Snipper od Heiko

Snipper is a lightweight Firefox extension for collecting text as you browse.
Highlight any text on a webpage, save it instantly, and keep browsing. Snipper stores each snippet with its source, timestamp, and context, so you can return to it later without losing where it came from.
Clicking a saved snippet reopens the original page and automatically highlights the exact section it was taken from — perfect for research, comparison, writing, or shopping.
Snipper works completely offline using local storage. Optional Firefox Sync lets you share snippets across devices when you want, with a subtle visual indicator showing when sync is active.
