New Xkit is a browser extension designed to work with the tumblr social media website. It provides features that the core website lacks, such as the ability to view the tags on a post and to view all replies to a given post, regardless of date or number. It also provides other features such as blacklisting words rather than just posts. On the other hand, while it is available for most browsers, it is not compatible with more obscure browsers such as Opera, and some features, such as the tag viewing, run slowly under certain configurations.
