Tab Notes & Highlighter (Lite) by Zion Emilio

Keep lightweight, site-specific notes and highlight text on any page without invasive permissions. The toolbar popup lets you jot a quick note per site; the note is stored locally using the standard WebExtension storage API. Click the Highlight button to inject a tiny content script that wraps your selection so you can revisit it later.

This add-on is designed with AMO best practices in mind. It does not execute remote code, uses no eval, and limits permissions to activeTab, tabs, and storage. There are no inline scripts; all logic is in separate JS files referenced from the popup and options pages. By keeping the footprint small and the code straightforward, the add-on remains reliable, maintainable, and respectful of user privacy.

Features include: a clean popup that displays the current tab’s title and host, a per-site note field, one-click selection highlighting, and a simple Options page to configure the highlight color.
