Firebug 1.12 alpha 6 introduces one new feature called simply: Use in Command Line
This feature allows referring various page objects (HTML elements, JS objects, network requests, cookies, etc.) from within Firebug Command Line.
The user can also use object's properties in JS expressions.
See issue 6422 for more details.
This post explains the feature in detail and also asks for feedback.
One of the new features introduced in Firebug 1.12 alpha 5 is a filter for DOM event logs (issue 229).
Logging of DOM events has been available in Firebug for a long time and the filter should make it more useful and effective in daily usage.
The problem is that we are unsure whether UI/UX of the filter is implemented properly.
So, if you are using this handy feature please read further and let us know what you think (leave a comment below).
I had an opportunity to be a reviewer of a new book about Firebug written by Chandan Luthra. This is actually the second book dedicated to Firebug and so, you might also be interested in the first one.
The book is labeled Instant Firebug Starter
Monitor, edit, and debug any web page in real time with this handy practical guide.
Firebug UI is entirely based on XUL/HTML/CSS and so, it's easy to provide a new set of CSS styles (a theme) that modifies Firebug UI and adjust it to your needs and preferences.
One of the typical examples of such modification is changing the background color (dark vs. white).
This post explains how to use Jason Barnabe's Stylish extension and apply arbitrary CSS on Firebug UI.
Thanks to Luís who mentioned this!
Firebug Command Line is probably one of the most important Firebug features and its value is yet extended by set of built-in commands.
One of the new commands, introduced in Firebug 1.11 is
include() and this post is intended to explain how to use it and make your development more effective.
Before we start with include() command let's take a look at quick summary of all Firebug built-in commands.
