The Tor Browser Team is proud to announce the first stable release in
the 7.5 series. This release is available from the Tor Browser Project
page [1] and also from our distribution directory [2].

This release features important security updates [3] to Firefox.

Apart from the usual Firefox security updates it contains some notable
improvements compared to the 7.0 series. Here are the highlights:
1) We redesigned parts of the Tor Browser user interface. One of the
major improvements for our users is our new Tor Launcher experience.
This work is based on the findings published at 'A Usability Evaluation
of Tor Launcher' [4], a paper done by Linda Lee et al. At our work we
iterated on the redesign proposed by the research, improving it even
further. Here are the main changes we would like to highlight:

*Welcome Screen*
Our old screen had way too much information for the users, leading many
of them to spend great time confused about what to do. Some users at
the paper experiment spent up to 40min confused about what they needed
to be doing here. Besides simplifying the screen and the message, to
make it easier for the user to know if they need to configure anything
or not, we also did a 'brand refresh' bringing our logo to the
launcher. [5]

*Censorship circumvention configuration*
This is one of the most important steps for a user who is trying to
connect to Tor while their network is censoring Tor. We also worked
really hard to make sure the UI text would make it easy for the user
to understand what a bridge is for and how to configure to use one.
Another update was a little tip we added at the drop-down menu (as
you can see below) for which bridge to use in countries that have
very sophisticated censorship methods. [6]

*Proxy help information*
The proxy settings at our Tor Launcher configuration wizard is an
important feature for users who are under a network that demands
such configuration. But it can also lead to a lot of confusion if
the user has no idea what a proxy is. Since it is a very important
feature for users, we decided to keep it in the main configuration
screen and introduced a help prompt with an explanation of when
someone would need such configuration. [7]

As part of our work with the UX team, we will also be coordinating
user testing of this new UI to continue iterating and make sure we
are always improving our users' experience. We are also planning a
series of improvements not only for the Tor Launcher flow but for
the whole browser experience (once you are connected to Tor)
including a new user onboarding flow. And last but not least we are
streamlining both our mobile and desktop experience: Tor Browser 7.5
adapted the security slider design we did for mobile bringing the
improved user experience to the desktop as well.
2) We ship the first release in Tor's 0.3.2 series, 0.3.2.9 [8]. This
release includes support for the Next Generation of Onion Services [9].

3) On the security side we enabled content sandboxing on Windows and
fixed remaining issues on Linux that prevented printing to file from
working properly. Additionally, we improved the compiler hardening
on macOS and fixed holes in the W^X mitigation on Windows.
4) We finally moved away from Gitian/tor-browser-bundle as the base of
our reproducible builds environment. Over the past weeks and months
rbm [10] / tor-browser-build [11] got developed making it much easier
to reproduce Tor Browser builds and to add reproducible builds for
new platforms and architectures. This will allow us to ship 64bit
bundles for Windows (currently in the alpha series available) and
bundles for Android at the same day as the release for the current
platforms/architectures is getting out.
