Well this is a really weird issue, I really didn't find anything on this elsewhere so I thought I'd address it here.

Say I have an "image.jpg" and accidentally reference it in the CSS like so:

url(imag.jpg)

Note the missing "e". Now for me, Firefox is so incredibly clever that it will still find the correct image, but NOT SPIT OUT A WARNING. So I assume that everything is ok.

But later, when I test the page in any other browser, all of a sudden the image doesn't display (and rightly so). That's because Firefox thought it was a good idea to correct my error without telling me.

This becomes more critical with scripts. Firefox will also auto-correct a typo in a reference.

I just wasted a whole hour scratching my head and trying to debug an ajax function in Webkit - turns out, I just had a typo where I included the file.

Why on earth does Firefox do this without telling, and where the heck can I turn this off? This has first occured somewhere around FF 3.0 and still persists in 3.6.3.

/rant an thank fo any inpu ;)
