X Video Downloader 作者： Sneg

Download videos from x.com (Twitter) with one click.

A round download button appears on every post containing a video or GIF — on your timeline, profiles, search results, and tweet pages. One click saves the MP4 straight to your computer.

Features
- One-click download button on every video post
- Best quality by default (highest-bitrate MP4); Medium/Low options in settings
- Saves to a folder of your choice inside Downloads, or opens a Save As dialog so you can pick any location
- Multiple videos in one post are handled individually
- Customizable UI: dark/light/auto theme, 8 accent colors, button size, corner position, opacity
- No re-encoding — the original video stream is saved as-is

How it works: the add-on reads Twitter's own GraphQL API responses as you browse to locate video files, then hands the direct MP4 link to Firefox's download manager.

Privacy: collects nothing — no analytics, no tracking, no accounts. Settings stay on your device.
