• Clear Firefox downloads history or change the downloads folder if you can’t download any specific files.
  • Remove any recently added extensions from your Firefox browser and check again.
  • You can also use the Firefox Refresh feature to delete all custom browser settings and try downloading the file again.

Basic Fixes:

  • Pause and resume the download: After restarting a failed download, it can get stuck and fail again. To fix this, try pausing and resuming the download.
  • Check your network connection: Downloads need a stable Wi-Fi connection to work. If you’re facing problems related to downloads on Firefox, it is recommended that you check your Wi-Fi services and ensure you’re connected to a stable network.
  • Disable VPN: VPN services can also cause problems with downloads, as they might limit data speeds and even restrict certain websites due to changes in your geolocation. To fix that, go to your VPN app and click on the Disconnect button.
  • Clear Firefox cookies and cache: Every browser saves information to load the web page faster and ensure a smooth experience. However, this data can also cause problems if it becomes compromised. When this happens, clear Firefox’s cache and cookies.
  • Check for browser updates: Keeping your browsers up-to-date has become a necessity. If your browser faces issues like download failures, it might be a good idea to check and install the latest browser updates.
  • Reinstall Firefox: If your downloads are still failing, reinstalling Firefox can be your last resort to fixing it. This will not only eliminate any errant custom settings but also clear problems caused by a bad update or data error.
