  • Untarring problems: Your browser might have un-gzipped it for you automatically. Try just "tar xvf" instead of "tar xvfz". Also, the plugins archive isn't gzipped (it is a tarball of .tar.gz files)
  • Macintosh users: Just hold down your mouse button to get the menu instead of right-clicking.
  • If all else fails, seek our help
