Thank you for your fast feedback.
1. I have tried to adapt the default webbrowser.app with the proposed settings on link:

But when I restart the browser I receive the message 'the application cann't start, doesn't find the browser app.
2. The option to restore the page after zooming I didn't find in the manual.
3. The option to inverse the background in black and the text in white, I didn't find.
Thanks for your help anyway.
