Ben url çubuğunda geçerli sayfanın url almak için arıyorum

[BookMark Button In Tool Bar] - User Presses it while on a youtube link and sends it to sitename.com/test.php

Imi url sonra gibi bir şey yazdırır

sitename.com/test.php?url=http://www.youtbe.com/whateverwatever

I tried using referrer bur since it's coming from a bookmark link it won't work I also tried the referrer in Javascript but it still won't work
