Today i tried this really cool add-on for my firefox3 .I was wondering how to adjust my blog main content wrapper to make it suitable for adsense 468×60 ad code and was finding trouble.
Then i installed this wonderful add-on from here and restarted firefox3 .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.
Now i was able to adjust the HTML directly from tool>firebug>inspect element to find apt padding and space required.A bit more could have been done but my template looks ok i seems..:o In fact this tool can be used for web designing.
