User Reviews

NAS Download Manager is highly appreciated for its seamless integration with Synology NAS, saving users time and simplifying downloads. However, it requires HTTPS connections which cause issues on local networks without proper certificates. Users face occasional loss of saved settings and challenges with magnet link support. Additionally, 2FA causes compatibility problems, and development seems to have slowed or stopped, leaving some bugs unaddressed.

Pros

Works well with DSM 7.1.1 and earlier versions like DSM 6.2.4, providing seamless integration with Synology NAS.
Saves users time by simplifying downloads directly to their NAS, reducing the need for multiple clicks.
User-friendly and useful, regarded as one of the most helpful Firefox add-ons for Synology users.
Provides functionality to handle magnet links (with some workarounds).
Active community providing tips and fixes, like commands to bypass certain connection issues.

Cons

Requires HTTPS connection to the NAS, which is problematic for users with local or self-signed certificates, causing connection issues.
Occasional loss of saved NAS settings, forcing users to re-enter connection information randomly.
Magnet link support is buggy or broken since version 0.12.0, requiring debugging.
Two-factor authentication (2FA) compatibility issues, making the add-on unusable unless 2FA is disabled for users.
Development appears stalled, with bugs remaining unfixed and some users describing the project as abandoned.
