Features & Capabilities

BlockSite Chrome Extension

BlockSite is a powerful Chrome extension designed to help you stay focused, improve productivity, and control your internet usage by blocking distracting or harmful websites. Easily create custom block lists or use the bulk adult content blocker to protect yourself and your family from inappropriate sites. Use keyword-based blocking to filter out unwanted search results and websites. Set specific times for blocks to activate, ensuring that your focus remains during work or study hours. Switch between blacklists and whitelists for flexible control over your browsing experience. Easily access the quick block feature with a right-click, and redirect blocked sites to safer alternatives to build a more positive and effective online environment.

Privacy is important; BlockSite collects some usage data anonymously and allows opting out of data collection. It’s an ideal tool for parents, students, or anyone looking to reduce procrastination and stay productive online.

User Reviews

Reviewers repeatedly note that BlockSite helps block hateful/annoying sites to boost focus, but the core drawbacks are a clunky, non-intuitive UI and blocking delays or reliability issues, including pages loading before blocks and occasional non-functionality.

Pros

Blocks hateful and annoying websites, helping improve work focus.

Cons

Poor UX/UI: hard to start using; blocking flow requires extra steps and shows separate screens.
Blocking is not immediate or reliable: pages may load before BlockSite blocks, and some blocks may not apply consistently.

Is BlockSite 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.

BlockSite requires a lot of sensitive permissions. Exercise caution before installing.

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.

BlockSite has earned a fairly good reputation and likely can be trusted.
