User Reviews

Overall, Impulse Blocker is praised as a simple, effective site blocker that works for many users: easy to set up, quick to add sites, and helpful for beating procrastination and addictive browsing. However, several reviews note reliability issues or platform limits—especially on Android—and privacy concerns about broad data permissions. Some users also dislike the post-block page, and the pause/disable flow can feel cumbersome, prompting calls for stronger disable controls (e.g., 2FA). Despite these, many users consider it one of the best site-blocking tools available.

Pros

Blocks sites effectively and as advertised.
Simple to set up and easy to add sites.
Helps reduce procrastination and maintain focus.
Reliable and lightweight; no major bugs reported.
Highly regarded by users as a top site-blocker.

Cons

Some users report it does not work at all.
Android version is not supported; not working on Android.
Privacy concerns about permission to read all webpage data, including passwords.
Pause/disable flow can be inconvenient; users want stronger disable controls (e.g., 2FA).
A blocked-page overlay appears after blocking, which some users find annoying.

This is actually GREAT for blocking sites that are redirected to you like temu when you are on apps that open the site as an ad in your browser (like dating apps). Several times I was on dating apps and the temu ad automatically will open the temu website. Well this blocks that. Just add temu domains. Thanks.

Is Impulse Blocker 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.

Impulse Blocker requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

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.

Impulse Blocker is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
