Tor Browser 4.5.2 is released

A new release for the stable Tor Browser is available from the Tor Browser Project page and also from our distribution directory.

> Update OpenSSL to 1.0.1n

I take it then that Tor/Firefox are not effected by the HMAC ABI breakage that required the v1.0.1o release of OpenSSL the day after v1.0.1n?

That is our current

That is our current understanding, yes. Thus, even pointing to a system tor or copying a self-compiled tor into the respective Tor Browser directory should not break things for users.

The regular Tor Browser update in two weeks will ship with OpenSSL 1.0.1o then.

Firstly thanks for bringing out the latest update.

Secondly, according to gk, the next update of Tor Browser will include OpenSSL 1.0.1o.

Please, please, co-ordinate with Tails' developers so that Tails will have a Tor Browser that includes OpenSSL 1.0.1o and the latest updates from you guys. Your ability to work with Tails as a team and in-sync would be appreciated. For your info, according to Tails' website, the next update of Tails is scheduled for June 30.

Yes, the next Tor Browser

Yes, the next Tor Browser release is scheduled for the same day. So, everything should work out.

No, you won't. I asked the same question over a month ago and got no responses.

"New Tor Circuit for this

"New Tor Circuit for this Site" just gives you a new Tor circuit for the particular website leaving all your browser state (cookies, etc.) untouched. "New Identity" gives you basically a clean, new browser session.

Thanks guys!

Not sure if a bug - windows

What is the fix for Logjam, disabling DHE ciphers or requiring minimum bitness, and If bits, how many?

Disabling DHE ciphers is one

Disabling DHE ciphers is one option but Mozilla did not do this. Rather, the fix we backported bumped the minimum key size. It is now 1024 bits.

Ok, thanks :)

My personal experience is if you are using Microsoft Windows OS, you could try installing gpg4win and use it to verify torbrowser-install-4.5.2_en-US.exe.asc against torbrowser-install-4.5.2_en-US.exe

gpg4win is available for free from: http://www.gpg4win.org/download.html

Tor had finally been working

Tor had finally been working well for commenting on political sites. I could get a new circuit quickly, which is necessary for sites that have blocked many of Tor exit IPs. It is necessary to try many IPs before a post can get through the site's block list.

Now it is frigged up again, since getting a "new circuit for this site" reloads the page. The process takes much longer. Why did you change what had worked well?

If you people have no conception of what it is like to try and use Tor for online commenting, what in heaven's name are you using Tor for? Pirating movies?
