What kind of element do you mean?

Can you post a link to a (test) page with that code or the code that is used?

In IE source for ‘Add Doc Set’ button -

<input type="submit" name="method" value="Add Doc Set" class="button" id="Add_Doc_Set">

In Firefox – source is

<input type="submit" name="method" value="Add Doc Set" disabled="disabled" class="button" id="Add_Doc_Set">

Is there any script running on that page that might cause it?

Does it also happen if you run Firefox in Save mode ?

I ran it in safe mode and it now works - why is this?

I disabled all add-ons - s/w ran in firefox. I enabled selenium add-on and s/w ran here also.

Thanks for the help.
