You need it to run 32-bit Flash on 64-bit Fedora, which is still our
recommended setup for the proprietary Flash (as Adobe does not update
the 64-bit plugin anywhere near as quickly as the 32-bit one, so it's
usually vulnerable to an assortment of widely known, critical security
issues, which is not something you want, to put it mildly). And even
when arch isn't an issue, nspluginwrapper provides isolation for
plugins; when a plugin crashes, the browser doesn't. (This is marketed
as a feature of other browsers, notably Chrome.)
