User reviews

Users report that while the add-on attempts to integrate with Free Download Manager, it often fails to capture many downloads reliably across platforms and browsers. There are significant issues on newer operating systems and packaged environments. Additionally, the requirement to accept anonymous data collection to use the add-on raises privacy worries among users, further detracting from its usability and trustworthiness.
Pros
  • Offers integration to manage downloads via Free Download Manager
  • Provides options to adjust download capture settings
  • Works in conventional installations on some platforms
Cons
  • Frequently fails to capture all downloads; captures only about 50% or less
  • Does not work or integrate properly on newer systems like Windows 11, Mac, flatpak, or some Firefox versions
  • Forces users to accept anonymous data collection to use the add-on, which raises privacy concerns
  • Fails to capture downloads under 1MB despite settings changes
  • Lacks automation for some downloads, requiring manual input or fails to acknowledge download attempts

The CPU usage for this addon is crazy. MTFK 10~20%!!! Are you mining or something?

Cannot capture downloads of files smaller than 1MB, even if I haven't turned on the option 'Don't catch downloads smaller than Mbytes'
