From 2000 until 2003 Þóra attended Duke University, where she studied mathematics and history, and played varsity soccer.

Þóra had already spent the 2004 season in Norway as Bente Nordby's understudy at Kolbotn, when in January 2007 the opportunity to move to Belgium came up through her career outside football.^[3] In August 2007 she left Anderlecht to join sister Ásthildur in Sweden at Malmö, who needed a goalkeeper due to Caroline Jönsson's anterior cruciate ligament injury.^[4]

In 2009 Þóra played for Kolbotn and was named Toppserien Player of the Year. She signed a three-year contract with Malmö in November 2009.^[5] Malmö secured their first Damallsvenskan championship since 1994 in the 2010 season.^[6]

Þóra was named Damallsvenskan goalkeeper of the year in 2012 and 2013 after keeping 14 "clean sheets" as Malmö recaptured the league title from rivals Tyresö FF.^[8] She announced that her final game for Malmö, who became FC Rosengård for 2014, would be against Piteå IF on 2 July 2014. She agreed to join Fylkir of the Úrvalsdeild upon her return to Iceland.^[9]

At UEFA Women's Euro 2009, Þóra played in two matches as Iceland were eliminated in the first round.

National team coach Siggi Eyjólfsson selected Þóra in the Iceland squad for UEFA Women's Euro 2013,^[10] although she was recovering from a hamstring injury.^[11] Guðbjörg Gunnarsdóttir took the goalkeeping position at the final tournament, playing in the three group matches and the 4–0 quarter-final defeat to hosts Sweden.

Iceland beat Norway 2–1 at the 2014 Algarve Cup, as Þóra made her 100th national team appearance.^[12]

Celebrity goldfish Sigurwin, the mascot of the Iceland women's national football team, was released into Þóra's care after UEFA Women's Euro 2013.^[13] Sigurwin came to prominence during the tournament when Ludvig Lindström of Global Happiness Organization (GHO) publicly criticised the players for keeping him in a jar and making jokes about flushing him down the toilet.^[14][15]
