I was more than a little flummoxed when I started getting messages that Firefox 6 was using 100% of the CPU. Eventually I traced it to the Firebug Console, where I'd inadvertently got 'Strict Warnings (Performance Penalty)' checked. The pane is full of the following warning, endlessly repeated: "reference to undefined property fbs.breakpoints[url] [Break On This Error] return fbs.breakpoints[url]; firebu...vice.js (line 3319) <System>" 'Info' shows that the Firebug log capacity has been exceeded by some colossal and ever increasing number. Looks like a bug in Firebug, I thought. I'm using Firebug 1.8.1. Firefox 6, WinXP SP3.
However, for me this is only occurring on one web page (http:// www.holidaymull.co.uk). I'm web-master for this site, so it concerns me very much. The culprit seems to be a vertically scrolling 'News" marquee (Javascript, of course). The marquee has been running for a long time now (periodic update of content, of course, but no changes to the script), but it's only very recently that I've noticed this effect in Firebug. The same happens on my 'localhost' version of the site. There are no break-points set, but there is a 'setTimeOut' call; could that have the same effect ? The CPU overload problem goes away if I disable 'Strict Warnings', of course. I have not been able to produce the same effect on my Win7 laptop. Is it something I can do anything about, or just a feature in Firebug ? Regards, Tim Dawson -- You received this message because you are subscribed to the Google Groups "Firebug" group.
