    Can't Install Pepperflash in Firefox

    I'm trying to display this page properly right now, but Flash fails to work in other places as well. I assume that it's because I have an ancient version, which is weird because I've installed Pepperflash before. I'm using Firefox 41.0.2.

    I've tried using these commands:

    Code:
    sudo add-apt-repository ppa:nilarimogard/webupd8
    sudo apt-get update
    sudo apt-get install freshplayerplugin
    I have the latest version of Google Chrome installed, and I launched it, because one guide I looked at said that it must be launched first to activate Pepperflash.

    I've tried uninstalling and reinstalling Google Chrome, closing and opening Firefox, removing all non-official PPAs except this one to make sure there is no conflict, and rebooting. Nothing. Here's the full list of things I tried doing:

    Code:

    Close Firefox
    Close Chrome
    sudo apt-get remove google-chrome-stable
    
    Remove some software sources, including an old source for Pepper Flash
    
    Reboot
    
    ~~~~~~~~~~~~~

    sudo apt-get update
    sudo apt-get upgrade
    
    The following packages will be upgraded:
      firefox firefox-globalmenu firefox-locale-en firefox-locale-ja
    
    sudo apt-get update
    sudo apt-get remove freshplayerplugin
    sudo apt-get update
    sudo apt-get install freshplayerplugin
    sudo apt-get update
    
    google-chrome-stable_current_i386 (1).deb from https://www.google.com/intl/en-US/chrome/browser/
    
    google-chrome-stable
    
    Close Chrome
    
    sudo apt-get update
    
    Reboot
    Launch Firefox
    
    No change
    If I view about:addons, there is nothing called Flash in either Extensions or Plugins. I know that I have Flash because if I change Youtube to use Flash, it still works.

    All of the tutorials I found are from 2014. Is this information just outdated? What am I supposed to do instead?

    Thanks.

    Re: Can't Install Pepperflash in Firefox

    I figured out the problem. To install Pepperflash, you have to first install Flash 11 to Firefox. I don't really understand why I didn't have it since I could use Flash Youtube (or at least, non-HTML5 Youtube?), but I didn't.

    So I installed Flash 11 following these steps: https://support.mozilla.org/en-US/kb...lugin-manually

    Then I closed Firefox, removed Chrome and freshplayer plugin, and reinstalled them. Now this website says that I have Flash 19, and my plugins list Flash 11 and Flash 19.

    Hooray!

    Here are my exact steps just in case anyone needs to know how to solve this problem in the future.

    Code:
    https://support.mozilla.org/en-US/kb/install-flash-plugin-view-videos-animations-games#w_installing-the-flash-plugin-manually
    
    download Flash tar
    close Firefox
    tar -zxvf install_flash_player_11_linux.i386.tar.gz
    sudo cp libflashplayer.so /usr/lib/mozilla/plugins/
    
    sudo apt-get update
    
    Launch Chrome
    Close Chrome
    Launch Firefox
    
    Firefox now has Flash 11 instead of nothing.
    
    ~~~~~~~~~~~~~
    
    sudo apt-get remove freshplayerplugin
    
    Close Firefox
    
    sudo apt-get remove google-chrome-stable
    sudo apt-get update
    sudo apt-get install freshplayerplugin
    
    Reinstall Chrome from previous deb
    
    Launch Chrome
    
    http://flashbuilder.eu/flash-player-version.html -- Chrome Flash is 19.
    
    Chrome freezes up.
    Ctrl+C Chrome.
    
    Launch Firefox.
    
    http://flashbuilder.eu/flash-player-version.html Firefox Flash is 19!
    
    SUCCESS.

    Just a tip to speed up the process.

    Code:
    sudo apt-get install flashplugin-installer
    ... will install flash 11.2 directly from the official repos.

    Thanks for sharing.
