Fire ftp not working in FF 18? Rated 4 out of 5 stars
I had problems with Fire ftp not working with Firefox 18.0.1
...but that was when I was trying to get it working through the add-on screen/ menu.
What I ended up doing to get it working was to google "fire ftp download" then I downloaded it and installed it outside of Firefox. Now Fire ftp works great. Thankfully, I'm a college student in a web design class and I really needed the ftp. Thanks, design team, I'll be donating.
