addmefast error

Hi, if u ran the iMacros in your firefox so sometimes some user face the problems like u close the popup very fast, points is out of range or some errors so i solved all this errors by creating the new firefox profile instance. How to create new Firefox Profile Instance? On windows Press Start...

I am trying to add a Facebook post link to AddMeFast so I can get shares on it but when I add it I get a weird error. It says You cannot enter facebook urls in this section. To get the direct link for the share I use sharelinkgenerator. What am I doing and it doesn't work?
