Brian McDermott's team had to come from behind twice and then needed an 81st-minute winning goal from Pavel Pogrebnyak to progress into the fourth round.
The 28-year-old was pleased with the character shown by his team-mates to turn the tie around and claims that the match was proof of their ability to find the back of the net on a regular basis.
"It was a great cup tie with some terrific goals," Tabb told reporters. "We've got the winning feeling back that we were used to last season. Hopefully this can kick us on to get a couple of good results in the league.

"I thought we were unlucky to go behind twice but we stuck at it. It will be hard to keep clean sheets in the Premier League so we have to score goals – and tonight we certainly did that."
On a personal level, Tabb admits that he had been struggling throughout the game with his fitness but was happy to have completed the full 90 minutes.
"It was huge for me to get a full game," he enthused. "Me and Jem [Karacan] were really blowing after half an hour but as the game went on I thought we got stronger. We did things right tonight and the manager is really pleased for us.
"The dressing room was buzzing after the game but we all know that Saturday is another game and we'll be ready."
