Problems with FlashPlayer and Firefox 21+? Here the solution

As many know I use Debian, and the installation of Firefox I do it manually for many reasons following these steps.

It happens that with the exit of Firefox 21, Flash Player began to present problems, not errors, but that the browser could not find it.

Normally you could use FlashPlayer in Firefox as explained in this article. But not anymore.

This is because with Firefox 21, the folder is no longer used ~ / .mozilla / plugins / for FlashPlayer, but the path changed. Now the folder plugins it is located inside the directory where it is installed Firefox.

For example, in my case, when I unzip the .tar.gz, I copy the folder firefox en ~ / .local / apps /, therefore now the steps to follow are the following:

1- I download the latest version of Flash Player for 64Bits:

cd ~
$ wget http://fpdownload.macromedia.com/get/flashplayer/pdc/11.2.202.285/install_flash_player_11_linux.x86_64.tar.gz

2- I unzip the .tar.gz:

$ tar xfv install_flash_player_11_linux.x86_64.tar.gz

This extracts 2 files and a folder:

  • readme.txt
  • libflashplayer.so
  • usr /

4- We create the folder plugins inside the directory where Firefox is installed, in my case it would be:

$ mkdir ~/.local/apps/firefox/plugins

In some forums I have seen that the plugins folder if it does not work in that path, it must be in ~ / .local / apps / firefox / browser / plugins

So that there are no problems with this, we create a symbolic link:

$ ln -s ~/.local/apps/firefox/plugins ~/.local/apps/firefox/browser/plugins

5- We copy the file libflashplayer.so:

$ cp libflashplayer.so ~/.local/apps/firefox/plugins

6- We copy the contents of the folder / Usr  to the directory / Usr:

$ sudo cp -Rv usr/* /usr

This should be enough. If for some reason it still does not work, we open a new tab, type about: config and we look for the parameter:

plugins.load_appdir_plugins

And if it is in false we put it in true.

Ready. Following these steps I already have FlashPlayer working again, although I hardly use it 😛

    Hmm. What's wrong with using iceweasel 21 with the flashplayer-nonfree package?

    At the end of the day it is Firefox 21 with Debian style and that way there is no problem.

    1.    eliotime3000 said

      You will say flashplugin-nonfree.

      In iceweasel there are no problems.

      1.    one of some said

        It is true is that the pot left me ha ha ha.

  2.   eliotime3000 said

    Dafuq ?!
    I install the flash player using the script that Debian has in the contrib repo, and so far, I have had no problems with the flash player.

    Anyway, with Iveweasel the flash player works wonders

    That doesn't happen in Chrome hehehe, that's why I like it so much hehe

    1.    pandev92 said

      chrome flash is horrible ...

      1.    cat said

        I support it

        1.    krlos said

          I also agree.

      2.    eliotime3000 said

        Me too, that's why I go to about: plugins and deactivate the pepper flash player and leave the flash player active.

    2.    hanger said

      I used chrome because flash was much better for me, but in the last update (I'm on wheezy) it started to malfunction.
      At least I ended up tipping the scales towards iceweasel (the youtube html5 test works pretty well for me)

  4.   eliotime3000 said

    The pepper flash of Google Chrome is heavy when watching videos on YouTube, so I prefer a thousand times to use Chromium instead of using Google Chrome (the plugins it has integrated are heavy in themselves and slow down the performance of the browser).

  5.   eliotime3000 said

    And adding that the flashplugin-nonfree is simply a script that downloads the flash player from adobe.com to Debian based on the architecture that has been installed.

    Anyway, the grace is in how to install the flash player manually (I tried firefox 21 and with the flash player installed from the Debian script there is no problem.

    It is strange that that did not happen to me in fedora when I updated from firefox 20 to 21 strange, but now I use GNOME Web and its version 3.8 supports flash so I do not have that problem, I invite you to try it, it is very fast.

  7.   likewho said

    So this problem applies only to Debian? because I have no problem.

    1.    likewho said

      I use Chromium, not GC x)

      1.    eliotime3000 said

        I believe you, because I also use Chromium (the nightly build for Windows) and many distros don't bother to modify the Chromium User Agent (by default, the chromium user agent always says chrome, since it is an experimental version of Google Chrome itself).

    I always install it in / usr / lib / mozilla / plugins even in this version 21 ... I clarify that I use iceweasel

    1.    eliotime3000 said

      I am more lazy, because I use the "flashplugin-nonfree" package from the contrib branch of the Debian repos and I have the flash player directly downloaded from Adobe ready to be used in all browsers.

  9.   eldebiandepepe said

    If you have a 32-bit computer, copying the file "libflashplayer.so" in / usr / lib / mozilla / plugins / should be enough ... I suppose that on a 64-bit computer it will be the same, but if I remember correctly, in the debian list in Spanish I read that someone had problems with the installation of Flash in Wheeze with the latter ... I don't know, it would be a matter of looking at it.

    1.    eliotime3000 said

      I installed the Adobe flash player through the "flashplugin-nonfree" package found within the official Debian repos (specifically, in contrib). If I had problems, I did not have them, so it may be that when installing it manually I have not used the directory that is used for all browsers (including Mozilla Firefox).

      Anyway, I have not had problems with installing the flash player neither in Iceweasel nor in Firefox.

    In firefox 21 there was a reordering of the files that are in tar.bz2. The browser folder was created and now the «chrome» folder (not to be confused with the browser) and files like mozicon128.png changed their location to inside that folder ... obviously there may be problems (my shortcut had no icon this morning: P) . It is still strange to put executables in .local ... the tutorials I have read almost always pointed to / opt and ubuntu points to / usr / lib, that could be the cause of error, since the plugins always go through lib

    Well, in Fedora and openSUSE I had no problems.

    It's funny, because I didn't have any problem with Flash on my Firefox 21.
    In particular I use the package available in the Debian repos:

    Shockwaveflash 11.2.202.285
    icedtea-web plugin 1.3.2

    Firefox I install it easily with:

    I download the package, unzip and copy the content to / opt. Then I create the symbolic link from / opt / firefox / firefox to usr / bin / firefox and create the launcher in the KDE menu and that's it 🙂

    1.    eliotime3000 said

      I had no problem installing "flashplugin-nonfree" on Debian, since using the Flash Player I have had no problems using Iceweasel and Chromium.

      Let's see if with OpenJDK and IcedTea it is useful to download videos with keepvid.com

        Off topic:

        In the ZPanel installation, I have made the serious mistake of not having activated the web server, SQL Server, DNS Server, file server, mail server and ssh server options, since the script works if these components are installed (apache, MariaDB ...) and when emulating it in the virtual machine, you must use the bridge adapter to be able to enter the panel without having to suffer subsequent consequences (as was my case).

          PS: Install PHP or if not, you will download a file without an extension. Do it.

    Well, I don't understand this much, I have my firefox on wheezy installed manually / opt and the flashplugin-nonfree from the repos and everything is perfect after updating to firefox 21.

    I don't know why this mania of updating everything every so often, I have installed Nero 7 since 2006, the VLC worked spectacularly for me ... until I update it, now every now and then it tells me that it can't find the RML (or something like that) and it doesn't you can open the DVD. Every day I have more anger at the updates. Yoono in Firefox was a bullet now I don't know why every so often I have to reload the users. Just in case Thunderbird and Firefox do not update them or in hell. I am looking forward to installing Debian 7 (I must buy another HD) and having all free software and without updating for years….

      Man if you are not always updating to the latest stable debian it can come in handy or even centos. But having updated software provides you with new functionalities, supposedly performance improvements, support for new features, bug fixes, the latter for me very important in web browsers, well and in general.

      You do not have to have exactly the latest version, for example, in a recording software because it does not seem important to me or even for vlc if the versions you have are good for you, but for other types of software, such as a web browser, it is important .
