BookStack Clipper от What_a_username

Content modes: Full article, selected text only, or link only. For "full article", the same reader mode algorithm as in Firefox is used (Mozilla Readability); if a page is not suitable for reader mode (e.g., a dashboard home page), the entire page is saved cleaned up (without navigation, scripts, or hidden elements) instead.

Two save targets: Append to an existing collection page (new entry at the top, with source and timestamp) or create each clipping as a dedicated new BookStack page – selectable per click in the popup, with a default setting.

UI options: Toolbar popup for curated saving (title, book, page, tags, note) and context menu (right-click on page/selection/link) for a quick click without requiring further input.

Privacy & permissions: Credentials are stored exclusively locally in Firefox (browser.storage.local); access to the BookStack server is only requested once its URL has been entered.

Requirements
* Firefox 128 or newer.
* BookStack instance with enabled API
* API Token: Generate in BookStack under Profile → API Tokens → Create Token (Token ID and Secret are displayed only once).
