is this script error somehow related to firebug?

[jeremy...@yahoo.com]

Hello all, I am no kind of programmer, just wondering if anybody
recognizes what this error is.

Script: file:///C:/Program%20Files/Mozilla%20Firefox%203.6%20Beta%204/modules/debug.js:57

or... what it could represent.

I have begun getting this script error. my current version of
firefox is 3.64b but I've gotten this is other versions of firefox,
on another pc about 2 months ago. always on xp. don't know if OS has
any influence here in this. But, this error I got about 2 months
ago, then on this machine was a new install/all was fine, until about
yesterday the day before.
