A Chrome extension that quietly handles the annoying parts of browsing — cookie banners, duplicate tabs, memory bloat, and tab chaos.
Automatically finds and clicks "Reject All" on cookie consent banners before you even see them. No more banner interruptions.
Detects when you have the same URL open in multiple tabs. Choose between:
- Prompt me — shows you the duplicates and lets you decide
- Auto-close — silently closes duplicates as they open
Suspends inactive tabs to free up RAM. Set a threshold (e.g. 30 minutes of inactivity) and let Crumble quietly put idle tabs to sleep. Wake them up instantly by clicking on them.
Groups your open tabs by domain with one click — GitHub tabs together, Google tabs together, etc.
Inspect and delete cookies for the current page directly from the popup. Clear individual cookies or wipe all cookies for the page at once.
