Hi rivenmaster, when Firefox can't find Flash after restarting Windows, can you confirm:

  • Flash (NPSWF32_11_7_700_224.dll) is where it is supposed to be:

    32-bit Windows: C:\Windows\System32\Macromed\Flash
    64-bit Windows: C:\Windows\SysWOW64\Macromed\Flash
  • Firefox is set to scan the registry for plugins:

    In the about:config preference editor, plugin.scan.plid.all=true
    (detailed steps)
  • If you are familiar with RegEdit, can you check that the correct path to the Flash plugin is still listed here:

    32-bit Windows: HKEY_LOCAL_MACHINE\SOFTWARE\MozillaPlugins\@adobe.com/FlashPlayer
    64-bit Windows: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins\@adobe.com/FlashPlayer

If those ingredients are in place, Firefox should find Flash.


In case the plugin registry file has become corrupted, you could rename it to force Firefox to regenerate it. Here's how:

Open your current Firefox settings (AKA Firefox profile) folder using

Help > Troubleshooting Information > "Show Folder" button

Switch back to Firefox and Exit

Pause while Firefox finishes its cleanup, then rename pluginreg.dat to something like pluginreg.old

Restart Firefox and check the plugins list. Any improvement?
