ForgottenTabs detects when you're browsing something you've already saved — and surfaces it before it gets lost forever.
How it works
ForgottenTabs runs silently in the background. Every time you open a page, it compares it against your entire bookmark library.
Install the extension and forget about it. It watches every tab you open without any manual input required.
ForgottenTabs compares the current page with your saved bookmarks and calculates a similarity percentage.
A floating panel, badge, or Chrome notification appears — your choice. Open the old bookmark in a new tab, or swap it with the current URL to keep your library fresh.
Features
See exactly how closely the current page matches your saved bookmarks — ranked by relevance, not just URL.
Choose how you want to be alerted: a floating side panel, a badge counter, or a native Chrome notification.
Replace outdated bookmarks with the current page in a single click. Keep your library up to date effortlessly.
Instantly search across all your saved bookmarks from within the extension panel — no more digging through folders.
Browse and save bookmarks by folder structure. Keep everything organized exactly the way you like it.
See an estimated reading time for each bookmarked page so you can prioritize what to read and when.
Automatically find and flag duplicate bookmarks across all your folders — de-clutter in seconds.
Move stale or rarely-visited bookmarks to an archive instead of deleting them. Declutter without losing anything.
Notification modes
A small button sits on the right side of your screen. Click it to expand the full match list.
A counter badge on the Chrome toolbar icon updates silently — clean, minimal, distraction-free.
Get a native system notification whenever a match is found — even if the extension isn't open.
Already saved a YouTube video as a bookmark? ForgottenTabs recognizes it while you browse and brings it back to your attention — so your saved videos finally get watched.
No more forgotten "Watch Later" graveyards. ForgottenTabs bridges the gap between your saved videos and what you're actually watching right now.
