Web Locker door CosmicZygote

WebLocker hides websites behind a full-page lock screen so they stay private during screen sharing, presentations, or any time someone might see your browser.

If you use the same browser for work and personal browsing, WebLocker lets you keep certain sites out of sight without closing them. Locked pages are covered by a dark overlay, and their tab titles are disguised so nothing is revealed in the tab bar either.

How to use it:

1. Click the WebLocker icon in your toolbar.
2. Add any domain you want to keep private (e.g. youtube.com, reddit.com).
3. When you visit that site, it will be fully covered by a lock screen.
4. Click "Unlock" on the overlay to temporarily reveal the page.
5. The site automatically re-locks after a period of inactivity.

Key features:

• Full-page lock overlay that completely hides page content
• Tab title disguise — locked tabs show a custom title (default: "Locked") so the tab bar doesn't give anything away
• Smart auto-lock timer based on inactivity — active browsing keeps the site unlocked, and the timer only starts when you stop interacting or switch tabs
• Free-time schedule — optionally disable locking during certain hours and days (e.g. evenings and weekends)
• Quick actions from the popup — add, lock, or unlock the current site with one click

100% local and private. WebLocker has no accounts, no servers, and no data collection. All your settings are stored locally in your browser.

Note: This extension is experimental for now.
