Comment on Folx

I used this successfully for about a week but the downloads were slow, so I read about how to improve the speeds. I'm in an Intel iMac using Apple Airport Extreme, and I went in and tried to open a window, and after doing so all Flox Downloads ceased to download anything but still and Download attempted in Firefox is assigned to Flox to download and nothing happens.
Very frustrating, I spent about two weeks trying to read everything I could to solve that fail# but just confused myself even more. I've given up on Flox.
