Internet
Explorer 5.0 or later Supports Yiddish! See A Users' Guide to
Yiddish on the Internet for extensive notes and tips on setting
this up.
Bonus: Outlook Express, an email client which comes with Internet Explorer, also works for displaying Yiddish in email, assuming it's in the right encoding and that the Internet Explorer has already been configured to display Yiddish properly.
Opera
7.20b7, for Windows, seems to be the first version of Opera usable
and suitable for Yiddish. There are versions available for Unix, and
these have the same Bidi support, but these seem to be less stable.
