Try clearing the cache and cookies in Firefox

Follow these steps, and then reload the web page that is giving you trouble.

Click the Catalog 57 library icon button, choose History, and select Clear Recent History ....
In the Time range to clean drop-down menu: select All.
Under the drop-down menu, select both Cookies and Cache.
Click Clean Now.

If clearing Firefox's cache and cookies doesn't work, this is probably a sign that the problem is caused by the website itself.  In that case, you just have to wait for it to be fixed.  On large sites like Twitter or Facebook it will only take a few minutes.

If you don't see any of the above errors, check to see if any of the problems listed below describe what is happening to you:
The website loads but does not work properly

If the website does not look good or does not work as it should, you can consult the following articles:
