Very useful program... until now. It has just started to transfer files as blank. For instance a 2KB web page will transfer as 0KB. Same page transferred to same host with filezilla or cuteftp transfers as 2KB. Version 2.0.7 and FF 16.0.1

Hm, not sure what could be the cause of the issue in your particular case - perhaps some firewall software? If it works in Filezilla perhaps try Reseting Firefox: http://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems
