Flash Game Maximizer
A new Firefox extension named Flash Game Maximizer is a must-have for any Flash game enthusiast. It lets you toggle between standard and full-screen modes on any game.
You'll find thousands of Flash games all around the Web, most of which are hosted in a pixel-thin window that requires you to resize your browser to view them. This is not a problem with most games, but some do require that you play them in their default window size, and others don't have the option to go full-screen (or at least they're coded that way).
With Flash Game Maximizer, all that changes: just click a button on the taskbar or use the F12 key and the game will expand into a complete browser window. Then the content will be reloaded in the full browser window, and it will resize along with the window (with or without enforced aspect, or scaled to one of the predefined percentages).
It's an interesting tool that allows you to maximize the screen space used by online games, making them seem like real "games." In addition, it also enhances other Flash contents, such as animations and presentations. It can hide the status bar, adjust the screen size and even set different quality parameters.
