I just purchased a new HP computer with windows 7. I installed 3.6. which I use as a default and had no trouble until I tried to listen to a webcast from the BMO metals and mining conference. When I clicked on listen to webcast I got a message tha tadditional plug ins were needed to display all the media on the page. I checked my system and was able to hear the test message, but I could not hear the actual webcast. There was a box in the message saying click here to fins needed plug ins. When I clicked on it I got a screen saying no plug ins found. I have windows media player installed. There was a space to click on to test sound system, and I heard to message on the test, but when I tried to hear the actual webcast I got the same plug in needed message. I then tried to listen on Chrome and got the same result. I tried to listen on Explorer and was able to hear the webcast and got no message about plug ins needed. Is this just a case where they won't accommodate firefox, or is there a plug in or add on that I can install so I can use firefox.
