People (mostly us!) have been having a problem with Firefox blocking the Twitter feed on various websites (OURS!) that aren't "Twitter". We ran into a similar problem ourselves. This has to do with the tracking protection feature that's been updated on Firefox. It took some digging but we've figured out how to re-enable the twitter feed if you're using Firefox and have Tracking Protection enabled. You can either take this to heart, or not but we're not tracking you, so please feel free to disable Tracking Protection from this site.
