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.

Is PuzzleBlocker Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
PuzzleBlocker requires very minimum permissions.
Risk impact analysis details
- High Allows retrieval of a user’s browsing history, presenting a notable privacy risk.
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
PuzzleBlocker is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
