I installed the Flash 11 plugin using the software center (and have also removed the reinstalled it via command-line in the terminal), yet Firefox still claims the latest version of the plugin I have is 10. (And just to clarify, I have been sure to reboot both Firefox and the entire computer after installing).
On further investigation (this may be a red herring, pardon) I ran the uname -a command-line in terminal to assure that I was running the 64-bit version of Ubuntu, and received this feedback:
3.0.0-13-generic #22-Ubuntu SMP Wed Nov 2 13:25:36 UTC 2011 i686 i686 i386 GNU/Linux
I don't understand the series "i686 i686 i386". Which applies to my version of Ubuntu? Does this mean I've accidentally installed 32-bit Ubuntu?
Very much a beginner here - I've combed the threads but have so little understanding what my exact issue is that I haven't been able to find an answer.
