Due to its excellent support for web standards, multiple platforms, and extensibility, we will be using Mozilla Firefox to look at the web pages we develop. (There are other browsers that could be used as alternatives, including Safari and Opera, but Firefox is the best tool for the requirements of this class, in the opinion of your instructor.)
However, even Firefox needs some customization, mostly through the addition of extensions. Installing extensions is very straightforward, mostly a matter of clicking on a series of “OK” buttons. The most important part is to remember that a restart of the browser is required in order for freshly installed extensions to be used – not merely closing a window. (When you have finished installing the extensions you wish, there is a prompt to restart the browser at the bottom of the Add-ons window.)
The most important extension to install is the Web Developer plugin. It’s also a good idea to install FireBug.
There are additional extensions, not related to web development, that your instructor uses habitually:
- FireFTP
Adds FTP functionality to Firefox – combined with the above extensions, this essentially converts Firefox into a free, open source, integrated web development environment.
- AdBlock Plus
Blocks advertising on most websites.
- FlashBlock
Blocks auto-play for Flash content on websites, and leaves playback up to the user
- ForecastFox
Local weather conditions and forecast at the bottom of the browser window.
- XMarks
Synchronises bookmarks (and, optionally, passwords) between computers (for example, between home, office, and classroom). (Note that XMarks requires registration to use.)
so we don't need the jQuery minimum length anymore:) cool!
