Navigating the Internet while trying to avoid spoilers takes skill and practice. And even then, there's a good chance you'll accidentally click a link that drops a big reveal right in front of you before you've had a chance to see it for yourself.

That's why the idea of this Chrome extension posted to Product Hunt, which claims to be a Star Wars spoiler blocker, is so appealing; it quickly scans the page loading in your browser for any mentions of Star Wars-specific terms and promptly covers the page with the movie logo and some wonderfully apt yellow-scroll text. From there, you can decide to navigate away or proceed anyway.

It even has a clever icon:

Did you spot the problems with the concept in that brief description?

It doesn't just block spoilers, but any mention of Star Wars, and in practice that means virtually any news site you navigate to gets blocked. In our cursory test, the blocker decided that CNN.com, The Guardian, Slate and even Mashable all had "potential spoilers," probably because the sites had headlines that merely mentioned the franchise. That's Death Star-level overkill.

Secondly, it doesn't really work. It takes a few seconds for the blocker to engage — which is plenty of time to scan a page and potentially get spoiled by an indiscreet headline. Not exactly Jedi reflexes.

In sum, though we admire jitbit (the developer) for trying here, there is no try — there is either do or do not. And for anyone thinking about installing this extension to prevent spoilers, we have only this advice: do not.
