I already restarted the browser several times. Is it hopeless?

No. The startup backup is probably gone, but sync archives, other devices and disk backups are all untouched by restarts. Firefox users are in the best position here — its dated snapshots survive many restarts.

Can I recover bookmarks after uninstalling a browser?

Often, yes. Uninstalling usually leaves the profile folder behind. Look for it at the paths in the per-browser guides before reinstalling, because a fresh install can overwrite what's there.

Does browsing history help?

It is a decent fallback when nothing else works. History is stored separately from bookmarks and often survives a bookmark loss, so you can find the important URLs again by searching it — tedious, but better than nothing.

My bookmarks vanished after a browser update. Why?

Usually the browser created a new profile rather than deleting anything. The old profile is generally still on disk beside the new one, so check for numbered profile folders before assuming loss.

Can this site recover them for me?

No, and it couldn't — the tools here run entirely inside your browser and have no access to your disk. Recovery happens on your machine using the steps above. Once you have a file, the tools can clean it up.

Recover deleted bookmarks — what to do first

Close the browser completely, right now, before doing anything else. Every browser keeps a recent backup of your bookmarks, and every browser overwrites that backup shortly after it next starts. Each launch you make while trying to fix things costs you a copy.

The three rules, whatever browser you use

Quit the browser fully. Not just the window — check for background processes on Windows, and use ⌘+Q on a Mac.
Turn off sync before you restore anything. Sync exists to make devices match. Restore a good copy with sync running and it can dutifully overwrite it again with the empty version from the cloud.
Copy backup files somewhere safe before touching them. Drag them to your Desktop first. Then nothing you attempt afterwards can make the situation worse.

How long do I have?

Chrome, Edge, Brave: Until the next launch. Bookmarks.bak is rewritten at startup, so the good copy survives exactly as long as you leave the browser closed.
Firefox: Days to weeks. It keeps several dated snapshots in a bookmarkbackups folder and rotates them slowly.
Safari + iCloud: Around 30 days, through iCloud's bookmark archives — the only route that still works after a deletion has synced everywhere.
Any machine with backups: As far back as your Time Machine, File History or disk backup goes. Slowest route, highest success rate.

Find your browser

Each guide has the exact file paths and the step-by-step restore:

Chrome — rename Bookmarks.bak over Bookmarks. The single most effective recovery on this site, and the most time-sensitive.
Firefox — Manage Bookmarks → Import and Backup → Restore, then pick a date. Note that restoring replaces everything rather than merging.
Safari — iCloud's Data Recovery → Restore Bookmarks, or pull Bookmarks.plist out of Time Machine.
Edge — same Bookmarks.bak trick as Chrome. If you're chasing much older favorites, the Internet Explorer folder at %USERPROFILE%\Favorites is usually still on the disk.

If sync already spread the deletion

Find a device that has been offline since it happened. It still holds the complete set, because it never received the deletion.

Disconnect that device from the network before opening the browser, export a bookmarks.html, and only then reconnect. A phone left in a drawer, a work laptop you haven't opened this week, an old tablet — any of them will do. Once you have the export, the deletion on your other devices stops mattering.

The same logic applies to a device where you simply haven't launched the browser since: its startup backup is still the good one.

After you get them back

Export immediately — Bookmarks → Export in any browser — and put the file somewhere that isn't a browser profile. That single file makes this whole page unnecessary next time; the reasoning is in backing up your bookmarks.

Recovered sets are also usually messy, because a restore often brings back an older copy alongside what you already had. Two tools help: the duplicate finder collapses the copies, and if you restored from a snapshot that predates some of your bookmarks, the merge tool combines the old and new exports into one clean file.
