Gnash is an open source player for Adobe’s Flash format. It can be used as an alternative to Adobe’s proprietary player. The upcoming Ubuntu 7.10 release includes automatic installation of either Adobe Flash or Gnash. I decided to put this feature to the test in Ubuntu 7.10 Beta.
Surfing to a page with an embedded Flash video causes Firefox to offer to install the missing plugins. I chose the option to install the Gnash player.
