Zen Tabs Cleaner od qskkk

Zen Tabs Cleaner brings Arc's auto-archive to Zen Browser and Firefox.

Every 15 minutes, it checks each tab's last activity and closes tabs that meet ALL of these conditions:
• inactive for longer than your threshold (12 hours by default) — each tab has its own countdown, reset
every time you visit it
• not pinned (pinned tabs and Zen Essentials are never touched)
• not the active tab of a window
• not playing audio (music, video calls…)
• not on a domain from your exclusion list

Tabs hidden in other Zen workspaces are cleaned too, just like Arc's spaces.

After each cleanup, a notification tells you how many tabs were closed — click it to restore them all. You
can also restore from the popup.

Extras:
• "Clean now" button in the popup to close all unpinned tabs on demand
• Pause toggle to suspend cleaning temporarily
• Configurable threshold with 1h / 6h / 12h / 24h presets (decimals accepted)
• Domain exclusion list (subdomains included)
