  • Latest version

    Version 1.4.1

    Released Jul 17, 2026 - 68.81 KB
    Works with firefox 140.0 and later, android 142.0 and later
    What's new in 1.4.1:
    • Fixed: clearing the minimum file size field in the options page no longer silently disables the size filter. An empty field is now treated as 0 (intercept
      all sizes).
    • Fixed: file sizes of 1 TB and above now display correctly in the popup instead of showing "undefined".
    • Fixed: the popup no longer logs repeated errors while the extension's background process is restarting.
    • Improved: responses from the Cove desktop app are now validated more strictly, so a malformed reply can no longer leave a download in a stuck state.

    Requires the Cove Download Manager desktop app. Version 2.0.1 of the app is recommended, as it includes matching reliability fixes for browser-initiated
    downloads.

  • Version 1.3.0

    Released Jul 4, 2026 - 62.46 KB
    Works with firefox 91.0 and later
    New in 1.3.0: in-page video download pill.
    • Hover any HTML5 video and a floating "Download with Cove" button appears in the top-right corner of the player. One click sends the video to the Cove
      desktop app with the page's cookies and referrer.
    • Supports direct MP4/WebM video sources, plus HLS (M3U8) streams the extension has detected for the tab (useful for players that use blob/MSE sources).
    • Nothing downloads automatically: the pill only acts on an explicit click, shows a "Sent to Cove" state to prevent duplicates, and never appears for
      DRM-protected media.

    Existing features (download interception, right-click "Download with Cove", detected stream list, Alt+Shift+D toggle) are unchanged.
