Extensions

Orbit runs Chrome extensions. They show as icons next to the address bar, and clicking one opens its pop-up, as in Chrome. Manage them in Settings → Extensions.

Add one from the Chrome Web Store

Open an extension's page on the Chrome Web Store. A bar appears under the toolbar; choose Add to Orbit. (The store's own "Add to Chrome" button doesn't work in Orbit.) Reload open pages afterwards.

Install uBlock Origin

Settings → Extensions → Install next to uBlock Origin downloads the latest release from its GitHub page and loads it.

Add one from a folder or zip

  • Add from folder… takes an unpacked extension: a folder that contains manifest.json.
  • Add from .zip… takes a zip of such a folder.

Orbit keeps extensions in %APPDATA%\Orbit\extensions and loads them every time it starts.

Using and removing them

  • Click an icon to open the extension's pop-up. Extensions without a pop-up run their own click action on the page you're looking at.
  • Right-click an icon for Options, Manage extensions and Remove from Orbit.

Updates

Extensions from the Chrome Web Store and uBlock Origin are checked for newer versions about once a day (or press Check for updates in Settings → Extensions). A new version is downloaded in the background and takes over the next time Orbit starts. Their settings and saved data are kept. Extensions you add from a folder or zip are never updated automatically: add the newer version again yourself.

Limits

  • Manifest V2 and V3 extensions both load, with their background scripts, content scripts and request blocking.
  • Extensions don't work in private windows. WebView2 keeps private tabs hidden from them, so Orbit leaves their icons out of private windows.
  • An extension that relies on the activeTab permission may be unable to act when you click its button, because Orbit can't grant that permission the way a real browser does.
  • Extensions can read and change the pages you visit. Only add ones you trust.

Why Orbit is built this way

Orbit uses Microsoft's WebView2 engine, which is the Chromium-based engine of Edge, with extension support built in but without the browser's own extension interface. Orbit adds the install, toolbar, pop-up and update parts itself.
