World Cup Hater is a Chrome extension developed by NiLord that allows you to hide all football-related posts from your Facebook timeline. This free extension is categorized under Browsers and falls under the subcategory of Add-ons & Tools.

With World Cup Hater, you can easily filter out any posts related to football and the FIFA World Cup 2014 in Brazil. The extension uses keyword searches to identify and hide these posts from your timeline on Facebook.

[UPDATE]

In the latest version, 1.0.4 BETA, a critical bug has been fixed. Additionally, instead of completely hiding the football posts, World Cup Hater now replaces them with images of cats. However, if you access the post through a direct link, you will still be able to view the entire post.

Please note that this extension may block posts that contain any of the keywords, which could potentially hide posts unrelated to the World Cup. It may also allow some posts with expressions that are not considered football-related. While it may not eliminate all football-related posts, it significantly reduces their visibility on your timeline.

Please be aware that World Cup Hater is currently only available in Spanish, but an English version is in development.
