Thanks for the information Sampei Nihira.
I did a web search and also found the site for Advanced Chrome. I tried installing it but Norton Security removed some parts so I could not try the browser.
I'll have to read more about New Moon, and Basilisk. As I best understand, Basilisk is not yet finished being developed. So try? Maybe, maybe not. More searching and reading needed, first. I know there is a section on a forum for Basilisk. New Moon? Need more reading.
As for Advanced Chrome, that was what I wanted to try on the Vista machine. No point in trying it on the Windows 10 machine, since Firefox 59 and Google Chrome 65 work very well on it.
System Intended for Alternative Browsers:
Windows Vista, s.p.2
Browsers -- SlimJet 11, Firefox ESR 52.?.?, Opera 36, Pale Moon 27.8.?, Internet Explorer 9
