Error: Permission denied to set property XULElement.selectedIndex Source File

I struggled with this error for half a day ....and finally found a simple fix.

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

This is apparently a bug in FireFox's AutoComplete code. I found a reference to this in Bugzilla, and was able to avoid it like this:

<input type="text" autocomplete="off" name="fname"> etc.

The error message went away and all is well. It did not seem to have any problems in IE before or after adding the autocomplete parameter.

'hope this helps.
