Firefox tends to cache (store) many files from websites that you have recently visited. One such file that it caches is the style sheet that we use to change the look & feel in the blogs section.
If you hold "Shift" and press the Refresh button in the Firefox browser, it should perform a hard refresh and grab the updated files.
We will trouble-shoot the other problems that are posted above.
