Whenever I watch videos on Firefox, I get an error that shows "A network caused the media download to fail part way." I need to use Firefox for my MA studies so I won't be able to change the browser anytime soon. I need someone to help me resolve this issue permanently. I will need to test your solution for 5 days. After 5 days, I will pay you super fast on Freelancer and leave feedback for you. Please see the attached image for your reference. Payment will be $20 USD for a permanent solution in Firefox.
