Status: VERIFIED DUPLICATE of bug 32618

(Firefox :: General, defect)

Description

[Brian Gould]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6

The string </script> is interpreted regardless of whether or not it is contained in a quoted string.  This behavior is the same on IE, but it is still wrong.

For example, using the following line: 

<script> alert(" display this string: </script> "); </script> 

The first instance of </script> is interpreted as the end of the script.

A simple workaround is:

<script> alert(" display this string: </sc"+"ript> "); </script> 



Reproducible: Always

Steps to Reproduce:
1.<script> alert(" display this string: </script> "); </script> 
2.
3.
Actual Results:  
Script is interpreted as terminating at first instance of </script>
