Firefox Extensions for Web Developers

One of the best features of Firefox is that it can easily be improved by using extensions. Talked about it before in February - Firefox Extensions (for Firefox 0.8). No developer extensions (that I can find) since then (new features added to existing ones, updated due to version changes, added to Mozilla Update), but that may simply be because the current ones do what most developers want. Here are the useful ones to web developers:

  • Web Developer Extension, by Chris Pederick, the best one so far
  • IE View - for those rare times when you need to open a page in Internet Explorer, or for testing purposes
  • LiveHTTPHeaders - for viewing HTTP Headers you send/receive to/from websites
  • EditCSS - editing CSS live on a website in your side bar (you can do this with the Web Developer Extension as well).
  • User Agent Switcher, also by Chris Pederick. To make some sites think you are using a different browser.
  • JavaScript Debugger, AKA Venkman - for debugging JavaScript errors.
  • Web Panel Enhancer - allows you to do various things in the sidebar, like open link, current page, or show source code

There is also a tutorial available on creating extensions for Firefox.

iTextSharp: Generating a Basic PDF file (ASP.NET/C#)

iTextSharp is free library for .NET that allows you to create PDF documents. It can be used to dynamically create PDF's which can be streamed to the user. As there is no HTML being sent to the user, a WebHandler (ashx file) is a more appropriate way to generate your PDF than an aspx page. Download itextsharp-3.0.10-dll.zip (latest version as of 08 Feb 2006) and save the dll in the archive to your websites bin directory. Here is a basic sample of creating a PDF (more complex samples may follow in future posts). BasicPDF.ashx <%@ WebHandler Language="C#" Class="MyNamespace.BasicPDF" %> using System; using System.IO; using System.Web; using iTextSharp.text; using iTextSharp.text.pdf; namespace MyNamespace { public class BasicPDF: IHttpHandler { public bool IsReusable { get { return true; } } /// <summary> /// Font used for any hyperlinks added to the PDF /// </summary> private Font LinkFont { get

Popup Window Countdown (JavaScript)

This code opens a new popup window that contains a timer that counts down, then closes the window when it reaches 0. Will not work if user has a popup blocker blocking the page. <html> <head> <title>Popup Timer</title> <script language="JavaScript" type="text/JavaScript"> // popup window var var popup; // At what number shall the countdown counter start? CounterStart = 10; // This function CustomAction() can be modified to do // whatever you want done every second. function CustomAction() { popup.document.timer.timeleft.value = CounterStart; } // end of function CustomAction() // end of JavaScript customization function Decrement() { CounterStart--; CustomAction(); if(CounterStart <= 0) { popup.close(); alert('Timer reached 0'); } else { setTimeout('Decrement()',1000); } } function StartTheCounter() { openPopup(120,100); setTimeout('Decrement()',1000); } f
