Auto url visits through firefox - from a txt list

I need to: Visit many urls through firefox automatically. This needs to be done through firefox only. Basically from a list of urls in a .txt file each site needs to be entered into the url field in firefox. Then a pause of 10 seconds Then loads the next url to load the page in firefox etc I have tried using Robotask, but the software is confusing to me. A simple windows automation using easy to get software as a solution is preferable. I will need a solution fast.
