..... is a huge security risk.
Using Edge is a really bad idea from a security perspective; I would bet its protections turn out to be inadequate - even for a Windows App. Right now, it just can't be trusted .....
It has been a while since I was last logged in here, so was quickly looking though a few posts here and there and this caught my attention.
Considering that Appcontainer in Windows 10 in which Edge are running, are highly restricted in system access and very well isolated, I must say I find your statement intriguing.
In order for anyone to make such statement as yours, you would have had to have conducted intense research, found numerous flaws, documented everything and written proof-of-concept code to validate your claims.
Otherwise it's just hearsay based on fantasies.
Would you be so kind and share your research and proof-of-concept code with us ???
