NicoruCountFix is a Chrome add-on developed by takusan23. It falls under the category of Browsers and belongs to the subcategory of Add-ons & Tools. This add-on addresses the issue of incorrect display of Nicoru counts on the popular Japanese video-sharing website, Nico Nico Douga.

The problem with the original display is that when a user receives more than 9 Nicorus (equivalent to likes or thumbs-up), the count is shown as "9+" instead of the actual number. NicoruCountFix fixes this by accurately displaying the correct number of Nicorus received. For example, if a video has been Nicoru'd 300 times, NicoruCountFix will display the number "300" instead of "9+".

This add-on provides a simple solution to the inconvenience caused by the inaccurate display of Nicoru counts. Users can now easily see the exact number of Nicorus they have received, allowing for a more precise understanding of the popularity of their videos or comments.
