Focus Site Locker Firefox

Focus Site Locker

Block distracting websites on a schedule you choose. Set weekday and time windows, protect your rules with a password, and keep settings locked while blocks are active.

Features & Capabilities

Focus Site Locker helps you stay on task by blocking selected websites during the times you decide, not all day, every day.

Whether you want to avoid social media during work hours, keep games off-limits on weekdays, or create a quiet evening routine, Focus Site Locker lets you define exactly when each site should be blocked.

HOW IT WORKS

• Add one or more websites (e.g. youtube.com, reddit.com, or *.example.com) • Set time windows for each day of the week • When a lock is active, visiting a blocked site shows a clear block page instead of the site • Outside those hours, sites work normally. Your schedule, your rules.

BUILT FOR REAL FOCUS

• Password-protected settings. Unlock to make changes, then lock again when done. • Tamper-resistant editing. Each lock can only be changed during its scheduled pauses, when it is not actively blocking. • Grouped schedules. Sites that share the same hours and days appear together. • Multiple time windows. Block the same site at different times (e.g. morning and afternoon). • Enable or disable locks individually without deleting them.

SIMPLE SETUP

  1. Click the extension icon to open Settings
  2. Create a password to protect your configuration
  3. Add websites and set your lock schedule
  4. Save. Blocking starts automatically based on your rules.
PRIVACY

Focus Site Locker does not collect, transmit, or sell your data. All settings and passwords are stored locally in your browser. No accounts, no analytics, no cloud sync.

PERMISSIONS

• Storage: save your lock schedules and password locally • Tabs and host access: detect when you visit a blocked website and redirect to the block page

Focus Site Locker is a lightweight tool for anyone who wants structure around their browsing. Not a nanny cam, not a subscription service. Just clear schedules, protected settings, and fewer distractions when you need them most.

Is Focus Site Locker 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.

Focus Site Locker requires some sensitive permissions that could impact your browser and data security. 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.

Focus Site Locker may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
