Firebug - spotting error before page post

OK this is starting to drive me crazy!

I am trying to do some debugging with firebug, except I keep missing the error.

I have set break on all errors. Except that I think some jQuery code causes the page to post reall开发者_开发知识库y quickly after the error-so I can't see it.

So my question is - how do I stop firefox/firebug from posting before I can read this error?

Your firebug's console menu has a button called persist. This button keeps console messages even after your page has changed.

This is precisely the kind of scenario it was created for.
