Suspend inactive tabs to save memory. Attach notes so you always remember why a tab was open. Your browser is not a filing cabinet. BrowserShelf makes it one. Most tab suspenders do one thing: freeze tabs you aren't using to reclaim RAM. BrowserShelf does that too, but it solves the real problem. When you come back to a suspended tab two days later and see "google.com/search?q=…", you have no idea why you had it open. BrowserShelf lets you attach a sticky note to any tab before it sleeps, so when it wakes up, you see exactly why it was there. What BrowserShelf Does Automatic suspension BrowserShelf runs silently in the background and suspends any tab that has been inactive for 30 minutes (configurable). When a tab is suspended, it is replaced by a lightweight placeholder page that shows the original site's favicon, title, hostname, your note, and a single "Restore tab" button. No content is discarded, clicking Restore returns you to the original URL instantly. Memory you can feel Each suspended tab saves roughly 50 MB of RAM. The BrowserShelf popup shows you a live estimate of how much memory you have freed, updated every time you open it. Sticky notes for tabs Click the Note button on any tab row in the popup and type a reminder: "read before Monday meeting", "check pricing", "follow up with Alex". The note appears inline under the tab's URL in the popup, and is displayed prominently on the suspended page itself, so it is the first thing you see when you return. Suspend anything, instantly Suspend all — one click suspends every eligible idle tab in the current window at once. Suspend individual tabs — a Suspend button on each idle tab row in the popup. Automatic suspension — the background service worker checks every minute and suspends tabs that have been inactive for longer than your configured timeout. Full control over what never suspends Pin a tab to exempt it permanently. Add domains to the whitelist (mail.google.com, notion.so, and linear.app are whitelisted by default) and they will never be suspended. Turn auto-suspension off entirely with a single toggle in Settings, all your other preferences are preserved. Keyboard shortcut Press Alt+Shift+T (Windows, Linux) or Option+Shift+T (Mac) to open the BrowserShelf popup from anywhere without touching the mouse. The shortcut can be remapped at chrome://extensions/shortcuts.
