IIRC it should be able to be made to work since it does everything a browser does, found this search result, though it has been a while since I used it myself at all. Another thing you might try that has worked for me is iMacros, that’s a little simpler and more basic than Selenium but should work for what you say you want to do.
Well if I was doing it I probably would be trying to focus on browser emulation to avoid having to dig into those sorts of details. It sounds like OP is a beginner and needs a simple method.
