Mana bombs are powerful explosive devices developed by the blood elves for use against enemy spellcasters. The exact workings are unclear, but it appears to utilize some kind of massive mana burn that kills its intended targets almost instantly.
This section concerns content exclusive to The Burning Crusade.
The first mana bombs were discovered in Outland, used by blood elves loyal to their Prince, Kael'thas Sunstrider. Kael'thas utilized these vile weapons to remove what he perceives as "obstacles". He has used this weapon twice: a Broken draenei from Tuurem suicide-bombing the Cenarion Thicket in Terokkar Forest, and bombing Kirin'Var Village in Netherstorm. A third is prepared in the courtyard of Firewing Point, the closest of Kael'thas' outposts to Shattrath City, for use against either the Allerian Stronghold or Stonebreaker Hold, near the edge of the Bone Wastes or possibly Shattrath itself.
After a series of quests investigating what happened to Cenarion Thicket and discovering the blood elves' complicity, adventurers from both sides are tasked to attack Firewing Hold and set off the bomb before it can be used. The final code to set off the bomb is held by a blood knight named Sharth Voldoun, who resides at the top of the tower high above the courtyard.
Tides of War
The Horde eventually created a mana bomb of their own, its destructive power augmented by the Focusing Iris, which had been stolen from the Blue dragonflight. By crushing Northwatch Hold and making a brazen display of his superior numbers, Garrosh Hellscream goaded the Alliance into moving many of their strongest members — including General Marcus Jonathan, Rhonin and a portion of the 7th Legion — into Theramore Isle to defend against the inevitable attack. The mana bomb was then dropped from a zeppelin, completely obliterating the city and everyone in it. Because of the use of the Focusing Iris, the mana bomb was so powerful that it tore holes in the fabric of reality, and magically altered the physical structure of those caught in the blast.

As the apparent mechanics of mana bombs and the known mechanics of Arcane Bombs (which are crafted by Engineers) are somewhat similar, it could mean Mana Bombs are an extremely powerful variant of Arcane Bombs.
