Firebug 'Console' filling with 'Strict' warnings

[ramasaig]

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 ?

If you install the Developer Toolbar, you can disable the strict
Javascript messages.

Thank you. Yes, I'd done that, and of course all the warning messages
stopped.
However the nature of the warnings seemed to indicate a problem with
Firebug, not my script, so I thought I should report it.
