User reviews

Users find Free Download Manager useful for managing downloads but frequently complain about mandatory anonymous data collection, which raises privacy issues. It struggles with compatibility on newer Firefox versions and Windows 11, inconsistent download capture, and high CPU usage. These issues diminish user trust despite the add-on's functional benefits in handling downloads.
Pros
  • Good download manager recommended by users.
  • Effective in managing larger downloads.
  • Has a user base that considers it the best download manager.
  • Offers multiple options to configure download capture.
Cons
  • Forces users to accept anonymous data collection to install, leading to privacy concerns.
  • Does not work properly on the latest Firefox versions and Windows 11.
  • Fails to capture all downloads reliably, especially smaller files or some large files.
  • High CPU usage reported during operation.
  • Lacks transparency and causes distrust regarding data collection and privacy practices.
Recent reviews
1 Star, because if you don't accept the anonymous data collection it won't install. Removed and reported.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Free Download Manager official extension requires a lot of sensitive permissions. Exercise caution before installing.

Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
