Five singles in total were released from the album. The lead single, "Mississippi Girl", marked Hill's ninth and final country number one hit and her first since 2000's "The Way You Love Me"'; it spent two weeks atop the Hot Country Songs chart. Follow-up singles "Like We Never Loved at All", "The Lucky One", and "Sunshine and Summertime" (which was her last solo top ten hit at country radio) all peaked within the top ten, with the first two peaking within the top five. "Stealing Kisses" was also a top 40 hit.
In its first week, Fireflies debuted atop both the all-genre Billboard 200 and Top Country Albums, selling 329,000 copies. Fireflies marked Hill's third consecutive album to top both of the charts simultaneously after 1999's Breathe and 2002's Cry. The album has been certified two times platinum by the RIAA for selling two million copies. Despite the commercial success, it was met with mixed reviews with many complaining that the album was bland. "Like We Never Loved at All" won the Grammy for Best Country Collaboration at the 48th Grammy Awards in 2006 while "Mississippi Girl" and Fireflies were nominated for Best Female Country Vocal Performance and Best Country Album.
