Ok, so before you get too excited it’s not really a fully fledged version fantastic Firebug Firefox plugin, but the lite version does go some ways to easing your cross browser development.
If you’re not aware what Firebug is, the official site quote is:
Firebug integrates with Firefox to put a wealth of development tools at your fingertips while you browse. You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page.
But that doesn’t explain just how excellent Firebug is, it is by far and away not only the most complete debugging plugin I have found for any browser, but it also seems to be one of the most complete and professionally executed Firefox plugins around.
I cannot bear to live without it, especially when I am working in JavaScript, so the lite version goes some way to ease the pain when working in other browsers by providing a similar console for dumping information to. Until I found the lite version recently I had a workaround function that either used alerts or my own debug console (which I’m not linking to as I am contemplating dropping from the site) in other browsers to ensure that the code still worked and provided some useful debug information, now I no longer need that work around.
I still long for a real cross browser version of the full Firebug feature set, but I’m pretty sure that would be a lot of work for some of the browsers.
