make sure javasript is enabled.

type about:config in address bar, and press enter, accept any warning, Then type in to the page's search bar va.en and highlight the pref by right clicking and toggle to true if necessary.

or,

In the address bar, type about:config , and press Enter. accept the warning, In the search bar, search for javascript.enabled, Right click the result named javascript.enabled and click "Toggle". JavaScript is now disabled. To Re-enable JavaScript, repeat these steps
