QuickAnnotate от Vn138

QuickAnnotate makes it easy to jot down thoughts right where you’re reading. Open the toolbar popup and launch the editor; a compact panel appears on the current page so you can type and save without switching apps. Notes are stored per-page and can be kept local on your device by default, or you can enable Firefox Sync to keep them available on your own devices. There are no site-wide permissions and the content script runs only when you open the editor. A right-click option lets you start a note from selected text. Everything uses safe, local browser APIs with no external services or analytics.
