But regarding the pop-up xss warning window on Linux ubuntu 14.04/Linux Mint 17.3 and firefox 57.0.1 it only shows a white empty window.
Using the same browser version on my windows 7 laptop it works as shown on this picture: https://hackademix.net/2017/12/01/noscr ... el-normal/
I am using noscript version 10.1.5.1 on both computers.
I used the same test script as shown in the above link.
