Warning: Empty string passed to getElementById().
Source File: chrome://browser/content/browser.xul
Line: 0
Some days ago I started getting the above message while developing my site. Things are working as they should (or at least I think they are), but I want to find out where this is coming from. I use jQuery so do not use getElementById() directly. Plus I have Firebug and the Web Developer extension for Firefox running.
I could laboriously put in code to check for an empty string being given to a jQuery selection or maybe look into jQuery itself, but my skills are minimal, so I’m asking here if anyone has offhand a good idea for quickly locating the source of the warning messages.
This means that the error is in a Firefox extension, not in your code.
