A Firefox add-on that helps you play the classical Minesweeper game
Version: 1.0Mines is the classic game of Minesweeper recreated for Firefox. Includes several interesting variations, such as games with hexagonal rather than square tiles, games with multiple mines in some tiles, and an option to have the edge of the grid be free of mines (reducing the likelihood of you needing to make guesses).
Operating System: Mac OS X
Once installed, Mines can be accessed from Tools-->Mines.
