Thanks for your tests.With SmartScreen enabled Edge Download protection (9/16) warned/blocked all VX Vault and URLhaus downloads.
Without SmartScreen Windows Defender (9/16) blocked all VX Vault and URLhaus downloads.
So there is definitely something wrong with the latest version of Bitdefender TrafficLight on the latest Edge Dev!
Edge Dev with SmartScreen should be enough in this test and the only option for me now could be Malwarebytes Browser Guard.
Disclaimer: too small a set of links to take this test seriously. Just an indication.
