Media Extractor Pro szerző: Alice Sn0w

Media Extractor Pro is the most powerful media detection and download extension for Firefox. It intelligently finds every video, audio file, and streaming content on any webpage — then lets you preview, filter, rename, and download them with a single click.

v4.0 — What's new:

Smart Deduplication — Same video detected by DOM scan AND network interception? You'll see it only once. The extension merges identical content from multiple sources, keeping the best metadata (size, quality, resolution) from each.

Download Queue — No more bandwidth flooding. Downloads are queued and processed with configurable concurrency (1-6 simultaneous). Watch progress in real-time with per-file progress bars.

Hover Video Preview — Hover over any video thumbnail to see a live preview popup. Know exactly what you're downloading before you click.

Resolution & Duration Detection — See the actual resolution (1920x1080, 1280x720...) and duration (MM:SS) right in the popup for each video. Metadata is probed automatically.

Source Tracking — Every media shows a colored badge indicating how it was detected: DOM (page scan), NET (network interception), HLS (streaming manifest), AUTO (segment auto-grouping), or multi-source.

Batch Rename — Download multiple files with a custom naming pattern. Use variables like {title}, {quality}, {index}, {domain}, {date}, {filename}, {ext} to organize your downloads.

Watch Mode — Enable the watch icon and any new media appearing on the page will be automatically downloaded. Perfect for live feeds, playlists, and infinite scroll pages.

Size Filter — Drag the slider to instantly hide small files (thumbnails, previews, ads). Only see the content that matters.

Download Best — One-click button to download the highest quality version of each unique video on the page.
