- 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
\n\n\nSecurity\n\nContainMarks prefixes a one-time code (a token) to all assigned bookmarks. This ensures only bookmarked pairings open in the assigned container.\nIf you experience any issues with stale tokens, the extension preferences page (read more below) may be able to help.\n\nSync\n\nContainMarks now works with Firefox Sync / bookmark transfer methods.\n\nPrivacy Policy/T.O.S/C.O.C\n- We do not collect ANY information from you, everything is stored locally.
- There are no terms of service, use as you please. Do respect the MIT License, however.
- Be kind to others. This rule will be enforced by owner of this repository, at their discretion.
\n\n\nSlightly more technical details\n\nSecurity Tokens\n\nWhen a bookmark is assigned to a container, it's assigned a random token.\nIt's prepended to the existing URL, as well as the prefix about.\nE.G. https://example.com -> about:r4nD0Mt_k3n:4:https://example.com\n\nThe middle number is the stable, first-seen container mapping index.\n\nSync Mapping Folder\n\nContainMarks stores container mapping bookmarks in the Bookmarks Menu under ContainMarks Sync.\n- Folder location:
Bookmarks Menu (menu________) - Mapping bookmark title:
Mapping: {containerName} - Mapping bookmark URL:
about:{firstSeenIndex}:{cookieStoreId}:{backupName}
\nThis keeps container references stable across renames and helps sync behavior across devices.\n\nToken Retention Options\n\nToken retention behavior is configurable in the options page:\nRegenerate tokens on startup toggleRegenerate tokens on every use toggle
\nPage-Action Bookmarking\n\nThe page-action shortcut always creates a bookmark for the current tab URL.\n- 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.
