I am using Windows 7 on a desktop and my browser is firefox. Went to http://fireftp.mozdev.org to download fireftp. The screen displays fine. I clicked the download link and got the message that "firefox prevented this site (fireftp) from asking you to install software on your computer". I clicked the 'allow' button. A progress bar flashed very briefly and disappeared. Then the message "The add-on could not be downloaded because of a connection failure on fireftp.net". I first tried this on Wednesday 1/13/15 and tried everyday since including just now (1/17/15). On Thursday, I uninstalled firefox and re-installed it in case that was the problem, but it made no difference. Thank you in advance for your help! Ron S
