Christian Heilmann’s presentation from FullFrontal 2009.
How do we keep JavaScript safe when browsers don’t really distinguish between different sources and give them all the same rights? Why do we still judge the usefulness of JavaScript by how badly browsers speak it? Learn about some environments you can use JavaScript in securely and marvel at the magic and annoyances that are technologies that try to put a lock on the issue of JavaScript security.

Do you remember how frustrating it can be trying to track down that missing semicolon or misplaced closing bracket? You probably already know this, but sometimes the difference between minutes and hours lost can be the quality of tools available to you. According to John J. Barton, if you’re programming dynamic web pages with Javascript and are using Firefox as your browser, then you definitely want Firebug in your toolbox.
Firebug is an open source add-on that integrates with Firefox to put a wealth of web development tools at your fingertips while you browse. Using Firebug, you can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page.
In this short tutorial, Barton explains how to use Firebug’s JavaScript profiler to measure the performance of a web page. With performance information available, he then illustrates how to use Firebug to identify performance bottlenecks. To conclude the tutorial, Barton uses Firebug to demonstrate the performance improvements gained from the changes made using Firebug.

Jeremy Keith from Clearleft discusses his session at 2008’s UI13 conference called Ajax Design Considerations that Tim attended. What do UX professionals need to know about Ajax to best make use of it in websites and web applications? And why is Jeremy’s title at Clearleft currently "Lineman for the County"?
We’re doing so darn much with the Web platform these days, from cross-domain access mechanisms to new drawing and graphics tools. But in the end, we still have to deal with different web browsers. This discussion brings the leads from Mozilla (Firefox), Microsoft (IE), Google (Chrome) and Opera (Opera) together for yet another incendiary discussion about the future of the web.
Skip to the end if you you want to hear the good stuff.
