Console² for Firefox
Console²
replaces the JavaScript Console with what could be the
next generation Error Console.
As of Firefox
1.5, the JavaScript Console is used not only for
JavaScript errors, but for CSS errors as well. This
extension takes this into account by providing a simple
possibility to display errors by type.
Console²
let's you display errors filtered by type (Errors,
Warnings, Messages), language (JavaScript, CSS, XML) and
context (Chrome, Content). Furthermore it provides a
simple search box (as seen in the History and Bookmarks
sidebars), hiding of duplicates, sidebar optimizations, a
customizable toolbar and some more accessibility
improvements.
