The teams -- normally conservative offensively -- opened things up in a five-goal second period when Boston blew leads of 2-1 and 3-2.
Trailing 3-2, the Panthers struck quickly and scored twice. Florida coach Jacques Martin felt his team benefited from being aggressive with the puck.
"I think some people are finding the net, but also I think moving the puck out of our zone has helped," he said. "I think we have done a better job of going to the net."
With Marc Savard in the penalty box for holding, Jokinen took the puck out of his own end, cut between a pair of defensemen before beating Tim Thomas between the pads with a backhander at 16:23 for his team-leading 28th goal.
On the ensuing shift, Booth scored out of a scramble in front, banging home a shot from in close.
Boston coach Claude Julien considered pulling Thomas after the second goal, but knew it wasn't the goalie's fault.
"There was some thought there. I'm not going to deny that," he said. "But our whole club kind of collapsed there."
Thomas finished with 21 saves.
"You usually get better as the game goes on," he said. "It just went backward. You've got to forget about it on one hand, but on the other you've got to make sure it doesn't happen again."
Julien was upset that Jokinen was able to go up the ice so easily.
"We usually don't let guys carry the puck from one end to the other," he said.
Horton redirected Stephen Weiss' shot from the point between Thomas' legs for a power-play goal, making it 5-3 early in the third.
Boston had taken a 2-1 edge when Murray one-timed a shot inside the left post from the slot at 2:46 for his first goal since Dec. 12. He returned to action for Friday's 3-2 shootout win in Buffalo after missing 19 games with a hip flexor injury.
Zednik's second of the game tied it at 2 when he batted his own rebound over Thomas' right shoulder at 11:08, but the Bruins regained the lead on Sturm's 19th that completed a 3-on-2 rush.
Boston had taken a 1-0 lead when Chara poked in his own rebound for a power-play goal 2:19 into the game. The Panthers tied it on Zednik's first of the night when he one-timed Jokinen's cross-ice pass by Thomas.
Vokoun had his sixth assist of the season on Jokinen's goal. ... Zednik has six goals and three assists in four games. ... Thomas has lost his last three starts. ... Vokoun has started 51 of 56 games this season. ... Sturm earned his 200th NHL assist.
