I keep getting a message: "only a single instance of this application can run..." I have followed the instructions for enableing Flash/Firefox. When I open add ons/extenstions Flash isn't listed. Suggestions?
You won't find it in "Extensions". It's listed under "Plug-ins" if it's installed.
Thanks for your answer, Mike. I finally found what I needed to make the
plug in work on Mozilla's support page. Thanks again!
