The link to the Firefox Nightly 64-bit version is not linked to where it starts a download. If you go to https://portableapps.com/apps/internet/firefox_portable/test#nightly and click on the download now button for Version 41.0 Alpha 1 Pre Rev 2 x64, it just goes to a Sourceforge page with a directory and nowhere to download the portable app.
It should be working now. Rev 2 was from the previous release and inadvertently left on the page when it was updated. Sorry about that.
Sometimes, the impossible can become possible, if you're awesome!
Works great! Thanks!
