It's possible change flash settings on your computer at this URL:

http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager03.html

However, given that Macromedia has no problems setting LSO cookies on your HDD that you cannot find, I am a little bit skeptical that the settings I've tweaked there would be saved. So, I'd like to be able to look locally on my PC and verify the settings.

Where can I find the settings for Flash locally? Surely the plugin cannot be heading to Macromedia itself for them (that is a future too bleak to contemplate).

I am running Ubuntu 10.04.

Thanks, Joe

Newer versions do not use this file anymore. –  Braiam Aug 18 '13 at 18:15

It seems like settings are stored under ~/.macromedia/Flash_Player. Playing with the setting applet you linked changed files under ~/.macromedia/Flash_Player/macromedia.com/support/flashplayer/sys.

That seemed to store the saved data (cookies and downloaded flash files), but then I can remove access to that dir and still reach my saved macromedia settings –  Joseph Mastey Mar 3 '11 at 18:35
