LeechBlock

A flexible and powerful add-on for controlling access to distracting websites.

Feature Overview

LeechBlock is a productivity-focused browser extension developed to help users control or limit access to websites that may distract from work or study. Designed especially for Firefox, it offers a comprehensive toolset for customizing website restrictions, making it highly adaptable for different needs—from reducing personal distractions to creating a more focused working environment.

Customizable Blocking Options

LeechBlock stands out for its high degree of customization. Users can create multiple block sets, each with its own list of sites and unique blocking rules. Block access according to a daily schedule, set time limits for browsing certain sites, or combine both methods. For instance, restrict social media to 10 minutes per hour during work hours or block news sites altogether in the morning. This granular control allows users to tailor the extension to their own patterns and routines.

Password Protection and Delays

To help reinforce self-control, LeechBlock offers the option to set up a password or impose a configurable delay before gaining access to blocked sites. This feature serves as a strong impulse check, requiring users to think twice before overriding their own restrictions. However, since the password is user-chosen, determined users could bypass this, meaning it is not recommended as a parental control tool.

Usage Tracking and Feedback

LeechBlock doesn’t just block sites—it also tracks time spent attempting to access restricted domains. The extension provides summaries and usage stats, which can raise awareness about browsing habits and inform future adjustments. A warning message can be displayed before access is denied, serving as an additional reminder when reaching for a distraction.

Usability and Integration

Adding or removing websites from block lists is straightforward through the extension’s options menu. The updated options dialog uses less screen space and is more intuitive, making setup and ongoing management less cumbersome. Links to practical examples and a clear interface lower the learning curve, making it accessible even for users new to productivity tools.

Performance and Compatibility

LeechBlock operates with minimal resource usage and does not noticeably affect browsing speed. Its functionality is built to work with Firefox, and while some versions or forks may support other browsers, the core experience is tailored for Firefox users on Windows.

Recent Improvements

Recent updates have added useful options such as passing blocked URLs for easier troubleshooting, retaining blocked sites in browser history for navigation convenience, and more accurate time tracking, even on pages relying on Flash or Java. The streamlined interface further improves the user experience.
