If you didn't line up for a midnight screening for Star Wars: The Force Awakens and are having to wait a some time before catching the action for yourself, this spoiler blocking Google Chrome extension might just be a life saver.
Aptly named 'Force block', this free extension allows you to scan all pages or add certain websites to a whitelist, as seen with normal extensions. Coming in at a tiny size of 582KiB and seeing a December 15 update that looked at improving pattern matching logic, this simple extension will come into use for many die-hard fans not yet able to experience the mastery of Star Wars for themselves..
If you're looking for an alternative to this heavily-publicized version you can also check out this competing extension, claiming to do exactly the same things. If you're super worried, maybe you can run both!
