Crumbles clears out the sites you've stopped using and protects the ones you still visit, so you can tidy up your browser crumbs without wiping everything.
Only sites you haven't opened within your retention window get cleaned, so your active logins and history stay put.
What you get
Selective cleanup: only stale sites are touched, recent ones are always kept
Runs automatically on startup and once a day
Adjustable retention window, "active visit" threshold, and a per-site keep-list
Choose what to clear: history, cookies, local storage, IndexedDB, cache
