User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

The standard JavaScript parseInt Global method does not work for leading zeros
in string. parseInt("09") returns a 0 not a 9 using Mozilla Firefox.
This issue is also a problem in IE.
The parseInt function does work correctly in the Opera browser.  parseInt("09")
should return a numerical 9 for all browsers.
Problem was discovered in my JavaScript demo program at the following URL:
http://www.islandman.org/_uog/cs201/parseIntBug.html

Reproducible: Always
Steps to Reproduce:
1.Create JavaScript program that uses parseInt with the argument string has a
leading zero such as "0123".
2. Numerical return  value should be 123, but becomes 83
3. For Example see http://www.islandman.org/_uog/cs201/parseIntBug.html

Actual Results:  
Always is a problem

Expected Results:  
parseInt JavaScript function should return a numerical value without the leading
zero. parseInt("0123") should return a numerical value 123

Opera runs this parseInt JavaScript function correctly. IE has same problem as
FireFox.
