Code:
$fid= $_GET['f'];
echo $fid;//prints 3
$SQL = "SELECT threadid, thumb, title, stage, status, startdate ,duedate, forumid FROM thread WHERE forumid = '$fid' ";
work fine!
**Code:**
$SQL = "SELECT threadid, thumb, title, stage, status, startdate ,duedate, forumid FROM thread WHERE forumid ='3' ";

What SQL engine are you using? If it's MySQL you can use:
echo mysql_error();
after running the select to see what error you're having
also try echoing the SELECT statement after generating it to make sure no additional whitespace etc is added to $fid
