About this extension
Stashmark keeps the pages you want to come back to: saved, highlighted and easy to find.
In Firefox:
In your Stashmark library on the web:
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.
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.
