There are no "windows" browsers that will work under Windows 3.0. The first beta versions of Netscape/Mosaic were from late 1993, and Windows 3.1 was introduced in April 1992, so Windows 3.0 was pretty much obsolete by the time they started working on even the beta versions of Internet browsers.
IE/Netscape/Mosaic etc. all require at a minimum Win 3.1 and a 386 CPU.
Sorry to say, with Windows 3.0 you're stuck using a DOS browser.
