On the Mozilla mailing list, Mozilla’s Robert O’Callahan argues that supporting Pepper would be a waste of resources.Mozilla is trying to build HTML5 and web technologies — they want web developers to use that, not to make shiny new Pepper plug-ins more tempting.Opera notes that Opera for Linux may include the Pepper Flash plug-in in the future — they’re working with Adobe on this. It’s already been purged from mobile devices — Adobe ended development for Flash Player on Android years ago.It’s still used for many desktop sites, but the web and Adobe itself are moving towards HTML5 and other web technologies integrated into browsers.The open-source Chromium web browser also supports Pepper plug-ins.However, Adobe doesn’t distribute the Pepper Flash plug-in separately.The new version of Opera, currently available only as a “developer” version on Linux, is based on Chromium.It supports the Pepper Flash plug-in, but you’ll have to install it in the same way you do for Chromium.
The Mozilla Wiki page on the subject has a terse message: “Mozilla is not interested in or working on Pepper at this time.” The topic was also discussed on the Mozilla bugzilla.
It’s clear Flash is no longer as much of a priority, and Adobe will eventually wind down Flash Player development for all platforms.
Adobe’s Flash development tools can already export to HTML5.
Unfortunately, the package won’t automatically update the Pepper Flash plug-in.
This is a big deal because Flash has so many security holes that frequently need to be patched.
