Con fuoco means "with fire". It asks for fiery, impetuous energy: bold attacks, driving rhythm, sweeping gestures and usually a loud dynamic. It is nearly always joined to a fast tempo word, as in Allegro con fuoco or Presto con fuoco.

Con fuoco in real music
Chopin's Prelude in B-flat minor, Op. 28 No. 16, is marked Presto con fuoco: a torrent of fast notes over a pounding left hand. The marking is common in Romantic music, especially in finales and stormy passages.
Fire with control
The danger of con fuoco is that "fiery" turns into "frantic". The notes still need to be clear and the rhythm steady. Practice the passage slowly until it is secure, then add speed and energy step by step. Use the arm for the big accents, keep the hand relaxed between them, and pedal carefully so fast runs do not blur.
Related words
Con brio (with spirit) is energetic and bright, but less wild. Agitato (agitated) is restless and nervous. Appassionato (passionate) is intense and emotional. Con fuoco is the most explosive of the group. Fast tempo words often paired with it are allegro and presto.
