Install the Astral Chrome extension

Download from Astral

Use Astral's Extension page for the current archive and guide. Do not install a repackaged copy from an unrelated download site.

Load the unpacked folder

1. Extract the downloaded ZIP to a permanent folder.
2. Open chrome://extensions.
3. Enable Developer mode.
4. Choose Load unpacked and select the extracted folder.

Keep the folder

Note: Chrome loads the extension from that folder. Moving or deleting it breaks the installed unpacked extension.
