Web Developer Resources

The DRX provides an online resource index for Web developers. In the DRX, you can find many different extensions listed for Firefox. The goal is to consolidate the best into one view and demonstrate the diversity. The ones that focus on Web development have been selected.

Some of the extensions listed focus on HTML, CSS, DOM, XHTML, JavaScript, document validity and structure, URI, images, URL, cookies, forms, Metadata and Semantics, content syndication and other valuable topics and resources for Web development. Firefox is a Web browser that has a core design that is clean, secure and fast. Powerful programming interfaces have been added and the capability of the browser is expanded and is only limited by the ingenuity and skill of the numerous talented programmers that develop the extensions.

It used to be that the opensource web browser Firefox and Google are one of the best of friends, that was until Google created their own web browser: Google Chrome. Since then, the relationship between the two has been a bit distanced lately.

Mozilla CEO John Lilly told ComputerWorld in an interview that his organization’s relationship with Google has been at least a little bit strained since the release of Chrome.

“We have a fine and reasonable relationship,” Lilly said. “But I’d be lying if I said that things weren’t more complicated than they used to be.”

The vast majority of Mozilla’s revenue — 88%, or about $60 million/year — comes from its search advertising deal with Google. It’s unlikely that Google would walk away from that, but now that Google has become a competitor, Mozilla isn’t counting on that revenue stream being there forever.

Whether they patch up or not, Google chrome has provided another avenue for web developers to develop new software and program for.

XQuery was made so that there was a way to query data stored in an XML document, much the same way SQL is used to query a database.

XQuery uses simple functions to query a document. An XQuery function looks a little like a javascript function in that it uses parentheses containing an element that is to be the object of the function. With XQuery, the element in parentheses is typically the name of the document or file to be queried.

To find what it is looking for within that file, XQuery narrows its search by using path expressions that look a lot like the path for an ordinary file stored on your computer, with the various subsets of data within the XML file separated by backslashes. The predicate is the final component of an XQuery function. The predicate tells the function exactly what information, data, or range of data within a particular subset is to be extracted and returned to the user.

One of Mozilla’s useful extension is the HTML Validator. It adds HTML inside Mozilla Firefox. The number of errors of the HTML page can be seen of the form of an icon in the status bar when browsing. Details of the errors can also be seen when looking at the HTML source of the page.

Why is there a need to validate HTML? First, validating HTML makes it possible for your site to be listed on search engines. Browsers will also render better and faster. Most of all, broken link and ugly pages caused by poor HTML can drive visitors away.
