I'm preparing for CCNA from netacad website. Perhaps some of you have seen the platform, It offers a text materials next to picture or flash player objects. The flash animations work well, but I notice a problem in the console simulator. In chrome, all what I need is to left-click next to prompt (#) in order to write commands.
In Firefox, left-click doesn't work, I have to use right-click and the simulator ofter crash after some clicks, as you can see in pictures.

Packages I use :

dpkg --list|grep -i 'firefox\|flash'

ii  firefox                                    56.0+build6-0ubuntu0.16.04.2                 amd64        Safe and easy web browser from Mozilla
ii  firefox-locale-en                          56.0+build6-0ubuntu0.16.04.2                 amd64        English language pack for Firefox
ii  flashplugin-installer                      27.0.0.183ubuntu0.16.04.1                    amd64        Adobe Flash Player plugin installer

    Possible duplicate of [How do I install Adobe Flash player?](https://askubuntu.com/questions/11/how-do-i-install-adobe-flash-player) – dobey Nov 14 '17 at 19:13
  • The `flashplugin-installer` package is obsolete, and you should instead be using `adobe-flashplugin` package. However, note that Google includes their own version of Flash inside the Chrome browser. – dobey Nov 14 '17 at 19:14
  • Further on dobey's comment, this may also be a Flash version issue as well since, as you may know, Adobe no longer supports Linux for Flash after 11.2.202.350. – P05TMAN Nov 14 '17 at 19:17
  • @dobey - he has flash installed and running, but it crashes. So not a dupe of that question, but maybe another. – ravery Nov 14 '17 at 19:18
  • @ravery It's a duplicate because the question clearly shows the wrong package installed. – dobey Nov 14 '17 at 19:23

    @P05TMAN You certainly meant "Flash for Linux" and not the other way around... ;) In any case, not applicable. The `adobe-flashplugin` package mentioned above provides a fairly updated Flash version for browsers other than Chrome which already has it. Currently running version 27.0.0.183 in Ubuntu 16.04. –  Nov 14 '17 at 19:25
  • @dobey -- chrome v60 and newer no longer contains pepperflash. Coincidentally this change occured when adobe released the new flashplayer for linux. – ravery Nov 14 '17 at 19:30
  • I installed `adobe-flashplugin` but the problem persists. – jeff Nov 14 '17 at 19:38

    @dobey: You are wrong as regards `flashplugin-installer`. That package is just as valid as `adobe-flashplugin`, and provides the very same plugin for Firefox. Please read [this page](https://help.ubuntu.com/stable/ubuntu-help/net-install-flash.html) for more info. – Gunnar Hjalmarsson Nov 14 '17 at 19:38
  • @jeff I think you need to report it to the web site in question then, and perhaps Adobe, as it's a bug with the flash code. – dobey Nov 14 '17 at 19:40
  • This is a long shot, but installing the [browser-plugin-freshplayer-pepperflash](https://help.ubuntu.com/stable/ubuntu-help/net-install-flash.html#browser-plugin-freshplayer-pepperflash) package may be worth a try. – Gunnar Hjalmarsson Nov 14 '17 at 19:48
  • @GunnarHjalmarsson That gives a better results, I needed to install `pepperflashplugin-nonfree`. Now, it crashes when I use right-click. – jeff Nov 14 '17 at 20:39
  • @jeff: It surprises me that you needed to install `pepperflashplugin-nonfree`. Don't you have `xenial-updates` enabled in _Software & Updates / Updates_? If you haven't, you really should enable it. – Gunnar Hjalmarsson Nov 14 '17 at 20:52
  • @GunnarHjalmarsson It's enabled ! – jeff Nov 14 '17 at 21:33
  • @jeff: Then is your system updated (`sudo apt update`)? Asking because the version of `browser-plugin-freshplayer-pepperflash` in `xenial-updates`does not depend on or recommend `pepperflashplugin-nonfree`. (The version in `xenial-release` does.) – Gunnar Hjalmarsson Nov 14 '17 at 21:44
  • @GunnarHjalmarsson before adding `pepperflashplugin-nonfree`, the browser showed an error message a message about loading `libpepflashplayer.so` instead of the flash. – jeff Nov 14 '17 at 22:12
  • @jeff: Loading `libpepflashplayer.so` instead of `libflashplayer.so` is the whole point of `browser-plugin-freshplayer-pepperflash`. Maybe a browser restart or relogin/reboot would have made that message disappear. Since you have `adobe-flashplugin` installed, `pepperflashplugin-nonfree` ought to be redundant. Anyway, I'm glad it seemed to help. – Gunnar Hjalmarsson Nov 14 '17 at 22:37
  • @GunnarHjalmarsson I recently updated my browser from 56 to 57. Now, it uses version `27.0.0.187` and works perfectly. – jeff Nov 16 '17 at 08:38

    @jeff: Would be good if you could post the solution as an answer. It's perfectly fine to answer your own question. – Gunnar Hjalmarsson Nov 16 '17 at 13:18

Problem resolved after installing the latest version of Firefox 57 (released during the discussion).
