This is a Chrome Extension to quickly and easily block all mentions of the new Avengers movie until you've had a chance to go and see it. There are spoilers everywhere - beware!
I made this today after seeing numerous articles on how to best avoid Avengers spoilers. Also, Avengers spoilers were trending on Twitter. Enjoy!
Spoilers Blocker allows you to define keywords, and when a text containing one is detected in a protected app, it gets covered (you can long click the cover to reveal the text)
