Built on a vector-based model, it offers a more intuitive browsing experience while keeping your data private by processing everything locally on your device. Join this Test Days event to be among the first to try out this new feature.

With this set of features landing in Firefox Beta 135, we need your expertise to help us test these enhancements and be a part of shaping the future of Firefox.
