SiteBlocker FAQ — Frequently Asked Questions

SiteBlocker is a Browser extension that helps you block distracting websites, stay focused, and improve productivity by controlling your browsing habits.

Simply add the website URL to your blocklist in the list. Once added, the site will be inaccessible until you remove it from the list or disable the list.

No. SiteBlocker prioritizes your privacy and does not collect or store any personal browsing data.

Yes! SiteBlocker allows you to set specific time periods when certain lists are blocked, helping you stay productive during work or study hours.

‘Yes, SiteBlocker is free. All core features — custom blocklists, scheduling, Focus Mode, whitelist mode, and cross-device sync — are available at no cost. The optional Insights Pro plan ($2.99/month) adds detailed analytics charts, hourly heatmaps, and focus session tracking.’

‘Yes, but you need to enable it manually. Go to your browser Extensions page, find SiteBlocker, and check the "Allow in Incognito" option (Chrome) or "Run in Private Windows" (Firefox).’

SiteBlocker includes all core features for free — custom blocklists, scheduled blocking, Focus Mode with Pomodoro, whitelist mode, and cross-device sync. BlockSite limits free users to 3 blocked sites and charges $39.99 for full access. Freedom costs $8.99/month. SiteBlocker also collects zero browsing data, unlike both competitors.

Focus Mode lets you start on-demand distraction-blocking sessions. Pick a duration (25 minutes, 45 minutes, 1 hour, or custom), choose which blocklists to enforce, and optionally enable Pomodoro breaks. During a focus session, your selected sites are blocked regardless of your schedule settings.

The Pro plan ($2.99/month, $24.99/year, or $49.99 lifetime) adds keyword blocking (block pages containing specific words in URLs, titles, or page content) and a full analytics dashboard — weekly activity charts, top blocked sites, hourly distraction heatmaps, focus session tracking, and cross-device insights sync. Basic stats (total blocks, streak, top 3 sites) are free for everyone.

Keyword blocking (Pro feature) lets you block any page that contains specific words — in the URL, page title, or page content. For example, add "gambling" as a keyword and any page with that word gets blocked automatically, even if the domain is not on your blocklist. URL and title keywords are checked instantly; page content is scanned after the page loads.

SiteBlocker is available on Chrome and Firefox. Your blocklists and settings sync across browsers when you sign in.

Go to the Extensions page, find SiteBlocker, and click "Remove." You can always reinstall it from the Chrome Web Store or Firefox Add-ons.
