ContainMarks

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



Compatability

This extension works well with both Temporary Containers on the Mozilla-Addons-Store and Temporary Containers Plus on the Mozilla-Addons-Store.



Usage

(see the screenshots above, or head to the repository for gifs)

• 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 attaches a one-time code (a token) to all assigned bookmarks. This ensures only bookmarked pairings open in the assigned container.

Sync

ContainMarks works with Firefox Sync / bookmark transfer methods.

Slightly more technical details

Security Tokens

When a bookmark is assigned to a container, it receives a random token and a stable container index. The assignment is embedded in the URL's fragment, so the real URL remains intact and navigable.
E.G. https://example.com -> https://example.com#cm:r4nD0Mt_k3n:4

If the original URL already had a fragment (e.g. https://example.com#section), it is preserved after the encoding:
https://example.com#cm:r4nD0Mt_k3n:4#section

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

This token is hidden when the user goes to edit the bookmark. It is hotswapped back in when the bookmark is saved. This makes native bookmark editing possible without exposing the internal workings of the extension or requiring users to not mess with the token in the URL. This is a slight oversimplification, but this is ~90% correct. Read the code for the full details.

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.
