Linux – Firefox does not find Flash Player Plugin on Centos / Linux

firefoxflashlinux

In our production environment we are installing a Web-based product. The Operating System is Centos 6.5. For this product, we have installed Firefox-33 and Flash Player 11.2.202.406-release.x86_64. The problem is that Firefox starts, but it does not detect Flash Player Plugin.

The following error message is reported when we run Firefox:

1411663263429 addons.manager ERROR Exception calling provider startup: [Exception… "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [mozIGeckoMediaPluginService.addPluginDirectory]" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: resource://gre/modules/addons/OpenH264Provider.jsm :: OpenH264Provider.startup :: line 271" data: no] Stack trace: OpenH264Provider.startup()@resource://gre/modules/addons/OpenH264Provider.jsm:271 < AMI_callProviders()@resource://gre/modules/AddonManager.jsm:875 < AMI_startup()@resource://gre/modules/AddonManager.jsm:750 < AMP_startup()@resource://gre/modules/AddonManager.jsm:2322 < AMC_observe()@resource://gre/components/addonManager.js:55 <

Questions are:

  1. Why is Firefox not detecting or connecting to Flash Player Plugin?
  2. Is Gecko Media Plugin not functioning, or not able to detect Flash Player?
  3. What steps should we take so that Firefox can detect the Flash Player Plugin ?

We would really appreciate any help in this regard. In case this is not the right (sub)-forum, please advise where we should post this question.
