In addition to all the needed patch rebasing and toolchain updates, we made big improvements to make Tor Browser work better for you.
We want everyone in the world to be able to enjoy the privacy and freedom online Tor provides, and that’s why over the past couple years, we’ve been working hard to boost our UX and localization efforts, with the biggest gains first visible in Tor Browser 8.0.
In Tor Browser 9.0, we continue to build upon those efforts with sleeker integration and additional localization support.
Goodbye, Onion Button
We want your experience using Tor to be fully integrated within the browser so how you use Tor is more intuitive. That’s why now, rather than using the onion button that was in the toolbar, you can see your path through the Tor network and request a New Circuit through the Tor network in [i] on the URL bar.
Hello, New Identity Button
Instead of going into the onion button to request a New Identity, we’ve made this important feature easier to access by giving it its own button in the toolbar.
You can also request a New Identity, and a New Circuit, from within the [=] menu on the toolbar.
