Retentia от Maximau5

Users can set how long history is kept for specific websites or categories, or choose to remove it immediately. Retentia scans history locally and classifies websites into categories such as social media, news, shopping, and adult content. Uncertain matches are not applied automatically, keeping the user in control.

Key features:
Rules for individual domains or specific URLs.
Set an expiration period or remove matching history immediately.
Local category classification with an offline database.
History scanner, rule simulator, and overview of active rules.
Automatic browser-history cleanup.
Dark mode, password protection, backups, and privacy-safe diagnostics.
No account, cloud processing, tracking, or external data collection.
Firefox v2.3.1 requires Firefox 142 or newer. The Firefox version does not include a shortcut in Firefox’s built-in History page because extensions cannot access that privileged interface; all core features remain available through the popup and Retentia dashboard.
