We made a few UI enhancements and fixed several reported bugs in this release. As usual we have also created more automated tests to ensure stability and avoid regressions.


Show/hide Command Editor

Another change we have introduced in Firebug 2 is related to the way how the Command Editor (aka multiline command line) is opened and closed.

The Command Editor (together with the Command Line) is one of the most useful features for development. It allows the execution of JavaScript code snippets, as well as calling existing functions on the page or defining new ones.

The script is executed in the context of the current page and if the debugger is currently halted (e.g. at a breakpoint), the script is executed in the current debugging frame. So for example you can also use local variables available in the current frame scope in your script.

The following screenshot shows how the Command Editor looks like when opened in the Console panel.


The Command Editor can be opened/closed using the little arrow button in the top right corner, which is exactly the same way how side panels on other panels are opened/closed. This new approach makes the entire UX more consistent.


See the next screenshot showing how the UI looks like if the Command Editor is closed.


You can use the top-right button to open the Command Editor again, or click the bottom-right red button. We kept the red button in there, since it was in Firebug for a long time and users could miss it. But we’d like to remove it at some point since we believe it isn’t that important anymore. What do you think?


Please post feedback in the newsgroup, thanks.
