Firebug throwing excessive script errors during normal browsing

Question

I expect this might get some downvotes / closevotes but I'm going to ask anyway as I can't find an answer to this anywhere else, and I know that others who use Firebug on a daily basis must have noticed this too.

When I hit many "big" sites, such as Google, Paypal, Wordpress sites (especially the admin interface after a couple of plugins are active) and others with Firebug active, it can break on atleast 2-3 errors per page request. Normally it's undefined variables or something along those lines, quite often in jQuery (although what caused that error isn't).

This is very annoying >:( and much more frequent than I remember even a year ago. It happens alot on websites that you would expect to be well checked for script errors which is what I find to be the most puzzling - whenever Firebug reports an error on one of my sites, I fix it until none show up, ever. What's the difference here?

What I want to know is this: has firebug's error detection gotten alot stricter recently or have the general standards of script coding gotten worse - or a mix of both?

Or am I just being an idiot and have switched on super-uber-mega-strict error checking somehow?

Using Firebug 1.9.1 with Firefox 11.0 on Max OSX Lion.

the kind of thing I see more times a day than I should in a month:

ps error is a is null , somewhere in the jQuery source.
