Page Toolkit от 32win

Page Toolkit collects essential page context in a single click and keeps it tidy. Open the toolbar popup to fetch the title, URL, and top heading from the active tab, optionally including the current text selection. Save it automatically to extension storage so it’s available when you need it, or copy it to the clipboard for quick sharing. The add-on also provides a right-click “Grab Page Info” shortcut for pages where you prefer not to open the popup.

The add-on follows Firefox Add-ons policies: scripts are kept in separate files (no inline JavaScript), no remote code loading, and no use of eval. Permissions are kept minimal: activeTab gives temporary access to the current page only after user interaction, tabs is used to query and inject the content script from the popup, storage saves preferences and the most recent capture, and contextMenus enables the opt-in right-click item. A strict Content Security Policy is applied in the manifest.
