My default browser is Firefox, but when I wish to save a web page, I always use Windows Explorer.

I copy the web address from Firefox open Windows Explorer and paste the address into the Windows Explorer address bar and hit enter.

Then File/SaveAs/WebArchive, single file (*.mht)

That way all you have is one single file which can be placed in any folder one wishes.

I have not used this method on HotCopper but it's worked well for years.
