Chrome only future for Flash on Linux
Adobe has announced that in future, the Flash Player for Linux will only be available through Google as part of the Google Chrome browser and not as a standalone download. The shipped plugin will also only support Chrome's plugin API. The changes will take effect after the release of Flash Player 11.2 later this year.
In a blog posting, Adobe said it had been working with Google on developing a replacement for the Netscape plug-in API that Flash Player currently uses, called PPAPI or Pepper. Pepper is designed to be a single modern API for plugins within the browser with an effective abstraction layer hiding the different types of browser and API.
Adobe has worked with Google on this as Flash Player.
