checking Plugins, I always get Flash player outdated!

What is the exact version listed for Shockwave Flash in the Add-ons Manager, Plugins category?

I discovered that Better Privacy Changed downloading folder to removable.

What does that mean? All folders can be deleted. And how is your download folder related to a Flash Player problem?

even setting FF several times to its factory setting is not helpful. 

That's to be expected, since your Flash Player data isn't stored under your Firefox profile folder.

1. Flash player version 13.0.0.214 2. as soon as Flash player installed, it is removed automatically from downloads and FF shows outdated plugin

That's the latest version, and you can see above under Question Details - More System Details that it's available to websites.

Since I don't see any obvious issues, I suggest you perform a clean install of Flash Player as described below. It's admittedly tedious, but it's an effective cure-all for most Flash Player problems.

1. From the following page, save the uninstaller somewhere handy, like the desktop.
   • Uninstall Flash Player for Windows | Adobe Support
2. From the following page, save the installer for other browsers. If you also use Flash Player in Internet Explorer, also save the ActiveX version.
   • Direct downloads of Flash Player for Windows | Adobe Support
3. Exit all applications.
4. Run the uninstaller.
5. In Windows Explorer, try to open the following folders. If they still exist, delete them manually.

   • C:\Windows\system32\Macromed\Flash\

   • C:\Windows\SysWOW64\Macromed\Flash\

   • %AppData%\Adobe\Flash Player\

   • %AppData%\Macromedia\Flash Player\

6. Restart your computer.
7. Run the installer for other browsers.
8. Run the ActiveX installer if you downloaded it.

If you continue having issues afterwards, please attach a screenshot of the problem.
