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.

Basic Excel Spreadsheet Generation (ASP/ASP.NET)

The 'correct' way to generate Excel spreadsheets is through the use of Office Web Components . However, due to the licensing (see MSKB Article ) you cannot use them on a public internet site (as a client license for Office is needed for each user retrieving the document). However, this can be overcome due to the fact that Excel recognises HTML code. You can therefore output HTML that can be opened in Excel: First of all, set the content type and response header to make the browser handle it as an Excel spreadsheet. ASP VBScript: <%@Language="VBScript"%> <% Response.ContentType="application/vnd.ms-excel" Response.AddHeader "content-disposition", "attachment; filename=ExcelFileName" %> ASP JScript: <%@Language="JScript"%> <% Response.ContentType="application/vnd.ms-excel"; Response.AddHeader("content-disposition", "attachment; filename=ExcelFileName"); %

The HTML Agility Pack is an HTML parser for .NET, supporting XPATH and XSLT parsing. Basically the HTML equivalent of XmlDocument .
