Keypress & AutoComplete in Firefox

If you have a javascript console open while using the firefox browser you'll notice this error from time to time.

Error: [Exception... "'Permission denied to get property XULElement..."

It doesn't cause any problems with the site other then the error popping up and guess works fine in IE. Why? So i searched around and I think it might be an autocomplete/keypress bug in firefox. Just add the attribute "autocomplete=off" to any input that you catch keypress event on.

<input type="text" autocomplete="off" name="BadPopcornIsBetterThenYou" />

The only reason I fixed the error was because I really like using the JavaScirpt Console in firefox. It is quite annoying when this error pops up every like a million times. So yea, fyi for you.
