About this extension
Stashmark keeps the pages you want to come back to: saved, highlighted and easy to find.

In Firefox:
  • Save the page from the toolbar with a note, tags and a reading status (Inbox, Later or Archive), or save every open tab at once.
  • Highlight as you read: select text, pick one of twelve colours and add a note.
  • Sidebar: your library and this page's highlights beside what you are reading. Search, filter, and move or trash several bookmarks at once.
  • Right-click to save a link, an image, or the page together with a quote.
  • Address bar: type "sm", a space and a few words to search your library.
  • Keyboard shortcuts: Alt+Shift+S to save, Alt+Shift+H to highlight, Alt+Shift+P for the sidebar, Alt+Shift+Q to quick save. On a Mac, use Option instead of Alt.
  • Works offline: saves made without a connection wait on your device and sync when you are back online.
  • Trash with Undo: removed bookmarks are kept for 30 days.

In your Stashmark library on the web:
  • A clean reader that keeps a copy of each article, even if the page changes.
  • Every highlight in one place, with search, filters and export.
  • YouTube and Vimeo transcripts, synced to the video.
  • On Pro: AI summaries, automatic tagging and full-text search. On Pro+: listening in natural voices.

Private by default. No analytics, no tracking and no remote code. The extension asks for no access to all sites when you install it; that is only requested if you turn on the saved-page indicator.

Needs a free Stashmark account and Firefox 140 or later.
Developer comments
Stashmark needs a free account: sign in from the toolbar button or the welcome tab that opens after install.

Keyboard shortcuts can be changed in Firefox's Add-ons Manager, under Manage Extension Shortcuts.
