Unforunately, this plugin became pretty useless and crippled down after the take-over from Ipswitch. The macro i had been using for many years stopped working because i am using too many variables (i am using 3 variables!). Ipswitch is offering paid versions but they are mainly focused on Windows platform. I am a GNU/Linux user. Will either have to switch over to Kantu Browser Automation or continue to use old Firefox 45.0.2 with old imacros 8.9.7 version that is still working like a charm.
