Firebug is a free and open-sourceweb browser extension for Mozilla Firefox that facilitates the live debugging, editing, and monitoring of any website's CSS, HTML, DOM, XHR, and JavaScript.
Firebug is licensed under the BSD license and was initially written in January 2006 by Joe Hewitt, one of the original Firefox creators. The Firebug Working Group oversees the open source development and extension of Firebug. It has two major implementations: an extension for Mozilla Firefox and a bookmarklet implementation called Firebug Lite which can be used with Google Chrome.
In addition to debugging web pages, Firebug is a useful tool for web security testing and web page performance analysis.
Firebug 2.0 introduced many new features to the Firebug extension including JavaScript syntax highlighting, pretty print for minified JavaScript code, and a DOM Event Inspector to handle all event handlers on a web page. Additionally, users can search for page elements using CSS selectors in the search bar. The debugging tool now allows users to inspect JavaScript expressions as they are evaluated. Moreover, users can inspect values returned from JavaScript functions. It also adds the ability to create new HTML attributes for existing HTML elements.
Firebug may refer to:
Firebug is the name of three DC Comics supervillains.
The Joe Rigger version of Firebug debuted in Batman #318 and was created by Len Wein and Irv Novick.
The Harlan Combs version of Firebug debuted in Gotham Central and was created by Ed Brubaker and Michael Lark.
The unnnamed Firebug debuted in Deadshot Vol. #1 and was created by Christos Gage.
Firebug first appeared in Batman #318 (December 1979). Joe Rigger was a soldier and demolitions expert who returned to Gotham City when his family had been killed in three separate building-related accidents. His sanity slipping, Rigger vowed that those buildings would not kill again. Using his military training and a costume containing tanks of napalm, he became the Firebug and set out to burn all three buildings to the ground. He was defeated by Batman atop the towering Gotham State Building, and believed dead after his tank exploded.
Firebug reappeared some time later, taking on a mission from the Calculator to invade Hero Hotline's HQ, but was disarmed and defeated by the Hotline members.
Firebug was a 1982 computer game by MUSE Software for the Apple II computer. The game was released on cassette tape and on floppy disk. It was written by Silas Warner, whose most famous accomplishment was Castle Wolfenstein.
The player controlled a "firebug", a 3-by-3-pixel square with a tail stretching behind it. The player picked up gas cans—each represented by a single pixel on the screen—and dropped a can by pressing the joystick button. The end of the player's tail glowed white, and ignited any gas can that it came adjacent to, including cans the player had dropped. Once a gas can ignited, it burst into colorful flames, which ignited any walls they touch.
The goal was to burn down the highest possible percentage of the walls on the level, and escape down the stairs to the next level without touching any flames with the body of the firebug. Tail collisions with fire were expected and ignored. As the game progressed, each level featured tighter mazes of walls, increasing the penalty for player mistakes; and the player's tail shortened, causing player-dropped gas cans to explode sooner.
Computer software also called a program or simply software is any set of instructions that directs a computer to perform specific tasks or operations. Computer software consists of computer programs, libraries and related non-executable data (such as online documentation or digital media). Computer software is non-tangible, contrasted with computer hardware, which is the physical component of computers. Computer hardware and software require each other and neither can be realistically used without the other.
At the lowest level, executable code consists of machine language instructions specific to an individual processor—typically a central processing unit (CPU). A machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also (indirectly) cause something to appear on a display of the computer system—a state change which should be visible to the user. The processor carries out the instructions in the order they are provided, unless it is instructed to "jump" to a different instruction, or interrupted.
Software is a 1982 cyberpunk science fiction novel written by Rudy Rucker. It won the first Philip K. Dick Award in 1983. The novel is the first book in Rucker's Ware Tetralogy, and was followed by a sequel, Wetware, in 1988.
Software introduces Cobb Anderson as a retired computer scientist who was once tried for treason for figuring out how to give robots artificial intelligence and free will, creating the race of boppers. By 2020, they have created a complex society on the Moon, where the boppers developed because they depend on super-cooled superconducting circuits. In that year, Anderson is a pheezer — a freaky geezer, Rucker's depiction of elderly Baby Boomers — living in poverty in Florida and terrified because he lacks the money to buy a new artificial heart to replace his failing, secondhand one.
As the story begins, Anderson is approached by a robot duplicate of himself who invites him to the Moon to be given immortality. Meanwhile, the series' other main character, Sta-Hi Mooney the 1st — born Stanley Hilary Mooney Jr. — a 25-year-old cab driver and "brainsurfer", is kidnapped by a gang of serial killers known as the Little Kidders who almost eat his brain. When Anderson and Mooney travel to the Moon together at the boppers' expense, they find that these events are closely related: the "immortality" given to Anderson turns out to be having his mind transferred into software via the same brain-destroying technique used by the Little Kidders.
