Add-on summary

PuzzleBlocker is a browser extension that helps you spend less time procrastinating and more time being focused. To unlock time-wasting websites – like Facebook, Instagram or Reddit – you have to solve Tangram puzzles.

Solving puzzles takes time and will make your brain think procrastination is actually hard work. At best, you will close the tab and keep working. At worst, you have "earned" the reward of procrastinating for a couple of minutes.

User reviews

This is great. There are some sites I spend too much time on, and this makes me pause a bit before I go to them. Because it's a puzzle, I don't try to work around it. And because it's not a hard puzzle, it gives me time to think about whether I really want to use the site or if it's just habit/procrastination.
