There are simple and great web site download tools that allow to create a local mirror of simple sites having no JavaScript infrastructure behind. However, sometimes there cases when a site looks simple (and even is old enough to be a real "web 1.0" site), but none of such download tools are able to make a mirror of it. I've tried to make a local mirror for this fan site (for example, it has some transcriptions that cannot be found elsewhere, and some more rare stuff) using HTTrack Site Copier, Free Download Manager, and wget. All of them made simple mirrors lacking a lot of content. I saw some scripts at those pages, and probably that prevents from mirroring.
How can I mirror a web site with simple JS enabled? Perhaps, there's a web browser-driven solution that could support JS out of box (any browser extension, etc)?
Thanks in advance.
