Description

User-Agent:       Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; CMDTDF; InfoPath.2; .NET4.0C)

when firefox encounters a single html comment line, it block comments all the subsequent html code untill the next single comment.

like 

<!--my comment -->

    <div>                        }
        <p>......</p>            } <--- Ignored or block commented by firefox
    </div>                       } 

<!-- my next comment -->

Reproducible: Always

Steps to Reproduce:
1.Add single line html comment line between any html code.
2.Add another anywhere after it
3.
Actual Results:  
The html code between the single comment lines are block commented out

Expected Results:  
firefox should only comment the code that is between
<!--  -->

the workaround that i use for this is

<!--------------->
<!--my comment -->
<!--------------->


    <div>                      }
        <p>......</p>          } <--- Not Ignored or block commented by firefox
    </div>                     }

This is expected see http://www.w3.org/TR/html401/intro/sgmltut.html#idx-HTML for rules on parsing comments.
