MarkBridge – Multi-Profile Sync

Sync your bookmarks and extensions across all Chromium-based browsers via GitHub Gist or Google Drive.

Tired of manually exporting and importing bookmarks between browsers? If you use multiple Chromium-based browsers, you know the pain — your bookmarks are stuck in each one with no way to keep them in sync. Google's built-in sync only works within Chrome. MarkBridge fixes that. WHAT IT DOES MarkBridge keeps your bookmarks and extensions in sync across every Chromium-based browser, automatically. Install it on each browser, connect once, and forget about it. No more exporting JSON files. No more "which browser had that bookmark?" No more lost links. HOW IT WORKS • Install MarkBridge on each browser you use • Connect your GitHub token or sign in with Google • Your bookmarks and extensions sync automatically in the background — done YOUR DATA, YOUR STORAGE MarkBridge doesn't use any third-party server. Your data is stored in: • A private GitHub Gist (free, just needs a token with gist scope), or • Your Google Drive's hidden app folder (only this extension can access it) Your credentials never leave your browser's local storage. FEATURES • Works across all Chromium-based browsers • Auto-sync every 1–60 minutes (you pick the interval) • Multi-profile: each browser is auto-detected and gets its own profile • Extension sync: see which extensions are installed on your other browsers and install missing ones from the Web Store • Switch profiles: change your active profile and sync bookmarks with one click • Push (force upload) and Pull (force download) when you need control • Version tracking prevents older bookmarks from overwriting newer ones • Redesigned settings with two-column layout, custom profile dropdown, and confirmation modals • Clean dark UI with tabbed popup and real-time sync log WHAT'S NEW IN v2.0.0 • Extension sync — your installed extensions are backed up alongside bookmarks. See what's installed on each browser and install missing ones directly from the Web Store. • Google Drive login fix — resolved OAuth redirect URI issues for smoother sign-in. • Redesigned settings page — two-column layout with grouped cards, custom profile dropdown with "Create new" option, and unsaved changes detection. • Tabbed popup — new Extensions tab in the popup shows your extensions with install status across all synced profiles. • Switch profiles — switch your active profile directly from the settings page with a single click. • Delete profiles — remove old profiles and their data from the sync backend. • Faster loading — parallel file fetching for Google Drive makes profiles and extensions load significantly faster. • Smarter extension filtering — browser built-in extensions are automatically excluded from sync.
