What's New in v3.0.0?

We just released NSFW Filter v3.0.0 . This is the biggest update the extension has had in years. Here’s what changed.

Rebuilt for Manifest V3

Chrome is removing the old extension format (Manifest V2) that earlier versions of NSFW Filter were built on. v3.0.0 is a full rewrite onto Manifest V3, so the extension keeps working on current and future versions of Chrome. The way you use it does not change.

Still completely on-device

This part has not changed, and it never will. Every image is classified right inside your browser. The AI model ships with the extension, so nothing you look at is ever sent to a server. No accounts, no analytics, no remote calls. v3.0.0 keeps that promise.

Choose your model

Every version of NSFW Filter has used a single image classifier behind the scenes. v3.0.0 adds a second one and lets you switch between them. Open the advanced settings in the popup and you’ll find a “Trained model” dropdown.

The default is the original model, unchanged, so your current setup behaves exactly as before unless you decide otherwise. The new choice is a Vision Transformer model that was more accurate in our testing: it catches more explicit images and mistakes fewer ordinary ones for NSFW. Both run entirely in your browser, same as always.

Curious where this model came from and how we got it running on-device? We wrote up the whole process, from picking it to converting the weights, in a separate post .

A fresh look

The popup got a cleaner design and a new logo. You still get the same controls: choose whether flagged images are blurred, turned grayscale, or hidden, set how strict the filter should be, and add sites where it should not run.

Fewer flashes

On slow-loading pages, older versions could show an image for a moment before hiding it. v3.0.0 hides images up front and only reveals the ones it classifies as safe, so flagged images don’t flash on screen.
