Sticky by Auri

Sticky is a quick capture tool for anything you find while scrolling and don't want to lose or come back to it later, for example a Reddit post, an article, a video, or just a thought worth jotting down , by just a keystroke
Capture instantly
• Press a keyboard shortcut (customizable in Firefox's shortcut settings) to save the page or, on Reddit, the specific post you're currently viewing in the feed.
• Or right-click any link, image, or selected text and choose "Save to Sticky."
• Save a plain text note with no link at all, for ideas you just want to remember.
Organize your way
• Create custom labels and filter your saved items by them.
• Add a note to any saved item, at any time.
• Every item keeps a thumbnail, so your library is easy to scan visually rather than a wall of text links.
Fully private
Everything is stored locally in your browser. No account, no server, no sync, no data collection of any kind. Your saved items never leave your device. Export/import is available for your own backups.
Sticky is open source, source code and issue tracker on https://github.com/lousyass/sticky
