Cove Download Manager by Sin

Cove Download Manager integrates with Firefox to speed up downloads using aria2's multi-connection download engine. When enabled, supported downloads are automatically intercepted and sent to the Cove desktop application, where files can be split across multiple connections for faster download speeds.

Firefox Permissions & Privacy

Firefox may display a permission warning stating that Cove can "Access your data for all websites." This permission is required because Cove needs to recognize download links and supported media across the websites you visit.

Cove uses this access only for download-related features, including detecting downloadable links and media and passing the download URL, cookies, and referrer information to the local Cove Download Manager application when needed for a download.

Cove does not use this permission to collect passwords, form entries, messages, or other unrelated page content, and it does not track your browsing activity.

Features

• Automatically captures supported browser downloads and sends them to Cove when interception is enabled
• Right-click "Download with Cove" option for links, images, videos, and audio files
• Forwards cookies and referrer information when required for authenticated downloads
• Toggle automatic download interception on or off with Alt + Shift + D
• Toolbar popup displays Cove connection and interception status
• Configurable file type filters, size limits, and domain exclusions

In-page Video Downloads

Hover over an HTML5 video and a floating "Download with Cove" button appears in the corner of the player.

One click sends the detected video to Cove along with the page's cookies and referrer information when required. Direct MP4 and WebM sources are supported. On Firefox, Cove can also detect supported HLS (M3U8) streams.

Nothing downloads from the in-page video button without an explicit click, and DRM-protected media is never touched.

Requirements

• Cove Download Manager desktop application must be installed and running.
