I can't get the btminter mining button to work on firefox, nor chrome. I'm running ubuntu 11.10, and have OpenJDK Java 7 Runtime and Iced Tea Java Web Start 6 installed. When I click on the button in chrome, it just downloads the bitminter.jnlp file. In Firefox, it tries to run it, but running it in Firefox isn't right as it just opens an empty window. The button ran fine on the Windows 7 PC. any ideas?
