I have installed the adobe-flashplugin package from the partners source and it worked straight away for Chromium. Firefox is stuck to the old Shockwave Flash 11.2 plugin, which I've disabled.
This page https://wiki.ubuntu.com/Chromium/Getting-Flash says the plugin should work for both browsers.
I'm on Ubuntu 15.04, Firefox 40.0.3
Are there any extra steps I need to take to add it to Firefox as well?
flashplugin-installerwhich I had andadobe-flashpluginwhich you use and both show up as version 11.2 in Firefox for me. I don't have Chromium so I can't check how it looks there, but I would expect the same? – Byte Commander Sep 7 '15 at 10:36
