When I click “Browes Mirrored Website”, a new Firefox tab opens but
completely blank.
Tried pressing F12 which opened the Web developer Tool, clicked the
“Network” tab, expanded the first item but there is no “Get” request,
only a “Post”.
In the “Post” request, I do find in the “Request Headers” a “Host:
c. contentsquare.net”.
I used the “c. contentsquare.net” in the "Additional HTTP headers" of "Set
options" tab 
Also deleted what was in the "Browser identity" and selected "(none)" in HTML
footer.
Still get the new Firefox tab opens but completely blank.
Mirrored “https://www.httrack.com/ “ and it open fine and links work.
I am using Windows 11, any suggestions?
