Downloads are slow and need confirmation every time

Hello! I have been using Brave for some time now and I have noticed that everytime I download something on my IMac computer (such as a Picrew, a image, or custom content for the sims 4. Really anything.) using brave, my separate YouTube window (also on brave) turns black or slows, it needs confirmation to download every-time (which takes so much time), and it overall is quite annoying to download anything at all. If I could solve this issue on my own please let me know! -Sincerely Frank Tyler
