About this extension
Features
  • Block list — in one place, either block a site completely or give it a daily time
    limit    . Supports bare domains (youtube.com, also matches subdomains), wildcards
    (*.reddit.com), and path prefixes (reddit.com/r/all).
  • Daily time limits — give a site a daily budget (e.g. 30 min) right from the block list.
    Zenblock tracks active usage with a live status bar, and once the budget is spent the site is
    blocked for the rest of the day (resets at midnight).
  • Categories — flip a single switch to block a curated group of sites: Social Media, Video
    & Streaming, News, Gaming, Shopping, or Adult. Add or remove sites per category.
  • Schedule — choose "Always on" or "Only on schedule", and define day + time windows
    (overnight windows supported).
  • Zen mode — a time-boxed lockdown with its own block list and categories, edited
    separately from your everyday lists (Settings → Zen). Optionally also include your main
    block list/categories with a toggle. Begin a session with a duration; while it runs, the
    in-scope sites are blocked even if the master switch is off, and every settings control is
    locked. Changing anything or stopping early requires retyping a ~100-word passage, which grants
    a 2-minute editing window before it re-locks. (It's a strong willpower lock, not tamper-proof
    — see the note below.)
  • Block in private windows — toggle straight from the toolbar popup to enable the blocking in close private/incognito windows too.
  • Custom block page — a calm, on-brand page with your own message, or optionally redirect
    blocked visits to a URL of your choice.
  • Quick controls — toolbar popup with a master switch, mode toggle, one-click "Block this
    site", live time-limit status, the private-windows switch, zen mode (top-right), and a daily
    blocked-attempts counter.
  • Light / dark / system theme, and everything is stored locally (no account, no tracking).
