I am using FF 30 on Ubuntu 14.04. I installed flash and youtube is working fine. However some videos from some sites aren't playing - Foot ball videos (FIFA) and Cricket videos (Starsports) etc. Just black screen appears.

Same videos are working fine on Google chrome

Some links which I couldn't play on Firefox

This is looks like this is to do with the version of Flash - Linux systems now have to use an old version of Flash.

The short answer is use Google Chrome - command line instructions for installing it are here.
Chrome uses an embedded version of Flash (Pepper Flash), which is still updated to the latest version on all distributions.
You can also use Chromium and the Pepper flash plugin:enter image description here

Other answers - which are better for Firefox users (like me):

  • Use FreshPlayerPlugin, which borrows the plugin from Google Chrome. Instructions for 14.04:

    sudo add-apt-repository ppa:nilarimogard/webupd8
    sudo apt-get update
    sudo apt-get install freshplayerplugin

    You can then open about:addons in Firefox, and enable the plugin under 'Plugins'. It may be easier if you remove the original Flash plugin first, as Firefox seems to prefer using that. It does seem to work (the usual Flash plugin doesn't):

  • Use Pipelight (instructions here) which sort of uses Wine to pretend to be a Windows machine.

I tried freshplayerplugin and videos are playing fine, but the plugin is still not stable and is crashing very often (even in youtube) – mac Jul 12 '14 at 17:58
A fairly rubbish solution to that would be to keep the standard Flash plugin installed, and only install the freshplayerplugin with apt when you need it - its seems fairly difficult to enable one flash version and not the other version in Firefox... I'll look for a workaround – Wilf Jul 12 '14 at 18:46
That is also possible using a deb package file from here - N.B. You probably want to check whether Firefox + FreshPlayerPlugin are the same *bit (32bit/64bit). Another thing is that you may want to try fiddling with the settings in the config file - don't enable hardware acceleration. – Wilf Jul 12 '14 at 18:54
Installing it every time I need, would be too difficult. Even if I do that, since plugin is crashing on these sites as well, my purpose wasnt served. – mac Jul 15 '14 at 13:40
