So, I chown the firefox64 files to a new user group that includes everybody. didn't work.
The strange this is, before I ran your script on the non user screen, I use to get "need to download flash player" messages on the web page. Now after running the script , having flash work one time, when I go to a web page, I don't get the "need to download flash player" message any more. That part of the web page is just blank.
BTW, there's someone else with the same problem on another one of your threads (http://ubuntuforums.org/showthread.p...+flash&page=15)
As always, thanks for your brilliant help!!
