New Release: Tor Browser 8.0a9

Tor Browser 8.0a9 is now available from the Tor Browser Project page and also from our distribution directory.

This release features important security updates to Firefox.

Tor Browser 8.0a9 is the first alpha release based on Firefox 60 ESR. We rebased all of our patches, updated our toolchains to pick up new requirements like Rust support, and fixed the most important usability issues and broken functionality.

We rely on your feedback to make Tor Browser better for users around the world. Releasing a Tor Browser alpha before each stable release gives us a valuable window of time to learn about and fix bugs before the stable release is used by millions.

New Features

If you are comfortable with Tor Browser, we need your help! This alpha has a lot of new features, including a couple major UX changes, and we want them to be in tip-top shape before the stable release hits this September. Here's a taste of what's new:

  1. Improved Circuit Display:

    We've heard a lot of confusion about how the first guard in the Tor Circuit Display stays the same for months, even if you select "New Identity." This is by design, so now, we're trying to to better communicate that to the user and better manage expectations about both "New Identity" and "New Tor Circuit for this Site."

  2. Onion Indicators:

    We're trying out a new system for indicating .onion sites' relationships to TLS certificates. We mapped all the current padlock states Firefox has for sites' TLS certificates, and from there, we've built a new system for communicating these states when they are related to .onion sites.

  3. New Locales: We added support for da, he, sv-SE, and zh-TW to give users speaking those languages an improved Tor Browser experience. The plan is to add even more locales once we are confident we can handle the additional load and disk space requirements.
  4. New Torbutton Icon: We replaced our old Torbutton icon with a shiny new one. That's the first step in redesigning Tor Browser icons and making them compatible with Firefox's Photon UI. There is more to come in the next alphas.
  5. Full Sandboxing Support for Windows: We are able to provide full content sandboxing support for 64bit Windows bundles now, thanks to the work done by Tom Ritter.

Additionally, we updated a number of components we ship: Tor to, Torbutton to 2.0.1, TorLauncher to, HTTPS-Everywhere to 2018.06.21, and NoScript to Expect more bugs than usual in this alpha.

Known Issues

We already collected a number of unresolved bugs in Tor Browser 8.0a9 and tagged them with our ff60-esr keyword to keep them on our radar. The most important ones are listed below:

  1. Meek is currently broken. We need to update the browser part for make it compatible with ESR60.
  2. On Windows localized builds on first start the about:tor page is not shown, rather a weird XML error is visible.
  3. Maybe related to 2) NoScript does not seem to work properly on Windows builds right now.
  4. We are not done yet with reviewing the network code changes between ESR52 and ESR60. While we don't expect that proxy bypass bugs got introduced between those ESR series, we can't rule it out yet.
  5. We disable Stylo on macOS due to reproducibility issues we need to investigate and fix.
  6. We ran into issues while creating the incremental update files. In order to avoid respinning yet another release candidate and redoing the signing work, we opted into patching our mar-tools locally. For those of you who want to reproduce our builds (please do!) bug 26472 has steps that explain what we did.

Give Feedback and Report Bugs

If you find a bug or have a suggestion for how we could improve these changes, please let us know. There are several ways you can reach us with feedback about this alpha including commenting on this post, emailing us at, or contacting the developers at the tbb-dev mailing list. We track all Tor Browser 8 related issues with the ff60-esr keyword in our bug tracker and are happy with bug reports, there, too. Be sure to include as many of these as possible:

  • Your OS
  • Tor Browser version
  • Step by step of how you got to the issue, so we can reproduce it (e.g. I opened the browser, typed a url, clicked on (i) icon, then my browser crashed)
  • A screenshot of the problem
  • The debug log
  • A descriptive subject line (if you're emailing us)

Thank you for your support!


Note: This alpha release is the first one that gets signed with a new Tor Browser subkey, as the currently used one is about to expire. Its fingerprint is: 1107 75B5 D101 FB36 BC6C  911B EB77 4491 D9FF 06E2. We plan to use it for the stable series, too, once Tor Browser 8 gets released.

Thanks. I updated the changelog to fix this.

This is how it looks on Linux Mint 19 with a dark theme in Cinnamon:

This isn't a bug report, more of a question of where this could be fixed to look better. Firefox? TBB? The theme maker?

Hi, how can I disable javascript now?

To disable javascript you can click the onion, select "Security Settings", then select the "Safest" level. If you don't want to change the security level, you can go to the addons page (entering about:addons in the URL bar), click on the Noscript preferences button, then uncheck the "script" check-box on the DEFAULT sites.

This doesn't work

I'ts nice

please fix the icons to make them change color with firefox test pilot's color thing

NoScript is broken on Linux 64-bit 8.0a9 but it was fine on the previous alpha. It's disabled because "NoScript is incompatible with Tor Browser 60.1.0." The version is like it's supposed to be.

Huh, it's running fine here. Did you modify the previous alpha before the update somehow? Does that happen as well with a freshly downloaded Tor Browser 8.0a9?

The "sig" for the 64bit" "8.0a9" from the TOR download page could not be verified with the downloaded program.

And the fingerprint from above: 1107 75B5 D101 FB36 BC6C 911B EB77 4491 D9FF 06E2, brings up the current (signing key - 15 Dec 14 to 24 Aug 20) when you search on a "keysever", so I am unable to the verify the downloaded program.

Please Advise - email address:

Which command did you use and what error are you getting?

This release has been signed by a new subkey, so it's possible that you need to refresh the Tor Browser key:
gpg --refresh-keys 4E2C6E8793298290

With both the "torbrowser-install-win64-8.0a9_en-US.exe" & "torbrowser-install-win64-8.0a9_en-US.exe.asc" in the same folder, I right clicked on the 8.0a9 install file and selected "Verify". This normally come back with a msg saying the two file verify, but this time I got a msg saying "The Data could not be verified."

Is there a way to attached an image file here?

I downloaded the installer twice from the Project page, and installed and then re-installed 8.0a9. I got the same result both times:

1. After clicking "Test Tor Network Settings" link to reach , the page says the browser is configured to use tor, but it is not tor browser in big orange letters.

2. There is no green padlock on "https" pages, and info from the address bar says the pages are NOT encrypted.

I have deleted 8.0a9 from my windows machine, and I will watch for further commentary here. does not recognize the new Tor Browser version yet. We have this ticket to track the issue:

Do you have an example of an https page where there is no green padlock? Is it happening on some https pages only, or all of them?

I'm back, and re-downloaded the 8.0a9 installer from on Windows for a test. All https sites that I checked report as not secure, nor encrypted. Onion sites report as secure. Here goes:
https://3g2upl4pq6kufc4m.onion/ ... duckduckgo onion
http://ulrn6sryqaifefld.onion/ ... searx onion
Thank you for your reply, and best wishes.

Hello ... I'm the same person as before who posted about no green padlocks. I have re-tested TB 8.0a9 today, and I'm getting green padlocks plus security certificate data. Some tested websites follow:
I don't know what changed, or how it changed - but thanks.

I am using Windows. The Check Tor Project page of 8.0a9 has orange graphics. The page
reports that although the browser is configured to use Tor, the browser itself is not tor browser. Also, the address bar information ("i" encircled) reports that encrypted pages are not encrypted ... starting with the Check Tor Project page itself! I have downloaded the installer twice from the project page, and installed 8.0a9 twice. I have used the Tor button installation method, also. The results are the same each time. Thanks for all that the Tor team has done for us. I will use 8.0a8 for now, and hope to see more information in the comments.

This is an issue with which does not recognize the new Tor Browser version yet. We have a ticket to track this issue:

On Windows, the Check Tor Project page reports that the browser is configured for Tor but is not Tor Browser ... in orange font. Also, encrypted pages are reported by the encircled "i" icon in the address bar as NOT ENCRYPTED (I'm not shouting, just kind of excited - that's all). I have downloaded the installer twice from the project page, and installed 8.0a9 twice. I have also used the Tor button update option. I get the same results each time. Thank you for your hard work to help us all. I'll use 8.0a8 for now until some clarification results.

I'm still not seeing my two earlier comments while you've answered my later ones. Censorship?!

Wow, I can see that as someone stated (not very politely), TP is staggering under a long long list of issues to fix just to keep TB from becoming more insecure week by week, in the face of so many technical threats.

Quick comment on appearances: IMO, security/privacy should always be prioritized over cosmetics. My main concern with FF's changing design (have they never heard of "if it aint broke dont fix it"?) forcing TB to follow suit is that regular users will be confused by appearances, possibly even harmed owing to some misunderstanding based on previous experience of using TB.

Nu? It's Jun 2018 and Form 990 nowwhere to be seen.

Yes, we are late. It seems the auditor takes more time than expected this time.

High contrast windows themes mess up the browser. I'm currently typing black on black.

Please add bridge relay's country to circuit display.

We are already discouraging Windows users to run Tor Browser as admin. Thus, I think it's not needed to backport this patch.

I removed NS when I meant to temporarily disable it. Are there any NS settings specifically for TorBrowser or can I just download it from the add-ons page? Yes or no is sufficient.

I think you can just download it from

missed in about:buildconfig?

Good question, I don't know. In fact those are not the only configure flags that are missing in about:buildconfig. I guess that's a Firefox bug.

Is that mean the current version base on the 52.x version of Firefox will be discontinued any time soon ?

The problem with this new version is that gtk3 is required, which mean dbus too along with some other lib that will help the remote seats

It will be discontinued in September as there won't be any Firefox security updates anymore then for ESR52.

ogni volta che cerco di aprire tramite Torbrowser un file .onion mi da il seguente errore:
-Impossibile stabilire una connessione con il server proxy
Firefox è configurato per utilizzare un server proxy che non risulta raggiungibile.
Verificare la correttezza delle impostazioni del proxy.
Verificare se il computer ha una connessione di rete funzionante.
Se il computer o la rete sono protetti da un firewall o un proxy, assicurarsi che Tor Browser abbia i permessi per accedere al web.
ho configurato le configurazioni avanzate come descritto in più siti, ma niente, consigli o soluzioni?

When visiting a handful of onion links, I'm told I can't view them because I need a Tor browser. Not a lot of sites, just a few...but enough to make it a pain in the butt.
