this is a pokey little second hand asus notebook .. two or three years old, using firefox.
(i know nothing about browsers etc)
when i went to u-tube the site informed me that i'm out-dated.
when i played the video on there - there was no sound.
Apart from that, sometimes coz im on an ipad i cant play videos....
However urs did work, cos i listened to it!! So you still can post them.... Did youtube say you needed the latest flash player? If it did im sure you can click on that and download latest xxxxx
Maybe you should load Google Chrome or Internet Explorer instead. One of the brilliant techies on here will tell you what to do if you ask under "computers" tomorrow.
