I install AmigaSys 3 for WinUAE with the workbench 3.0 ADF

It is working fine, but when i go to the internet thru browser "IBrowse" it gives a message saying that the browser will only work for 30 minutes ???!!!

What can i do?
To be honest i dont remember anything from the workbench time.

Can you tell me a browser to download compatible with Amigasys/AmigaOS3.9 ?

AmigaSys can read ADF files? What kind of file should i download? ADF? DMS?

Thanks
