hi, We send any file by the form with ENCTYPE="multipart/form-data" and method="POST" when file upload successful try refresh page (F5 or refresh button). steps: 1) upload file by form 2) refresh page 3) firefox crash example code: <form action="" ENCTYPE="multipart/form-data" method="POST"> file name:<input type="file" name="filee"> <input type="submit"> </form> P.S. it works with html and php code. -- reyw//[HTB Team]
