MarkFlow от Mark

MarkFlow is a bookmarking companion for your MarkFlow account (markflow.fyi).

Features

• Save current page — title, description, OG image and a screenshot are pulled from the DOM in one click. Works offline: saves queue locally and retry automatically when you're back
  online.
• Spaces — choose which MarkFlow Space a save goes to, switch Spaces right from the popup, and keep a separate active Space per browser profile.
• Side panel — browse your folder tree, drag a page in to save it, and drag bookmarks between folders, all without leaving the page.
• Import browser bookmarks into MarkFlow, preserving folder structure.
• Import open tabs into the Space of your choice.
• Export back to Firefox bookmarks — your MarkFlow tree mirrored under "Other Bookmarks" for offline access — or export everything as a JSON or HTML file.
• Recent saves and quick search straight from the toolbar popup, plus a Global view, search across your open tabs, and resurfacing of older bookmarks.

Privacy

The extension talks only to your MarkFlow account. Page content (title, description, screenshot) is sent only when you explicitly save a page. Your browser bookmark tree is read only
during an Import you start manually. No analytics, no third-party servers, no tracking.

Connecting on Firefox

A free MarkFlow account is required. Create a personal access token at markflow.fyi/settings/api-keys and paste it in the extension's Options → Connection → Advanced. (Firefox doesn't support the automatic hand-off used by the Chrome version.)
