Add-ons • Issues With Flash On Linux

Hello, I’m running into a lot of issues trying to get Flash Player working on my system.

To give some background: I have a Dell Dimension E310 running Q4OS with the i386 (32-bit) version. All of my applications are also 32-bit. I tried switching to 64-bit at one point, but it was too resource-intensive for my hardware and couldn’t keep up reliably.

The issue happens when I try to pair my Pale Moon installation with a Flash NPAPI plugin. I’ve tried several different versions of Flash, and they all fail in the same way:

  1. I copy the lib.so file into Pale Moon’s plugins directory.
  2. Everything looks correct, and the plugin shows up in about:plugins.
  3. In about:plugins, I select “ask to activate” for the Flash plugin.
  4. I visit a site I know contains Flash content.
  5. The site loads and shows “click to activate flash”. After I click, it fails and tells me to “reload page to try again.” I reload, briefly see a white screen flicker, and then nothing else happens.

Does anyone have suggestions for what I should try next, or what might be going wrong with Flash NPAPI on my specific setup?
