Features & Capabilities

An AI-powered privacy-first browser extension that automatically detects and censors NSFW content in images, GIFs, and videos on any webpage.

Censr is a free, source-available and privacy-first AI content filter that runs entirely in your browser. It automatically detects and censors NSFW content in images, GIFs, and videos in real-time as you browse — no cloud, no servers, no data collection. Videos and GIFs censoring is free and will always remain free!

Unlike basic blur-only filters, Censr uses an advanced YOLO-based AI model to identify specific body parts and censor only the detected regions. You get precise, per-body-part censoring with 18 configurable detection targets — the first extension to offer real-time video censoring with per-region detection directly in the browser.

🛡 Real-time Detection: Automatically scans images, GIFs, and videos as pages load

🎬 Video Support: Censors video content in real-time (HTML5, HLS, canvas-based players)

🎞 GIF Support: Animated GIFs are processed frame-by-frame

🔒 Placeholder Blur: Content is blurred while being processed (no NSFW flash)

🎛 Customizable Censoring: Toggle which body parts to censor

🎨 Multiple Censor Styles: Choose between Blur, Black Bar, or Pixelate

🏷 Custom Labels: Replace detection labels with your own text or emojis (or hide them!)

🖼 Image Overlays: Use custom images instead of blur/bars (stickers, memes, etc.)

📏 Box Size Multiplier: Make censored areas larger (1x to 3x)

⏱ Frame Interval Control: Adjust video/GIF processing speed (50-500ms)

🔒 Privacy-Focused: All processing happens locally in your browser

⚡ Fast: Uses ONNX Runtime WebAssembly for efficient inference.

User Reviews

Thank you for creating this add-on! This tool has been great for me, and I’m looking forward to seeing what the AI can do. Lately, I’ve been watching a lot of Aion 2 YouTube videos in preparation for the global launch, and this extension has really improved my browsing and viewing experience. However, I do see some room for improvement with certain videos. In one video that I used as my guinea pig, there is a jiggle effect on a female character, and the blur doesn’t always stick. It worked most of the time, but there were a few instances where the effect became visible again. In other videos I feel like I see way more buttocks than I would like, even if the characters are wearing a swimsuit. Also, some YouTube preview/thumbnail images aren’t being blurred either. For the most part, though, this has been working great for me. Thank you again for creating this extension!

Is Censr Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Censr requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Censr is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
