123Movies Video Downloader

Overview

A movie found on a 123Movies mirror tonight could be gone by tomorrow. Domains change, links break, and content you planned to watch later vanishes. Save it as an MP4 file on your own computer and watch it whenever you want.

This browser extension works across 123Movies mirrors and domain variants. Press play, click the extension icon, pick your quality, and the video downloads straight to your device. It handles full-length films reliably, with smart retry logic that keeps long downloads on track even when your connection drops. No extra software, no command line, no screen recording workarounds.

Everything happens inside your browser. The video never touches a third-party server, so what you download stays between you and your hard drive. Three free downloads are included so you can try it before committing.

FAQ

How do I download a video from 123Movies?

Open a supported 123Movies mirror, start playing the video, click the extension icon, choose your preferred quality, and start the download. The extension detects the active stream and saves the finished video as an MP4 file.

Do I need to press play before detection works?

Yes. The extension detects the stream after playback starts. If no video appears in the popup, press play first, wait for the stream to load, and then open the extension again.

What quality options are available?

When the source provides multiple renditions, the extension can show a manual quality selector alongside an automatic best-quality option. Typical stream variants depend on the mirror and may include resolutions such as 720p, 480p, or 360p.

What format are the downloaded videos?

Videos are saved as standard MP4 files. HLS streams are stitched and converted to MP4 in-browser, while direct MP4 sources are saved directly when available.

Does it support multiple downloads at once?

No. This downloader is optimized for one video at a time so the active stream can be processed cleanly. Start the next download after the current file finishes.

Will this work on every 123Movies domain?

It is designed for 123Movies mirrors and domain variants, including domains containing "123movies" or "123-movies". Support depends on the mirror exposing a compatible video stream and not using DRM.

Why is the extension requesting these permissions?

123Movies mirrors often use redirects, embedded players, and hidden stream manifests. Permissions like tabs, webRequest, scripting, and downloads let the extension detect the active video, resolve the real media source, track progress, and save the MP4 locally.

Which browsers are supported?

Desktop builds are available for Chrome, Edge, Firefox, Brave, Opera, Whale, and Yandex on Windows, macOS, and Linux. Safari and mobile browsers are not supported.

Why is my video not being detected?

Press play first and give the stream a moment to initialize. If the mirror still does not appear, refresh the page and try again. Detection also fails on unsupported or DRM-protected streams.

Is there a free trial?

Yes. You get 3 free trial downloads after signing in with your email. After that, the product uses a paid subscription for unlimited downloads.

Is my data private?

Yes. Video processing happens locally in your browser. Authentication uses secure OTP email verification, and the extension does not upload video files to external servers.

Is this legal?
