LeechBlock NG is a free browser extension for Firefox, Chrome, Edge, and other Chromium-based browsers that blocks time-wasting websites according to user-defined schedules and time limits. It supports up to 30 block sets with wildcards, exceptions, lockdowns, passwords, and keyword-based blocking.
Use cases
- block distracting websites during work hours
- limit social media use to 10 minutes per hour
- lock myself out of time-wasting sites for a set duration
- schedule website blocking for specific days and times
- block pages containing certain keywords or from referring sites
- add friction to my own browsing with a password on settings
When to choose
- you want a free, flexible, self-controlled site blocker for Firefox or Chromium browsers
- you need per-set schedules, time limits, wildcards, and exceptions
- you want to reduce your own procrastination rather than enforce controls on others
When to avoid
- you need parental controls or content filtering for offensive material
- you must prevent the browser from ever connecting to blocked sites (use a HOSTS file or network-level blocker)
- you need blocking enforced by someone other than the user
