Beta News – Flash Player NPAPI for Linux

Flash Player and Linux

Linux users have access to both NPAPI and PPAPI versions of Flash Player.  However, for the last four years, the NPAPI version has been held at 11.2 and regularly updated with only security fixes while the PPAPI version (used in Chrome and Chromium based browsers), is in line with the standard Windows and Mac releases.

Today we are updating the beta channel with Linux NPAPI Flash Player by moving it forward and in sync with the modern release branch (currently version 23).  We have done this significant change to improve security and provide additional mitigation to the Linux community.

In the past, we communicated that NPAPI Linux releases would stop in 2017.  This is no longer the case and once we have performed sufficient testing and received community feedback, we will release both NPAPI and PPAPI Linux builds with their major version numbers in sync and on a regular basis.

Because this change is primarily a security initiative, some features (like GPU 3D acceleration and premium video DRM) will not be fully implemented.

If you require this functionality, we recommend that you use the PPAPI version of Flash Player.  That said, we believe that the new NPAPI build represents a significant step forward in functionality, stability, and security and look forward to hearing your feedback.

Currently we are distributing 32 and 64 bit binaries only, we will package these in proper installers after additional testing and feedback. Users should manually back-up their existing Flash Player plugin file from the appropriate system plug-in folder and copy the new binaries into place to use them.  Please note that our initial release does not support Fedora based distributions.  For more information, see our release notes.

You can download the new NPAPI binaries today by visiting the Adobe Labs download page.

  1. it is very help full need full

  2. Sip good, we would like Adobe Air update to Linux too….

  3. jack66 says:

    The 32 bit version crash on my Firefox 45 on Mageia 5.

  4. ZenitharChampion says:

    Thank you guys! It’s annoying that VDPAU is crashing with GLIBC > 2.12 Flash Player is the only one solution to get hardware accelerated h264 in browser, so thank you for update!

  5. zmj says:

    hey thats great, you should give linux full speed on the gpu drivers

  6. Udara Madubhashana says:

    This is just awesome 🙂
    Hopefully now with open platforms like Snap & Flatpack Adobe creative suite will comes to Linux. Any progress or any news about it ?

  7. Timur says:

    You write that you recommend to use PPAPI version if I require DRM. But PPAPI version on Linux doesn’t support DRM.

  8. Iiro Laiho says:

    Would it be possible to offer the PPAPI version as a separate download instead of bundled with Chrome only?

  9. Kyl416 says:

    Yeah small problem, the PPAPI version of Linux Flash that ships with Chrome does NOT support DRM. Which means no WatchESPN, no WWE Network and no other TV Everywhere sites.

    I’ll stick with 11.2 NPAPI until you ship a version with DRM on Linux.

  10. James D. says:

    That’s good news.
    But please, please, please, please support AIR on Linux.
    That would be awesome.

  11. Mark Langdon says:

    This is good news. I run a very tiny environment, but with several platforms, Android, OSX, iOS, Windows, and Linux. Linux is the best, and most stable. If I have something weirdly difficult, or financial-critical, it is Linux that I prefer to use to get the job done. And if we want to see video, Flash is typically used. Providers support Flash, and it has been debugged by repeated use in the real (and increasingly nasty) world. Good decision not to worry about GPU 3D acceleration and DRM nonsense. Most “enhancements” are bloatware nowadays – just tailfins and “chrome” (in the Old School meaning of that word! ) . For business people and adult users, Flash has matured into a reasonably stable and viable product. As security issues and exploits are discovered, it gets patched, and one can update the plugin, or the binary. This is in contrast to the annoying game the OS-vendors play, where the entire development effort seems targeted at forcing users into costly (and rarely beneficial) routine upgrade cycles.
    Has everyone not noticed this lately? With every “upgrade”, system reliability degrades. Whether it is your banking site (that now no longer works right), or the lovely awful failure of the British Airways baggage handling system I saw today, modern software seem to be in a reliability crisis. Code is never allowed to mature, and be recognized as *completed*, before some kid starts “re-factoring” it – which often means “breaking” it. Flash is used because it actually works.
    And for folks like me, out on the edge of the net, it actually works rather well. For example, we have a wimax link which just gets line-of-site to the local tower. But I was able to use Flash (Ver. in Firefox ver. 46, to stream the video+audio from the recent Linuxcon in Toronto. Everything worked flawlessly (to my surprise!) And because Flash has been beat on, attacked, updated, patched and repaired numerous times, it has the virtue of being a mature and rather stable product.
    Glad to see Adobe plans to keep it working on Linux. This is a wise and sensible decision.

  12. exvito says:

    Welcome change. Congrats. 🙂

    Any plans for re-investing in AIR on the Linux desktop platform?

  13. Andrew says:

    Great news! What’s about Air on linux?

  14. Arvo Sulakatko says:

    how about adobting Vulkan API for flash and AIR

  15. Mark B says:

    Thank you for doing this. I’m sure many Linux users will be happy too.

  16. Federico Gilberto Barberis says:

    Thanks about not abandon to linux’s users…

  17. Can you elaborate on the lack of support for Fedora? I just tested your 64-bit download on Fedora 24, and it appears to work. I copied it to my mozilla plugins directory, restarted firefox, and there it was. (I got an AVC before I ran `sudo /sbin/restorecon -v /home/mattdm/.mozilla/plugins/`, but it seemed to function even without.)

  18. Lewis Donofrio says:

    What about PowerPC Arch, these platforms would benefit immensely by having flash working again.

  19. Boris Burger says:

    This is very positive news for our company (IBL). We have developed several rather complex professional meteorological applications over the course of last 5-6 years in Adobe Flex and seeing Flash Player properly maintained on Linux again gives us some breathing space before migration to JS based applications. It will also make our end users feel more secure.

  20. dilworks says:


    Please, please, pretty please: let Flash fade away!
    Let competent developers migrate to the standards-compliant, vendor-neutral, multiplatform HTML5+JS frameworks! Even Hollywood managed to get away with its anti-consumer DRM stuff on HTML5, so is there really any need for Flash anymore!? (Please don’t bother answering that question)

    If a site REQUIRES me to use Flash, that’s a site whose services I will never use, and they will never get my money anyway.

    • Chris Campbell says:

      We’re not forcing you to install Flash. We will, however, make it available to those that need / want to view content that requires it. We’re also absolutely committed to making sure our customers are as secure as possible, which requires regular updates (at least until the bad guys decide to move on to the next target)

  21. Paul says:

    What about Acrobat Reader for Linux? Will they start supporting that again?

    • Just in Beaver says:

      Acrobat Reader? Probably not, unless the demand skyrockets. Why would you want to run it on a FOSS distro?

      There are alternatives, including but not limited to “Evince.”

      Check your distro’s repository and Google for additional FOSS programs for PDFs.

  22. Bung Xung says:

    Adobe Air ( > 2.6 ) for Linux, please!

  23. Ali Yousefi Sabzevar says:

    Fedora is a big distribution and has a large amount of users and developers behind it.
    Would you have plan for supporting Fedora in next versions?

  24. CarnivioN says:

    Does this mean the content debugger of latest version will release? and, what about latest Air runtime for Linux? Will they start supporting that again?

  25. Kenny says:

    From someone who uses flash player everyday i want to say thank you. Was easy to install, just droped in a newly created “plugin” folder at home/myusername/.mozilla and 2 minutes latter I was watching pc principle kick ass.

  26. Hagen says:

    Unfortunately, doesn’t seem to work at our servers (running CentOS 6.8):

    $ ldd /usr/lib64/flash-plugin/ > /dev/null
    /usr/lib64/flash-plugin/ /usr/lib64/ version `GLIBCXX_3.4.15′ not found (required by /usr/lib64/flash-plugin/
    /usr/lib64/flash-plugin/ /lib64/ version `GLIBC_2.15′ not found (required by /usr/lib64/flash-plugin/
    /usr/lib64/flash-plugin/ /lib64/ version `GLIBC_2.14′ not found (required by /usr/lib64/flash-plugin/

    Any clues?

  27. AngryPenguinPL says:

    To Adobe devs. Guys, why you release not complete Flash player for Linux? If you doing it, please make it feature sync with Windows and Mac. Give us fully features app, not semi-app but full app with support for DRM and GPU 3D.

    • AngryPenguinPL says:

      I forgot. Im happy to see to new Flash release for Linux and I want say -Thank you – to Adobe devs. But Im also need this few missing features in new Flash player. Can you guys?

  28. AngryPenguinPL says:

    I see one issue.
    This Flash 23 plugin work but not on Twitch page. When I trying watch stream on Twitch I see only back screen and only sound work fine – without video. When I switch to 11.2 Flash – Twitch working fine.
