BuildBox

BuildBox gives you small, fast helpers for everyday work. Copy the current page as a Markdown link with one click, or copy a clean tracking-free URL. Turn the current selection into a fenced code block using your preferred language label from Options. When you need structure, load an on-demand outline of the page’s headings and jump to any section instantly. Nothing runs automatically on web pages: content access happens only when you click in the popup.

Under the hood, BuildBox keeps permissions lean. It uses activeTab to inject a one-off content script only after you choose a tool that needs the page, such as selection or outline. It uses tabs to read the active tab’s title and URL for link copying, storage to remember your defaults, and clipboardWrite to place text you request onto your clipboard. There are no inline scripts, no unsafe innerHTML, no remote resources, and no analytics. All code is bundled and self-hosted to satisfy AMO policies. Keyboard shortcuts are optional and can be added later if needed.
