New Release: Tor Browser 8.0


Update (09/07 10:15 UTC): We received reports of Tor Browser 8.0 crashing during start-up on older (10.9.x) macOS systems. This is tracked in bug 27482. The current Tor stable version,, is missing a patch to make it compatible with that old and unsupported (by Apple) macOS version. This will be fixed in the planned Tor Browser 8.0.1 release. Meanwhile, users affected by this bug can try the almost identical alpha release, 8.5a1, which is shipping a newer Tor version with this bug fixed. Sorry for the inconvenience.

For the past year, we have been collecting feedback on how we can make Tor Browser work better for you.

Tor Browser 8.0, our first stable release based on Firefox 60 ESR, is now available from the Tor Browser Project page and also from our distribution directory. This release is all about users first.

Tor Browser 8.0 comes with a series of user experience improvements that address a set of long-term Tor Browser issues you’ve told us about. To meet our users' needs, Tor Browser has a new user onboarding experience; an updated landing page that follows our styleguide; additional language support; and new behaviors for bridge fetching, displaying a circuit, and visiting .onion sites.

New User Onboarding

For the most part, using Tor is like using any other browser (and it is based on Firefox), but there are some usage differences and cool things happening behind the scenes that users should be aware of. Our new onboarding experience aims to better let you know about unique aspects of Tor Browser and how to maximize those for your best browsing experience.

Improved Bridge Fetching

For users where Tor is blocked, we have previously offered a handful of bridges in the browser to bypass censorship. But to receive additional bridges, you had to send an email or visit a website, which posed a set of problems. To simplify how you request bridges, we now have a new bridge configuration flow when you when you launch Tor. Now all you have to do is solve a captcha in Tor Launcher, and you’ll get a bridge IP. We hope this simplification will allow more people to bypass censorship and browse the internet freely and privately.

Better Language Support

Millions of people around the world use Tor, but not everyone has been able to use Tor in their language. In Tor Browser 8, we’ve added resources and support for nine previously unsupported languages: Catalan, Irish, Indonesian, Icelandic, Norwegian, Danish, Hebrew, Swedish, and Traditional Chinese.

Apart from those highlights, a number of other component and toolchains got an update for this major release. In particular, we now ship Tor with OpenSSL 1.0.2p and Libevent 2.1.8. Moreover, we switched to the pure WebExtension version of NoScript (version which we still need to provide the security slider functionality. Additionally, we start shipping 64bit builds for Windows users which should enhance Tor Browser stability compared to the 32bit bundles.

Providing this many improvements for our users could only be possible with collaboration between the Tor Browser team and Tor's UX team, Community team, Services Admin team, and our volunteers. We would like to thank everyone for working hard over the past year to bring all these new features to our users.

Known Issues

We already collected a number of unresolved bugs since Tor Browser 7.5.6 and tagged them with our ff60-esr keyword to keep them on our radar. The most important ones are listed below:

  • WebGL is broken right now.
  • We disable Stylo on macOS due to reproducibility issues we need to investigate and fix. This will likely not get fixed for Tor Browser 8, as we need some baking time on our nightly/alpha channel before we are sure there are no reproducibility/stability regressions. The tentative plan is to get it ready for Tor Browser 8.5.


Note: This release is signed with a new GPG subkey as the old one expired a couple of days ago. You might need to refresh your copy of the public part of the Tor Browser signing key before doing the verification. The fingerprint of the new subkey is 1107 75B5 D101 FB36 BC6C 911B EB77 4491 D9FF 06E2.

Give Feedback

This is only the beginning of our efforts to put users first. If you find a bug or have a suggestion for how we could improve this release, please let us know.

I suggest that the Exec Director assign someone to update anything having to do with signing keys used by users to verify the latest release of TB, including

o checking certificates used at TP websites and generating new ones before they expire

o extending lifetime of signing subkeys or generating new subkeys

o updating the webpage listing the signing keys used by TP

o sending latest key information to keyservers (recommended keyservers would be a good item to add to the webpage, but might need to be updated regularly).

TP should not perform these critical tasks in such a haphazard manner, which tends to suggest TP doesn't think it matters because TP knows something users do not (yet), probably related to FBI's "Going Dark" monomania.

How would I go about disabling connection though Tor network, while preserving other browser features? On Tor Browser 7.5.6 it was done by setting about:config => network.proxy.socks_remote_dns to false and setting Options => Advanced tab => Network to No Proxy (the recipe is borrowed from here), now it doesn't seem to work (Tor Browser simply looses network connection). Is it at all possible to achieve in Tor Browser 8?

Hm, this works for me. Just loading that page should trigger the problem, right? Which exact Windows bundle are you using (32bit? 64bit? locale?)? Does it work for you if you install the 64bit version of Tor Browser downloaded from our website to a different location?

Yeah, trying to load the page and the error pop-up. Iam using Windows 7/ 32 bit. Tried to install the 64 bit version as for tor........not possible, wont let me do that since i have a 32bit operating system.....unless there is a way to do that, which i dont know..............thanks in advance

Hm. Do you have some Antivirus/Firewall software installed that could be interfering here? If so, which and could you uninstall it for the time being to test whether that solves your problem? (disabling is often not enough)

someone stated it clearly, so i'm only going to echo his words. this version of Tor should have never been released yet, it's just not ready at all. you're putting a lot of users at risk for no good reason

NoScript has an icon for 'Reload' but NoScript does this
How can one prevent this?

I want to know this too

I'm unable to run TBB 8.0 on my system apparently because it's based on FF Quantum. Is there a way to at least update only Tor in TBB 7.5.6? Simply overwriting the files from unzipped 8.0 didn't work.

Thats a good question,
are you running XP?

maybe open a ticket, thanks

Nem jó! Remeg a képernyő! Ledobál email írásnál, összeömlik, újraindul! nem jó! És ugyna olyan lassú!

How do you change tor identities on this version of Tor Browser?

Go to File-new identity

Why the option from onion drop-down menu for making new session has been gone?

That moved to the main menu (click on the three horizontal bar icon).

Bug 26321: Move 'New Identity', 'New Circuit' to File, hamburger menus....

No, it looks like sandwich not hamburger at first glance at the icon, it's the main menu of FireFox.

Is browserleaks dot com a useful website to check how your browser performs in terms of privacy and security?

when I click on the HTML5 Canvas Fingerprinting it knows I am using Torbrowser?

Uniqueness × False (Tor Browser signature)

We don't hide the fact that Tor Browser users are Tor Browser users. So, it's okay if any site is saying "You are a Tor Browser user". I don't think that website is a good one regarding the security track record of your browser. Nor do I think it is a good one for showing how you fare with respect to your privacy. I don't have a good one for recommendation right now, though, alas.

I am sad that you no longer support windows XP. After years of using it I know where every storage file is located which I can wipe after use. I find linux a pain up the butt to setup due to its constant need for your setup passwords. Now it seems I can't use any onion sites and I am not going to pay all that money for a new windows OS. So good luck and farewell.

I suspect the developers are using the latest computers and software and have forgotten half the world are still using older stuff. I just got an error message "your system is short on virtual memory please shut down and restart". I keep the paging file disabled and never have problems as I have at least 2gb RAM. Seems like many are having problems with this newest version.

You should be pushed to new hardware so you can be more easily tracked.

So, why is DDG still being used as the default search engine?
It seems to track searches done by users, which is bad from a privacy point of view.

There' re probably other options available for a default engine, right?
Or does it come down to financial support (which is an understandable reason)?

Previously I was able to comment on news websites using my fake Facebook account if I allowed third party cookies in the Tor browser but now even if I allow third party cookies websites don't know I am logged in to Facebook and I am not able to comment on the news articles.

For me the recent upgrade from TB7.x to 8.0 broke noscript.
Noscript says it was working but it clearly was not when a (luckily non malicious) website managed to run a jacascript.
I looked and the default setting in Noscript was Trust All
Check your settings and visit a safe site to test them.
Developers: Please make sure the package installs without compromising security.

"I looked and the default setting in Noscript was Trust All", yes, that's right. NoScript's default setting is "Trust All". See: for some reasoning behind that.

bing translator doesn't work any more on this version of Tor Browser

That's and will be fixed in the upcoming 8.0.1 release.


Tor Browser 8.0 issue report:
don't wanna all blahs? go to "The issue" bellow

Had just downloaded and used today.

DISTRO: torbrowser-install-8.0_en-US.exe win32
MD5: acb44ca853c1c4a7359a53e6486cf723
TARGET PLAT: a very dodgy[1] windows 7 install


The issue:

It's openning SOME pdf files with the internal pdf
applet instead of downloading it - EVEN AFTER manually
configuring the Options-Apps-PDF-download option.

Dunno if it's FF or TB issue. PLS let FF team know!

I'm guessing it's failing when the target file have
a dodgy fname extension on it.
Those "fname templates" used to be downloaded normally
in the previous version.


[1] everybody putting their hands on, leaking through all
it's pores - evil forces sanctuary - (but TOR networking
seemed fine - no leaks).

The internal Tor Browser circuit viewer has never worked for me. I assume it has something to do with my usage of Qubes-Whonix (and perhaps it doesn't work on regular Whonix either). Is this a Tor Browser bug or a Whonix bug most likely? Exactly how does the circuit viewer work? Getting a new circuit works fine so it has some access.

I am inclined to say this is a Whonix bug but I am not very familiar with it, so it is hard to say. The circuit display works by keeping track of circuits per domain: Tor in Tor Browser uses different circuits for different domains and is asking via the control port about their status. On getting that back from Tor it constructs the display for the currently visible domain in the URL bar.

I tried to get my higih sierra mac to send data through the TOR browser. I used sock proxy server with with port 9150. It works but the DNS used is the DNS picked up from my computer or entered manually on my computer. Can I use the TOR browser to sent my DNS request through.

Will the next stable release have the latest OpenSSL 1.1.1 and TLS 1.3?

I'm sorry but the new UI is really bad. I have no idea how to do anything now. And now I'm afraid I'm going to end up messing up something. However, I'm very pleased that Tor Browser is based on a newer and more secure Firefox base but I highly recommend that newer Tor Browser versions go through more rigorous UI review to prevent users from inadvertendly hurting themselves due to infamiliarity with the UI.

It works very well in my Fedora 25.Thanks!

Usually Tor browser blocked the images, but you could allow them ("allow in the future") clicking in the "palette" icon in the left of the navigation bar which appears when some image was first blocked.
Now I dont find this option anymore, and sites like whatsapp.web cant load the QR code image...
Like in my office where I need Tor to access this sites for proxy blocking reasons, I cant find a solution for this issue.

До обновления было всё хорошо, работало без нареканий. После обновы стал висеть как фанера над парижем. Как откатить обнову? Бесит. Работала в 8-11 вкладках, сейчас тянет только 1 и то со скрипом!

Does this happen as well with the 64bit version of Tor Browser (assuming you were using the 32bit one on Windows)?

Can you please push my most dearest Mozilla Inc. to set
in Firefox, too?
Would be very very nice.

I don't like ...unasked phone-home.

It looks like that the desktop icon for Tor Browser is missing on Linux.

I only use Relays and Guards that run current version of Tor and do not have the flag "Not Recommended". New version 8.0 allows for a new circuit but binds you to the same guard...that often is "Not Recommended". You guys don't need me to tell you that ALL things must be correct when establishing a secure connection. If we can not change the Guard when necessary it renders Tor useless as a (best of) security option. ----- hate to say this but the new design makes it difficult for new users to get Relay Information and as someone who pays attention to UI it seems intentional! Hard to check relay, no way to change Guard...this could conjure up conspiracy theories or resurrect old established ones. PLEASE advise as best way to change a complete circuit, including the Guard. -- Thank you

This seems like a rather pressing issue. I think i'm not alone in feeling like this should at least be addressed with a comment from the team..


I downloaded:
Tor Browser for Windows (64 bit)

I also downloaded the "sig".

gpg is not able to confirm the "sig", without the public key.

Whose public key do I need to find?
From where do I get the public key?

Thank you.
