Browser & downloads

The current source includes Chrome/Chromium and Firefox browser companions. Follow the extension setup in Duvrin and check your installed release for its browser support. Chrome is set up by loading a prepared local extension folder; Firefox uses the signed extension file included with the release.

Duvrin manages everyday file links, installers, archives, documents, images, and supported video or audio media. Availability depends on the source. DRM-protected, sign-in-gated, and age-restricted media are not supported; Torrent, FTP, and Metalink are outside the first-release scope. Only download content you own or have permission to save.

Browser requests go through Duvrin’s native confirmation workflow. Review the filename and destination before starting. An explicit, saved “Skip this dialog” preference can use your chosen defaults for future eligible requests; websites do not gain permission to administer the app. Leave “Start browser downloads immediately” off while you are learning your way around.

Yes. Duvrin retains transfer progress for supported resumable sources, and pausing keeps the bytes it already received. If the source no longer offers the same file or stops accepting resume requests, Duvrin reports the problem rather than silently replacing an existing partial with different content. Never delete the item or its partial files as a way to “fix” a resume.

Usually the app is closed, or the companion is switched off in the browser profile you are using. Open Duvrin from Applications and leave it running, open Settings → Extensions and finish any setup or update step, then reopen the companion and reload the page. The popup describes the connection to the app on your Mac, so it is not by itself evidence that a licensing website is down.

That is how Chrome shows an extension that is switched off. Click the Duvrin icon on your toolbar to switch it back on. Two details catch people out: the icon can be toggled for the current tab only, so other open tabs keep their own state, and in Chrome the icon must be pinned from the extensions menu before it appears on the toolbar at all.

Each browser profile has its own extensions. Installing the companion in your everyday Chrome profile does not install it in a second profile, an incognito window, or another browser entirely. Run the setup guide again from inside the window where nothing is being caught, and check the browser name and profile in that window.

In Chrome, the companion is loaded as an unpacked folder rather than installed from the store, so it will not appear until you complete the guided setup. Open Settings → Extensions in Duvrin, choose Set Up Browser…, and follow the guide for your browser. Turning on Developer mode and choosing Load unpacked with the folder the guide points at is the whole installation.

Right-click a link and you should see “Download this link with Duvrin”; right-click anywhere on a page for “Download this page with Duvrin”. These items appear once the companion is installed and enabled, and the page itself must be finished loading. The link item needs a genuine file or media address; a link to an HTML page is not a download.

Yes, and it is worth remembering for sites that need your browser to handle a file themselves. Click the companion icon to switch it off for the current tab, then let the browser save the file as it normally would. For a site you visit often, the simplest durable answer is to keep the companion off there and use the browser’s own download button.

Open Add Download in Duvrin, paste the direct file address into Source URL, and choose Inspect to review the detected details. Confirm Save as and Destination, then choose Start. Use this for anything you already have the address for. A link to a web page is not always a link to the file itself.
