TabLock - Password Tab Locker Kreios מאת

Lock any tab with a password. Auto-lock social sites including posts and pages. Everything re-locks after restart.

Features:
- Lock this tab or lock all tabs from the toolbar popup
- Auto-lock list with Facebook, Instagram, X/Twitter, TikTok and more, plus your own custom domains (subdomains and all paths covered)
- Unlock once per session: scrolling feeds like Reels stays unlocked until restart, inactivity timeout, or manual re-lock
- Inactivity auto re-lock (configurable, 0 to disable)
- Password + recovery key, attempt cooldown against guessing
- 100% local: password stored only as a PBKDF2 hash, no accounts, servers, or analytics

Limitations (by Firefox design): system pages such as about:addons cannot be locked, and disabling the extension in about:addons bypasses it.
