Simple Sidebar Notes by Aadhaar

Simple Sidebar Notes is a lightweight, privacy-first note-taking extension designed to live directly inside the Firefox sidebar. It allows users to quickly create, edit, and organize notes without leaving the current tab, making it ideal for capturing ideas, tasks, and quick references while browsing.
The extension automatically saves notes as you type, so there is no need for a manual save action. Each note is stored locally on the user’s device using Firefox’s extension storage, ensuring that data remains private and accessible even after restarting the browser. No accounts, cloud services, analytics, or network connections are used.
Notes are displayed in a clean list view with support for keyboard navigation, allowing users to move between notes efficiently. Titles can be renamed instantly, notes can be reordered using drag-and-drop, and a built-in search feature helps locate content across both titles and note text. The layout is adjustable, allowing users to resize the notes list and editor area for comfort.
Simple Sidebar Notes focuses on speed, simplicity, and usability. By prioritizing keyboard shortcuts, automatic saving, and local-only storage, it provides a distraction-free note-taking experience that integrates seamlessly into the Firefox browsing workflow.
