Yuck! Don't do that :-) Quite apart from the question "what name"
("mozilla", "mozilla-firefox") there is the question "where", and
"which of the ones you find".

Try the other thing I suggested, which is to use the MimeType stuff.
This is the mechanism an email client uses when clicking on an HTML
link. So, use
	wxMimeTypesManager::GetFileTypeFromMimeType
to get a wxFileType * for your HTML file, and, e.g.
	wxFileType::GetOpenCommand

Use wxExecute to run it.

But could you also report a wxWidgets bug that wxLaunchDefaultWebBrowser
is fundamentally broken on all known distributions? I take it you have
tried a sample program with 2.6.3 (stock) and 2.7 (CVS_HEAD) rather than
just our own code. This one really ought to be fixed and it may be
that getting people to fix it is in the long term a better solution
than playing around with MIME-types.
