The Packers lost to the San Francisco 49ers in a Wild Card Round playoff game in 1998.
Favre had rallied the team with a touchdown pass to wide receiver Antonio Freeman with 1:56 remaining in the game to put the Packers up 27–23.
However, Steve Young responded with a touchdown of his own to wide receiver Terrell Owens with three seconds remaining to end the Packers season.
Favre and the Packers failed for the first time since 1994 to at least reach the NFC Championship.

Favre led the Packers to an NFL record 29 consecutive home wins (25 regular season, 4 post season) until they were defeated by the Minnesota Vikings on Monday Night Football, Oct. 5, 1998.
Favre's record for consecutive regular season home wins stood until 2010 when Tom Brady led the New England Patriots to a home victory over the New York Jets Dec. 6, 2010.
Despite Brady and the Patriots surpassing the regular season mark for consecutive home victories, the combined regular season plus post season mark remains an NFL record for Favre since the Patriots had their combined regular and post season streak interrupted by a home playoff loss to the Baltimore Ravens Jan. 10, 2010.

During the final game of the 1999 NFL season, Favre and the Packers were involved in what has been described as a bizarre tie-breaking scenario which resulted in four teams that finished with 8–8 records where two of the teams would qualify for the playoffs and the other two would be eliminated.
Going into their season finale against the Arizona Cardinals, the Packers needed to win their game, have the Dallas Cowboys lose their game later that afternoon, and also needed the Packers to win the net points scored tie-breaker vs. the Carolina Panthers (who were facing the New Orleans Saints).
The Packers and Panthers were playing during the noon time slot and the Packers held a net eighteen point advantage.
As the game progressed, Carolina was winning their game by a sizable margin to the point that they had overtaken the Packers in net points for a brief time.
Since both teams were neck and neck for the tie-break advantage, both teams were frantically trying to score as many points as possible despite leading on the scoreboard by a sizable margin.
The Cardinals and Saints also tried to score frantically as the game progressed to stop their opponents from gaining the net points advantage.
Ultimately, the Packers prevailed in net points by +11.
In the end however, the Cowboys won their afternoon contest against the New York Giants to claim the final playoff spot and thus eliminate the Packers from playoff contention.
Over a 26-minute period (from 2:51pm to 3:17pm) Favre led the Packers on a 99-yard touchdown drive utilizing a hurry-up offense despite leading their game 35–17 culminating on a 32-yard touchdown pass to Bill Schroeder, and then shortly thereafter threw a 43-yard pass down to the one-yard line to set up another score.
The Packers won their game 49–24 and the Panthers won their game 45–13.

On March 1, 2001, Favre signed a 10-year contract extension worth around $100 million.

In the regular season finale of 2001, Favre was the target of minor controversy when, in a game against the New York Giants at Giants Stadium, he was sacked by the Giants defensive end Michael Strahan.
It was Strahan's lone sack of the game and gave him the NFL's single–season sack record of 22.5, which topped Mark Gastineau's reco rd of 22 set in 1984.
The controversy (Favre fell over unusually easily) has followed Strahan continuously since he set the record.
Jim Fassel, Strahan's coach in 2001, said that when a respected athlete like Strahan gets close to an all-time record, sometimes opponents want him to break it.

By the end of his tenth year in the league as a starter, Favre had thrown 287 touchdown passes, which was more than 100 touchdown passes than the second-ranked quarterback over the same time period (Steve Young, 181 touchdown passes), an NFL record for touchdown pass differential.

Favre and the Packers continued posting positive results through the next few seasons.
