Modify or add 2 funtions to an existing FireFox extention

Hello there, I'm looking for someone who can change, modify or add a funtion to an existing FireFox extention called AnonymoX. What I want you to do is to simply add a function that allows to rotate IPs every (X) hours (set), and to automatically refresh the IP if it encounters an ERROR (ergo, if the IP is banned and therefore cannot access to the website). Also, FireFox has to start with Windows, and iMacros (another FireFox extention) has to start with FireFox (automatically), with pre-configured sets. Check the images bellow, for a better understanding: Original content: [login to view URL] Desired content: [login to view URL] ERROR screen: [login to view URL] Link to the Extention: [login to view URL] Those are the 4 changes I want. I'll list them, to make it simple: 1 - Rotate the IP's every (X) hours (set) on AnonymoX Extention; 2 - Automatically refresh the IPs of AnonymoX Extention when encountering an ERROR; 3 - Firefox and iMacros Extention need to start-up with Windows, automatically, with pre-configured sets; 4 - To be explained in private, has to do with connecting issues.
