Generate Archive fails

I generally use the Vivaldi browser (uses the chrome core) and when hitting the "Generate archive" button in the System->"Backup / Flash Firmware" section on Luci, it does nothing. If I open the same page in Chrome, I get a pop-up message stating that an insecure download was blocked and allows me to click on the "Keep" button to save the download. And, Firefox downloads the file.
What settings do I need to change in OpenWRT that allow the archive to be downloaded securely and avoid having to jump through hoops to get the archive?


Ain't it some setting in your browser?
I am using Brave (also build on chrome) and Firefox without any problems.

You arr not the only one having these issues using Vivaldi:
