Browser extension

The Manifest V3 extension supports current Chrome and Edge on Windows. It sends saves to the Stowspace Windows background service through the browser’s native-messaging bridge.

Install

Install from the store link on the download page when one is available. If the download page provides a ZIP instead:

1. Extract the ZIP to a folder you will keep.
2. Open chrome://extensions in Chrome or edge://extensions in Edge.
3. Turn on Developer mode.
4. Choose Load unpacked and select the extracted extension folder.

Install the Windows desktop app first. Its installer registers the native bridge that Chrome and Edge use.

Save from a page

• Open the extension popup to save the current readable page and optionally choose tags or collections.
• Use the page context menu to save page contents.
• Select text, right-click it, and choose the Stowspace action to save a snippet.
• Supported video pages are saved as video items.

When desktop is unavailable

If the extension cannot reach the background service, it stores the capture in a bounded local extension queue. It retries in the background and also lets you retry from the popup. Keep the extension installed and start Stowspace or its background service so the queued saves can finish.

The queue is a short bridge-outage safety net, not a cloud archive. If it fills, open Stowspace and retry before making more saves.

Extension cannot reach desktop

Confirm that Stowspace is installed, then start the desktop app once. In desktop settings, check the extension bridge status. If the connection still fails, reinstalling the desktop app restores the Chrome and Edge native-messaging registration.
