I can't read that page, but it appears to use the Adobe Flash player. Have you noticed any problems with Flash on other sites such as YouTube?

You can check whether you need to update your Flash player plugin here: http://www.mozilla.org/plugincheck/

When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.

1. Clear Firefox's Cache

orange Firefox button or Tools menu > Options > Advanced

On the Network mini-tab > Offline Storage : "Clear Now"

2. If needed, delete the site's cookies here

While viewing a page on the site, right-click and choose View Page Info > Security > "View Cookies"

Then try reloading the page. Does that help?

Nothing helped, I did everything you said but still i can not see the "Watch Live" in my browser.
