Abbott said: "It's brilliant for the club. Leeds is something to look forward to and there's excitement about the second half of the season, but it's vital we keep the momentum going.
"It wasn't a perfect performance. We gave the ball away too cheaply at times. The goals came at the right time for us. Before the second goal we were under a bit of pressure and Scott Dobie produced a fabulous finish at a key time, then Matt Robson's goal was sensational and worth the admission money alone."
Bradford played with 10 men from the 39th minute when defender Simon Ramsden was dismissed for a second yellow card after pulling back danger man Robson.
Abbott added: "Bradford rolled their sleeves up and had an even bigger go after the sending off. Matt was causing him all sorts of problems and he was always running the risk of a red card."
