Need help on w3c standards in firefox to see the flash objects

Hello friends,

I have a peculiar problem in making a site in to W3C compliant. When we insert a flash object in a site the following code appears

<param name="movie" value="images/main.swf">
<param name="quality" value="high">
<embed src="images/main.swf" quality="high" pluginspage="(URL address blocked: See forum rules)" type="application/x-shockwave-flash" width="613" height="133"></embed></object>

when i have checked the using W3c Validator it has shown there is an error in the below code
" <embed src="images/main.swf" quality="high" pluginspage="(URL address blocked: See forum rules)" type="application/x-shockwave-flash" width="613" height="133"></embed></object> "
and this needs to be corrected to make the page w3c compliant. SO i have removed the fllowing part (code) from the above content.
" </object> "

The final code is like this ....
"
<param name="movie" value="images/main.swf">
<param name="quality" value="high">
</object>
"
so far this is fine and woking in IE 6 with out any errors when checked with W3C validator. Now the problem is that i am not able to see the flass objects in firefox. Can you please tell me what to do to see the flash objects on Firefox.
