Hi, Matt here and I can help you - used to create AutoIT scripts in the past yet I see AutoHotKey is software branched from AutoIT so I expect no problems.
I understand your requirements ("Close firefox and connection after start a new script." means running a script in a loop or scheduled with Windows AT service, right?).
If a script cannot be done with AutoHotKey (and AutoIT is not an option - here I'm somehow certain it can be implemented) then I agree to not get paid for this project.
Looking forward to your reply,
Matt
UPDATE: lowered bid a small yet cannot go lower (have registered business).
