Screen Recorder XT by Abdulsamet KARAKUS

Screen Recorder XT is a screen recorder for Firefox that captures your screen, webcam, and audio, then lets you trim and export your video right in your browser. Your recordings stay on your device: no account, no uploads, no analytics, and no tracking.

Record your full screen, an application window, or a browser tab. Add a webcam bubble to your screen recording, record from your webcam alone, or capture microphone audio. Choose whether to include system audio, your microphone, or both.

Whether you're making a tutorial, product demo, presentation, lesson, or video message, Screen Recorder XT gives you the tools to record and edit without relying on an online service.
Features:
- Screen recording for Firefox: capture your full screen, a window, or a tab.
- Screen and webcam recording: add a rounded webcam bubble to a screen capture, position it in a corner, and adjust its size.
- Webcam-only and audio-only recording: record a camera video or capture sound from your microphone.
- Flexible audio capture: include system audio, microphone audio, or mix both sources.
- Video settings: choose the resolution, 30 or 60 frames per second, a countdown, and a maximum recording length.
- WebM export: recordings are saved as WebM. Firefox does not support MP4 encoding in the browser; convert the downloaded file with a video converter (ffmpeg, HandBrake, VLC) if you need MP4.
- Local recordings library: search and preview your recordings, rename them, download them again, or delete them.
- Built-in video trimming: set the start and end points, remove unwanted sections from the middle, restore a cut if you change your mind, and export the edited video.
- Recovery after an interruption: recordings are written to disk in small segments as you record, so an interrupted session can usually be recovered.

Premium (optional): the free version records up to 60 seconds per capture. A Premium license (purchased via Gumroad) removes this limit. No license key is bundled with the extension; you activate it by pasting your key in the Premium dialog. Opening the dialog never opens the store — only the "Buy a key on Gumroad" button does.

Privacy: a private screen recorder that works locally. Recording, trimming, and exporting happen in your browser, on your device. There's no account to create, no video upload, and no tracking.

All recordings, settings, and license data stay in your browser's local storage (IndexedDB and chrome.storage).

The only network request is the Gumroad license verification, made only when you activate or refresh a Premium key.

Install Screen Recorder XT to record your screen, webcam, and audio in Firefox, then trim and export your video when it's ready.
