macOS. Safari's extension comes bundled with the app, while Chrome, Brave, Edge and Chromium install it from the Chrome Web Store. You'll find every supported browser in Fetchii → Settings → Browser Extension, with an Install button next to each one you have.

Browser	Setup	Notes
Safari	Built-in	Bundled with Fetchii — enable in Safari settings
Google Chrome	Chrome Web Store	Installs in one click and updates automatically
Brave	Chrome Web Store	Same process as Chrome
Microsoft Edge	Chrome Web Store	Same process as Chrome
Chromium	Chrome Web Store	Same process as Chrome

What the Extension Does

The browser extension serves one key purpose: right-click downloads with authentication.

When you're logged into websites like YouTube, Vimeo, or X, your browser stores cookies that prove your identity. When you right-click on a video and choose Download with Fetchii, the extension sends both the URL and your cookies for that site to the app, allowing authenticated downloads. On a live stream, the menu item reads Record with Fetchii.

How it works:

You log into a video site in your browser
Right-click a video, link or page and select Download with Fetchii — or click the Fetchii icon in the toolbar and choose Send this page to Fetchii
The extension sends the URL and your cookies to Fetchii
Fetchii uses your cookies to access and download the content, at your default quality from Settings → Downloads

The toolbar popup also tells you whether the extension can reach Fetchii. If it says "Fetchii isn't open", open the app and try again.

Quick Setup Guides

Safari

Safari's extension is the easiest to set up since it's bundled with Fetchii:

In Fetchii, open Settings → Browser Extension and click Install next to Safari — or open Safari → Settings (Cmd + ,) yourself
Click the Extensions tab
Find Fetchii in the list and check the box to enable it
Click the Fetchii icon in Safari's toolbar and choose Always Allow on Every Website — without this, downloads and login passing won't work

That's it! Check out the full Safari guide if you run into issues.

Chrome, Brave, Edge and Chromium

For Chrome and the other Chromium browsers, Fetchii takes you to the Chrome Web Store:

In Fetchii, open Settings → Browser Extension and click Install next to your browser
Click Add to Chrome from Web Store — the Fetchii Browser Helper page opens in that browser
Add the extension, then pin it to your toolbar for easy access

The process takes about a minute. If the Web Store isn't available, Install offline (advanced) loads the extension from a folder bundled with the app instead. See the detailed Chrome/Chromium guide for step-by-step instructions.

What You Can Access

With cookies synced from your browser, Fetchii can download:

Private videos — Videos you've set to "private" on your own channel
Unlisted videos — Videos shared via direct link
Age-restricted content — Videos that require login verification
Channel member exclusives — Membership-only videos
Subscription content — Videos from paid services you subscribe to

Cookies are only sent when you explicitly choose to download — just make sure you're logged into the site before right-clicking to download. Fetchii keeps them on your Mac for 7 days by default; you can change this in Settings → Browser Extension → Cookies from Browser Extension → Cookie retention.
