Downloading Issue with SeaMonkey

I’m a nubie so excuse me if this is posted in the wrong area.
So I click download and my browser keeps throwing up blank pages - hundreds of them until the browser finally crashes.
Nothing downloads?
I tried this a couple of times with the “free” downloads you have.
I really don’t want to install another browser and try again… but I am wondering if this problem has occurred to any one else?
The actual Unreal Engine downloaded okay and I am able to play around with it ok but the content download error has made me wonder.

The content doesn’t download from the browser, it downloads through the Epic launcher. Where are you trying to download from?

the marketplace… but when I click download it just opens hundreds of blank browser windows. then crashes
I’m sure it’s my fault - it always is.
I’ll try again later.
