Changing test browser

My default browser is Fire Fox.
Is there a way to use it to text apps?

Using Start in Desktop Browser will always use Chrome.

To use FireFox, use the Deploy to Local Folder option, then use FF to open your app.

Thanks for that.
Sorry, George, you’re now dealing with an 80 year old. And I still have NS Basic/CE. I’m still using a couple apps I built a long time ago on my HP iPAQ which is still a real computer.

Ah! Ww dropped support for NS Basic/CE many years ago - nobody remembers much!

Can you clarify your question? Maybe someone knows.
