New Release: Tor Browser 10.5

Tor Browser 10.5 is now available from the Tor Browser download page and also from our distribution directory.

This new Tor Browser release is focused on improving the internet access of users connecting through Tor in censored contexts.

What's new?

V2 Onion Services Deprecation

Tor Browser 10.5 V2 onion addresses warning

As we announced last year, v2 onion services will be completely unreachable once Tor Browser moves to Tor 0.4.6.x in October 2021. From now until then, Tor Browser will warn you when visiting a v2 onion site of its upcoming deprecation.

Snowflake is now available as a bridge

Tor Browser 10.5 Snowflake bridge

With Snowflake, censored users can rely on proxies run by volunteers to connect to the internet.

During Q1 this year, the UX team ran a survey on Tor Browser Alpha to better understand Snowflake’s user experience. The survey received 1,795 complete responses, of which 726 participants confirmed they use Snowflake as a pluggable transport. The majority of Snowflake users who completed the survey began using Tor Browser several times a week within the past year. 75% of users had a positive view of Snowflake, although many experienced connection troubles and slow speeds while browsing. These facts and the stable network of volunteers allow us to make it available on this release.

Improving the user experience of connecting to Tor

Tor Browser 10.5 about:connect

Tor Launcher has acted as the options panel for advanced Tor network configurations over the years. It also serves as a control point for users who are in censored networks. The UX and the Anti-Censorship teams joined efforts to improve the connecting flow for Tor Browser users. This release is the first in the upcoming series of helping censored users seamlessly access the open internet by simplifying the connection flow, detecting censorship and providing bridges.

For tor browser 10.5, the change in connecting to TOR is not leaving the cursor in the address bar, which is inconvenient (but not quite so inconvenient as the failure of saved passwords, which you have an open bug for).

Also, it would be really helpful for anyone reviewing this page if the Known Bugs had the bug title next to them so they don't waste time opening each one to see if it of relevance to them.

HTH,

Chuck

Hello. Sorry if this is the wrong place to ask, but is the torrc file ignored by the current built or is that just me? Thank you for your time.

2 issues in 10.5:

1. "DuckDuckGoOnion" search provider is still using the v2 address.

2. Tor browser windows size is "1052 x 714" upon launch, but it is "1054 x 715" after using the "new identity" button. (Ubuntu 18.04.5 LTS / Xfce 4.12)

For number 2, check your window size dimensions here:
- https://fpcentral.tbb.torproject.org/ -- Do "Run JavaScript Tests". Look for screen.width, height and screen.availHeight, Width.
- https://arkenfox.github.io/TZP/tzp.html -- Look under the header labeled "screen".

The dimensions that a website sees should be a multiple of 200x100 px. The outer size that I think you are talking about should not matter in terms of fingerprinting. Did you change the vertical size of the inner content panel by, for example, enabling a toolbar?

You performance may vary depending on your location and your local network setup. Some users with very restrictive firewalls on their home networks, or users connecting over a mobile network, experience a long delay in the initial bootstrapping of the Tor connection. We're continuing to work on improving the performance of Snowflake.

I have two questions =) first) why i had to configure addons(noscript+https) icons manually(so they can be shown on a toolbar), and second all pages in fullscreen mode opening with white borders on both corners of browser's window. I'll be very thankful if you will be able to find some time to answer my questions. Thank you

OnionCircuits does not work after updating to 10.5.
Console shows 'Tor requires a password to authenticate'.
but nyx works fine without password.
I'm on ubuntu.

Snowflakes are more ephemeral than other bridges. If the snowflakes offered to a client go offline while the client is in a session, does the client automatically request new snowflakes in that session? Is such a request made to the front domain, or is it anticipated by the client and requested through the remaining snowflakes before the last one known to the client goes offline?

Tor Browser 10.5.2 on linux doesn't follow system theme as before.
I have a dark desktop and before Tor Browser follows the dark theme, now it has its default light theme.
