Deep-Mine by ProfBM

Deep-Mine is a general-purpose page scraper for Firefox. It adds a toolbar button that lets you extract, preview, and download useful content from any open tab — without leaving your browser.

📄 PDF Links
Scans the current page for all PDF links. Results open in a new tab as a checklist — select the files you want, then bulk-download them with one click. Non-file links are shown as list-only for easy copying.

🔤 Regex Pattern
Filters all links on the page by a custom regular expression you type each time. Useful for extracting links matching a specific URL pattern (e.g. .zip$, report-2024, a specific domain). Downloadable matches get a download checkbox; plain-page matches are list-only.

▶ YouTube — Video List Details
On any YouTube list page (Watch Later, Watch History, Search results, Home feed), extracts all video cards: title, URL, view count, duration, publish date, and language. Results open as a sortable, filterable table. Click any column header to sort. Toggle individual columns on/off. Shorts are hidden by default with a checkbox to bring them back.

▶ YouTube — Transcript → SRT
On any YouTube video page with the transcript panel open, extracts the full closed-captions transcript and converts it to a standard .srt subtitle file. The results page shows a live preview with a timestamps toggle (show/hide). Download the .srt file or copy the plain text (one line per caption segment) to the clipboard.

⬆ Auto-Scroll
Injects a floating control widget onto any page that auto-scrolls up or down at a fixed interval — useful for triggering lazy-loaded content before running a scan. Choose the starting direction from the popup. The widget stays on the page with a direction toggle and a Stop button (or press Esc).

All results open in a dedicated tab. Nothing is sent to any server. No data is collected or transmitted.
