ContainMarks

Natively and easily edit and open bookmarks in multi-account containers.



Usage

• Quickly bookmark the current page + container combo
• Assign a container from the bookmark context menu
• Easily edit assigned bookmarks with the native bookmark UI
• Assign whole folders in one pass
• Choose where quick bookmarks are saved from the options page

Security

ContainMarks prefixes a one-time code (a token) to all assigned bookmarks. This ensures only bookmarked pairings open in the assigned container.
If you experience any issues with stale tokens, the extension preferences page (read more below) may be able to help.

Sync

ContainMarks now works with Firefox Sync / bookmark transfer methods.

Slightly more technical details

Security Tokens

When a bookmark is assigned to a container, it's assigned a random token.
It's prepended to the existing URL, as well as the prefix about.
E.G. https://example.com -> about:r4nD0Mt_k3n:4:https://example.com

The middle number is the stable, first-seen container mapping index.

Sync Mapping Folder

ContainMarks stores container mapping bookmarks in the Bookmarks Menu under ContainMarks Sync.

• Folder location: Bookmarks Menu (menu________)
• Mapping bookmark title: Mapping: {containerName}
• Mapping bookmark URL: about:{firstSeenIndex}:{cookieStoreId}:{backupName}

This keeps container references stable across renames and helps sync behavior across devices.

Token Retention Options

Token retention behavior is configurable in the options page:

• Regenerate tokens on startup toggle
• Regenerate tokens on every use toggle

Page-Action Bookmarking

The page-action shortcut always creates a bookmark for the current tab URL.

• If the tab is in a container, the bookmark is container-mapped.
• If the tab is not in a container, a plain bookmark is created.

Runtime Architecture

• src/backgroundApp.ts: event orchestration (startup, tab update handling, context menus, page-action flow)
• src/containerMappingStore.ts: stable index mapping + bookmark-backed sync persistence
• src/containerMappings.ts: URL codec for bookmark and mapping formats
• src/settings.ts: settings sanitization, validation, and storage boundaries

This separation keeps encoded URL rules and sync mapping persistence independent from browser event wiring.
