Comment 1 for bug 351389

Note that currently, the 64-bit Adobe Flash Player 10 for Linux is a prerelease / alpha version, even though many people report that it works very well.

(@Mike: You mean nspluginwrapper, not ndiswrapper).

The problem with ubuntu-restricted-extras is that at this moment it depends on sun-java6-jre as well as icedtea6-plugin for amd64, which means that you get two Java runtime environments installed (Sun Java 6 and OpenJDK Java 6) if you install ubuntu-restricted-extras on amd64. The dependency on icedtea6-plugin (and OpenJDK Java) should be removed, since the current version of Sun Java 6 now includes a 64-bit Java plug-in.
