FYI
Puffin Web browser will always work as that Web browser is redirected to online servers, that serve tbe Web browser, to stream the actual desktop website content from other unknown remote server locations.
This is how Puffin is able to stream most Adobe Flash Player content through iOS.
It is actually streaming a desktop version of a web browser with Flash Player installed and is transmitting this content through remote servers to iOS devices.
The issues come from where the original content is coming from as Puffin gets its content from other online servers with unknown security.
Puffin claims that their transmitted Adobe Flash Player content is secure, but I have been always dubious of that claim.
Puffin Web browser has been around for nearly 9 years, or so, and I have never used it or trusted its claims.
