Gadirova took her third straight European title on the floor with a total of 14.000 points, while Kinsella, 22, scored 13.666.
"The experience has been amazing and I cannot believe what is happening," said Gadirova, who also claimed gold in both the women's all-round and team competitions.
"It has been such an amazing championships and I couldn't have asked for anything more. That is the reason I am a gymnast because I love to perform on the floor. I gave it everything today.
"Even from being floor champion the first time was just amazing.
"And to keep defending [the title] at the moment is so crazy. I just can't believe it," she added.
Earlier, Gadirova also finished seventh in the women's beam final.
She fell forward on her landing and was awarded 6.766, but said she could not let the stumble affect her.
"I'm not always the best at beam," Gadirova said. "So I just kind of accept whatever happens, happens, and it is so hard to be so consistent on beam.
"I literally wiped it from my memory and thought floor is my chance to show it off and forget about what happened on beam."
