Firefox 16 brings developer command line for faster debugging

The newest version of Firefox includes a command line feature designed to make it easier for developers to debug code and assess websites using the browser's tools.

Mozilla has pushed out Firefox 16, updating the program with a new command line feature designed to tempt developers back to the browser.


The updated browser, released for download on Tuesday, is light on new features in comparison with previous versions, but does introduce a new developer toolbar and the command line.

The developer toolbar, when selected, appears at the bottom of the screen and allows quick access to features like the page inspector and debugger.

Alongside the toolbar is the command line interface: this is designed to allow developers to easily run commands for controlling browser tools, such as style sheets or add-ons, using only the keyboard. For example, typing 'open' prompts the autocomplete to offer the options 'console open' and 'tilt open' (pictured above), while typing 'list' gives the options to jump to the add-on list, break list or cookie list.

In addition, Firefox 16 also "unprefixes a number of stable features including: CSS3 Animations, Transitions, Transforms, Image Values, IndexedDB and Values and Units. Firefox also unprefixes Battery API and Vibration API, two web APIs that Mozilla helped create", Mozilla said in a blog post on Tuesday.

A number of bug fixes have been rolled into Firefox 16, but some known bugs, such as one that causes the browser to crash if it's opened using a locked profile, have not been put right.

The mobile version of the browser has been given minor incremental improvements, including the addition of a 'Reader' mode for viewing and sharing articles on an Android phone or tablet. Tapping the 'reader' button in the Awesome Bar activates the tool, which automatically reformats text and pictures, and removes any ads.
