Unseen

Install Unseen

Chrome and Edge

The Chromium download is an unpacked extension for local installation.

  1. Download the extension ZIP and extract it to a folder you will keep.
  2. Open chrome://extensions in Chrome or edge://extensions in Edge.
  3. Enable Developer mode, choose Load unpacked, and select the extracted folder containing manifest.json.
  4. Reload any open supported pages. Use Unseen’s toolbar menu to pause filtering or open Settings.

Firefox candidate

The Firefox build is a testing candidate. It can be installed temporarily for evaluation; it is not a signed Mozilla Add-ons release.

  1. Download the Firefox candidate ZIP.
  2. Open about:debugging in Firefox and choose This Firefox.
  3. Choose Load Temporary Add-on and select the Firefox ZIP, or extract it and select manifest.json.
  4. Reload supported pages to try the extension. Temporary installation ends when Firefox restarts.

See Mozilla’s temporary-installation instructions. Export a backup before removing or replacing a candidate.

Supported pages

Desktop YouTube and Pornhub standard video detail pages and recognized feed cards. Supported hosts: www.youtube.com, www.pornhub.com and jp.pornhub.com.

YouTube Shorts playback and feed cards are supported. Live streams, embedded players, other regional hosts and private browsing are not supported. Unseen starts recording playback after installation; it cannot recover your earlier account history.

Read the YouTube guide or Pornhub guide for site-specific controls.

Updating or removing

For a Chromium local install, keep the extension folder at the same location. Replace its files with the new version, then use Reload in the extensions page and reload video tabs. Export a backup before reinstalling or changing the installation directory.

To remove Unseen, choose Remove on the extensions page. Downloaded backups are separate files and remain until you delete them. See help and support for troubleshooting and backup guidance.
