You can see that today different web browser like firefox, internet explorer etc but I dislike all browser except Google chrome. Its a very fast speed web browse than others. It is also possible to operate at low speed. The download speed of chrome is amazing, better than many downloader.
It is possible to download video from you tube by using chrome. It do not slow down the performance of your machine. So if you are using other browser then uninstall it and install chrome. its just .
