User Reviews

Users like the add‑on’s simplicity, sidebar integration and convenience for quick notes. Major complaints center on unreliable saving (lost notes), lack of multi‑note management, limited formatting/export features, and confusing options/discovery of settings.
Pros
  • Simple, minimal interface that’s great for quick jotting of notes and links
  • Integrates with the browser sidebar (left side) for easy access while browsing
  • Aesthetic and unobtrusive —many users say it “does what it says” and is pleasant to use
  • Lightweight and convenient for transferring quick notes to other tools (Obsidian, etc.)
Cons
  • Unreliable saving — multiple reports of notes disappearing/deleting and no easy recovery
  • No obvious multi-note or multi-page management (users want tabs or multiple notebooks)
  • Limited features: lacks formatting options, export tools, and some advertised features are hard to find
  • Settings/options and feature discovery can be confusing — users didn’t always find Options or where notes are stored

This extension is great, but can you add a tool that can edit or choose specific language spelling? That will be more great. Anyway, thanks.

It would be great if the extension didn't require permissions to access website content through script injection (for parsing). There are notepads that allow you to copy text from a page in the context menu, and they don't require permissions. Like Simple Notes by Firefox user 13383197. Cool notepad!
