I'm having the same problem - GWT firefox plugin installs, is displayed in extensions list, I can configure it. But I'm asked to install the plugin again when I access my application.
The development mode is working correctly when I access it from my windows laptop with chrome. So the issue has to be with Firefox plugin. Versions GWT 2.0 Firefox 3.5.5 Ubuntu 9.10 64bit -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
