Hi,

I'm sorry to hear that. Does your Antivirus software has firewall installed? If it has, please check your firewall settings. It might blocking/Restrict Mozilla from connecting to the internet.

Please let me know if this helps.

Thank you!

It is possible that anti-virus software is corrupting downloaded files or is interfering otherwise.

Try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.

Open the options on all your protection and service programs, and tell them to leave the browsers alone.
