Use browser extensions

Choose an official listing below, then follow the guide for that browser. A listing marked as coming soon is not available yet; use Add URL in the desktop app until an official extension is published.

Install a source ZIP manually

For Chrome, Edge, Opera, or Brave, download that browser’s source ZIP, extract it to a permanent folder, open the browser’s extensions page, enable Developer mode, and choose Load unpacked. Select the extracted folder that contains manifest.json. Keep that folder in place while the extension is installed.

For Firefox, extract the Firefox source ZIP, open about:debugging#/runtime/this-firefox, choose Load Temporary Add-on, and select manifest.json. A source ZIP loaded this way is temporary and must be loaded again after Firefox restarts; permanent Firefox installation requires a signed add-on package.

Google Chrome

1. Install FID from the Chrome Web Store link above.
2. Open chrome://extensions and confirm the extension is enabled.
3. Open the extension and choose Connect / open FID.
4. Allow Chrome to open FID, approve the connection in the desktop app, then confirm the popup shows Desktop connected.

Microsoft Edge

1. Install FID from the Microsoft Edge Add-ons link above.
2. Open edge://extensions and confirm the extension is enabled.
3. Choose Connect / open FID in the extension.
4. Allow Edge to open FID and approve the connection. If pairing is unavailable in your release, use Add URL until Edge desktop integration is supplied.

Mozilla Firefox

1. Install FID from the Firefox Browser Add-ons link above.
2. Open about:addons, select Extensions, and confirm FID is enabled.
3. Open the extension and follow its connection prompt.
4. Approve the connection in FID when prompted. Firefox support requires a compatible FID extension and desktop release; a Chrome extension package cannot be installed as a substitute.

Opera

1. Install FID from the Opera Add-ons link above.
2. Open opera://extensions and confirm FID is enabled.
3. Choose Connect / open FID and approve the desktop connection.
4. If the listing or pairing option is unavailable, keep downloads in Opera or paste a direct link into FID.

Brave

1. Use the Brave-compatible official listing above.
2. Open brave://extensions and confirm FID is enabled.
3. Open the extension, choose Connect / open FID, and approve the connection.
4. Brave can use Chromium extensions, but desktop pairing still depends on the FID release supporting Brave.

Capture downloads and choose videos

Turn on Capture browser downloads to review supported browser downloads in FID. Capture is optional; leave it off for a download that must finish inside the browser, including form-based or browser-only transfers. If handoff fails, check the browser’s own downloads list.

Use the popup or a link’s context menu to send a URL to FID. Enable Show download buttons on videos for supported players. Browser-restricted pages, protected players, closed components, and some fullscreen layouts may not allow an in-page button.

Preferences and troubleshooting

Browser preferences can take up to a minute to sync while the browser is running. If the popup says disconnected, confirm the extension is enabled, browser integration is enabled in FID, and the browser-specific pairing step completed. You can always paste a direct file URL into the desktop app.
