What the Firefox 30 prepares for us

The native functions of the Firefox browser shell are increasingly taking on the original functions of Firebug and the Webkit shell. - transl.

Firefox 30 has recently begun to be developed on our release channel Aurora, so take a look at its important changes.

DOM Inspector

One of the most popular features is to view the components of the box-model for page elements. We are pleased to announce that it appeared in Firefox 30. Cool, that the highlight colors of the box model are better than before, the same colors on the same model in the diagram on the right.

View the inspector documentation to learn more about its functionality.

Toolbar

For cmd + alt + k or ctrl + shift + k, a new behavior is set — focusing on the console input line (similar to the typical console behavior on Linux or Windows), opening the panel if necessary, but not closing it. Read more about the changes in the robcee.net blog ( notes ).

To save some space, several settings appeared in the panel for hiding part of the commands. By default, 3 buttons are open. Read more - in the "Tools" mailing list ( notes ). Switching - by clicking in the settings panel.
