>Is there any HTML viewer left for VFP to use now that IE is dead and gone?

Edge is supposed to handle that use case as well,
even down to a wrapper for old IE PEMs.

Rick Strahl switched over from IE to Edge for his Markdown Monster App,
ran into a few troubles, but he has a tough set of features he needs to support.

OTOH he mentions that overall the experience was not worse than IE with its quirks.

A lot of trouble seems to arise when trying to call JS functions via asynch,
as the different runtimes of the Edge JS and C#/Dotnet have to match.

On his website there are at least 3 articles of the pitfalls he ran into.
Probably much more stable than any direct hosting of Edge or Chrome -
AFAIR Christoph implemented some of that for vfp, so you might search there.

upd: of course there is Selenium as well - built on JAVA with quite a few wrappers
(Java had lousy COM support, have not looked lately!) and Python does COM well.
Less methods than IE automation offered, but good support to fill in different controls.
One benefit of Selenium is that it works not only on IE or Edge, but other browsers as well.
