In case you were looking for your Twitter timeline rss feed, you are out of luck. The #newTwitter no longer provide rss feeds of your friends timeline. We confirmed this with Twitter Support, after submitting ticket to them few days ago. We found this after we failed to find rss feed from our own Twitter account within the new interface of Twitter. Earlier back then, Twitter provides their users friends timeline rss feed at the bottom of the page, providing you the latest feed of your friends’ updates. Even if you revert back to the #oldTwitter, it will ask you for authentication, using your Twitter credentials does not apply here since it is for “Twitter API”. So if you are using some hacks that utilize the rss feed, you no longer able to fetch it now. The workaround is to setup OAuth authentication to Twitter API and fetch the streams from there.
However, if you were looking for your “favorite” rss feed, you can find it if you using Firefox browser. Let us know if you have any other workaround for this.
