Second Bookmark Bar

Second Bookmark Bar is a Chrome extension that displays bookmarks from user-selected folders as a compact secondary bookmark bar on normal web pages.

Last updated: March 7, 2026 Local-first extension No remote code

Summary

Second Bookmark Bar reads bookmark data and extension settings so it can render the bookmark bar, allow folder switching, show optional bookmark utilities, and keep the UI in sync with bookmark changes.

The extension does not send bookmark content, settings, browsing data, or analytics to the developer.

Data the extension accesses

  • Chrome bookmark folders and bookmark items selected or used by the user
  • Bookmark titles, folder titles, bookmark URLs, and folder structure
  • Extension settings stored in chrome.storage.sync
  • Local extension state stored in chrome.storage.local, including bookmark refresh state and local usage counters for optional recently used and most used features
  • The URL of the current page when user-facing features such as quick save require it
  • Page URLs needed for Chrome’s built-in _favicon mechanism when bookmark favicons are enabled

How the extension uses data

The extension uses data only to provide visible user-facing features, including:

  • Showing the selected bookmark folder as a secondary bar
  • Switching between configured bookmark folders
  • Rendering bookmark folders, nested menus, and bookmark labels
  • Enabling optional search across bookmarks
  • Enabling optional recently used and most used sections based on local usage history
  • Enabling optional quick save of the current page
  • Letting the user rename or update bookmarks from the extension UI
  • Refreshing the UI after bookmark changes
  • Displaying site favicons through Chrome’s built-in favicon service when enabled
  • Applying adaptive domain rules, excluded-site rules, and quick-hide behavior

How data is stored

Chrome sync storage

Preferences are stored in chrome.storage.sync, such as visibility, language, theme, text size, folder selections, excluded sites, adaptive domain rules, quick-hide preferences, and optional feature toggles.

Chrome local storage

Local operational state is stored in chrome.storage.local, such as bookmark revision data and local bookmark usage counters.

Bookmark usage counters are used only for optional local features and are not transmitted to the developer or to third parties.

Data sharing

Second Bookmark Bar does not sell, transfer, or disclose user data to the developer, advertisers, data brokers, analytics providers, or other third parties.

The extension does not use external analytics, remote telemetry, advertising SDKs, tracking pixels, or remote code.

The extension may cause Chrome to request site icons through Chrome’s built-in favicon mechanism when favicon display is enabled. That behavior is part of rendering bookmark icons in the browser and is not used by the developer to collect or monetize user data.

Web browsing activity

The extension runs on normal web pages because the bar is rendered inside the page context. Its access to page URLs is limited to user-facing features such as:

  • Showing the secondary bar on the current page
  • Optionally saving the current page as a bookmark
  • Applying adaptive domain rules or excluded-site rules based on the hostname
  • Requesting a favicon for bookmark display through Chrome’s built-in favicon flow

The extension does not profile browsing behavior, build browsing histories for the developer, or use browsing activity for advertising or unrelated purposes.

User controls

  • Turn the bar on or off
  • Choose which bookmark folders appear
  • Enable or disable optional tools such as search, recent items, most used items, quick save, favicons, and scroll arrows
  • Edit or remove bookmark folders and bookmark items through Chrome or the extension UI
  • Configure excluded sites and adaptive domain rules
  • Export and import settings
  • Uninstall the extension at any time

Data retention

Extension settings remain in Chrome storage until changed by the user, cleared by Chrome, or removed by uninstalling the extension.

Local usage counters remain in local extension storage until cleared by Chrome, removed by uninstalling the extension, or naturally replaced by newer local usage data.

Security

The extension is designed to keep data local to the user’s browser wherever possible. It does not include remote code loading, external telemetry pipelines, or developer-side data collection services.
