I'm trying to install Flash onto my PFF installation. I've added the site to the whitelist and when I try to download the extension as per the instructions at https://portableapps.com/support/portable_firefox#plugins, I get "Firefox could not install the file at http://fpdownload.macromedia.com/get/flashplayer/xpi/current/flashplayer... because: Download error".
I've tried using the likes of MozRegKey, downloading the installer manually and installing directly to the plugins folder, copying the necessary dll to the plugins folder (which is only Flash 6) and still having no luck.
Any suggestions would be appreciated.
