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 then type in search : Run and Press enter then in the Box which will popups type this: firefox.exe -p if u are already running firefox in process so type: firefox.exe -p --no-remote then create new firefox profile and make sure u unchecked the box: Do not ask at startup so when u try to open the firefox.exe so the profile box will show up and select the new created profile and install iMacros from the add on store did like u did when u install new firefox from the firefox website btw after installing the iMacros login in addmefast and choose the script what u want to run that's it all errors will fixed. thanks. Tip: You can create instagram accounts and firefox profiles example: if u create 3 account for insatgram so create 3 firefox profiles and run firefox multiple time at the same time.
