Tab Backup

Back up every tab in the current window in one click, and bring them back whenever you need them. Works in Firefox and Chrome (and Brave, Edge and other Chromium browsers).

• Install from Firefox Add-ons
• Install from the Chrome Web Store

Features

• Back up to a file (JSON, Markdown, plain text or HTML bookmarks), to a bookmark folder that your browser syncs to your other devices, or both.
• Restore from any backup with a preview: choose which tabs come back, and tabs that are already open are left out. Rename a bookmark backup to keep it: renamed backups are never deleted automatically.
• Automatic backups (off until you turn them on, per device) save every window's tabs to bookmarks every hour, 6 hours or day, skipping private windows and unchanged tabs, with their own limit.
• Settings for the file format, file name pattern, bookmark folder name and how many bookmark backups to keep.

Available in English, Dutch, French, German, Italian, Japanese, Russian and Turkish. Tab Backup doesn't collect or send any data. See the privacy policy.

Build from source

Requires Node.js 22 or later and pnpm 12.

pnpm install --frozen-lockfile
pnpm build          # Firefox build in dist/
pnpm build:chrome   # Chromium build in dist-chrome/

These steps reproduce the files submitted to the stores. The built folders contain bundled, minified code built by webpack from src/.

• Development and testing
• Releasing a new version
