i tried to write a script which can be added as an extension to the browser. The problem with this script is how to access the dom elements of a webpage. i used XMLHttpRequest object for accessing the web page but it has same origin policy issues. I worked on it for nearly 3 weeks finally i used Anyorigin.com code but i am not able to get all the functionality so i thought of using userscript where we can easily access the web page's DOM elements. Is ther any other way to create an extension

Try this:

Greasemonkey: Customize the way a web page displays or behaves, by using small bits of JavaScript.

Update:

This looks to be a better solution, but I haven't tested it.

  • I even tried converting userscript to firefox extension using [Userscript Complier](https://arantius.com/misc/greasemonkey/script-compiler.php) but it didn't work – user1335906 Apr 18 '12 at 04:41

While enloz's answers are good, Firefox has an Add-on Builder that you can you use.

Add-ons are built using HTML, CSS and JavaScript. There is a web based version with the following features (quoting from their website):

  • Edit code in a feature-rich environment
  • Test your add-ons instantly
  • Use built-in version control & sharing

You can find the web based version here: https://builder.addons.mozilla.org/
