In SeaMonkey 2.0.3 zijn veel crashes verholpen en andere kleine fouten opgelost die de stabiliteit van het internet pakket van Mozilla moeten vergroten. Ook zijn problemen met de mail-component opgelost en werkt knippen en plakken beter onder Windows.

SeaMonkey 2.0.3 lost ook vijf beveiligingslekken op. Drie daarvan worden als kritiek bestempeld en twee als gemiddeld.
