New Release: Tor Browser 9.0a2

Tor Browser 9.0a2 is now available from the Tor Browser Alpha download page and also from our distribution directory.

This release is fixing regressions and providing small improvements similarly to our 8.5.1 release. Additionally, we update Tor to, OpenSSL to 1.1.1c, we disable the WebGL readPixel() fingerprinting vector, add the ro locale, and start updating our toolchains in prevision to the planned migration to Firefox 68 ESR.

Why is there two versions on F-droid? Which one should users use? And why is the Play Store seemingly getting more updates?

There is an alpha and a stable version. If you want to help us find bugs in new features use the alpha one and the stable otherwise. The Play Store is getting updates faster as this is a process controlled directly by us. For F-Droid we still need to ask the Guardian Project folks to upload new versions for us which is a manual process and costs time. But we work on fixing that:

bridges are such a pain now. when picking auto ones it is very slow, plus there is only 3 bridge lines for maual input. can that be increased to something like orbot where a user can put more than 3? I had several issues where all 3 bridges I got manually are either very slow (1-2 kbps) or just not working and this goes for all bridge types.

final question: in manual input it says address:port, so does that mean for obfs4 bridge lines there is no need for the rest of the line?

thank you

then it should say so because it is confusing now. And I hope you would consider bridge spaces in the future and make it just like orbot where its possible to put more than 3 in case all 3 are not working which is happening to me now and also not to have to paste the lines one by one, a single space for all bridges is much better and time saving.

by the way bridgedb is still fetching non working bridges and its sooo time consuming to get a working one and the default bridges in torbrowser are not working

for people relying on bridges this is like a total tor outage, hope you could do something about it

What is your operating system? I am able to enter as many as I want on desktop version. The vertical size of the box is 3 lines, but press Enter after 3 lines, and a scroll bar displays. Go on typing.

Only obfs4 and meek are recommended right now, and meek is basically for users in China.

TorButton --> Tor Network Settings --> "Provide a bridge I know" does say "type address:port (one per line)". Good point. I was not able to find an answer in the documentation manuals or support or old site except for one page in BridgeDB that says, "copy and paste the bridge lines into the text input box." Paste the entire line into the box. TorButton's description in the empty text box should be improved.

What about the DDos Vulnerabilities of onion websites? Is that going to get fixed?

Hello, please, help me. I have a Linux laptop and want to run a free virtual machine (prefer a hypervisor) for commercial use. Highly important privacy.
1. What a matches have? (If I right understood, Proxmox will delete all data from the host machine. No need.)
2. Is there any matches without a GPL, Apache or like it license?
3. What exactly goals have TAILS? What a negative points it have? It can be run without a USB-device?
4. How to recognize, what a system I have, 64 or 86? If hypervisor made for x86 (like KVM) it possible to run this vm on the x64 computer? Can I run bhyve on the Linux laptop? How I can find usual info about system?
5. Where I can anonymously ask any questions like that? (Better if without a registration and with Tor-safest enabled.)

1. This is not the place to ask. This site is about Tor Project.

2. GPL and Apache are notably different. Learn about free/open source licenses. Running the software is not the same as redistributing, modifying, or linking libraries.…

3. Tails is not managed by Tor Project. Go to Tails Help & Support. It can be run from a DVD, USB, or as an ISO file if mounted to boot in a virtual machine manager.

4. You wrote that whole comment but didn't type a few keywords in a search engine right there in your browser. Show some effort. Example results 1, 2. In general, the width of memory addresses is not backwards-compatible. Most end-user hardware such as laptops since the middle 2000's decade are 64-bit. Old devices and some small ones are still 32-bit. A 64-bit machine can run 32 or 64 bit software. A 32-bit machine can run only 32-bit software unless the processor supports VT-x/AMD-V for running a 64-bit virtual machine.

5. IRC and other chat services, technology imageboards... It's very hard to find websites that don't demand javascript and registration anymore.

The new v3 addresses are great, but is there any official support for "link shorteners"? Or any other suggestions for human memorable onion domains? This is for sites where the content is hosted anonymously, but not illegal so people may access it via a tor2web type gateway.

We are working on that problem but it's not an easy one. For some background see:

Be aware that tor2web gateways are able to log visits and log what content the visitor accesses. It's best to use Tor Browser to access onions if you can install it.

Is Windows 10 up to something? I cannot get Tor to work, it says another is running and needs to be shut down. I have re-downloaded it and have to do it every time. When it says copy log to Tor, then it says 0 log entries so have nothing to copy. It just will not start. Even with a fresh download. I am new using Asus Laptop with Windows 10. Am I being sabotaged by Win 10? I have used Tor for years but it seems W10 doesn't want it?

So, a fresh copy is working for you but as soon as you try to start that a second time it fails? Do you delete the old version first or are you installing the new Tor Browser just over the old one? Or a you putting each new Tor Browser into its own directory?

Yes that’s it


What does that mean? How to solve this problem?

It means that you switched to use a bridge but that the bridge is not available (maybe just temporarily down or blocked). You need to get a working bridge from places like BridgeDB:

Thanks for the great work you do!

For the few situations when Tor can't be used, and yet TorBrowser's benefits are still desired, what's the best way to disable Tor Launcher?
There are old suggestions online, but since Tor Launcher is recently removed from the FF "Add-ons" list, and hence can't be disabled there easily, Tor Launcher reverts the TB proxy settings on each restart.


Please notice it is not recommended. There is an advanced option. You can open about:config, search for extensions.torbutton.use_nontor_proxy, and toggle it to true.


Hi to you all .I am not here to speek about ttb android, because I am not seeing issues. Well just reporting that is good .
Does anyone know tell me something about Icecat web browser for mobile, ? On fdroid it sponsored not that it can use tor ,but once opening setup you can find a tor button. Like private browser more or less. But it does not works trough orbot and not by itself :( .Thx.

> once opening setup you can find a tor button

What does the button/icon look like? If it's a shield, it could be Mozilla's "Enhanced Tracking Protection" which is not a Tor icon but a new thing in Mozilla Firefox.

Any thoughts on #27590? I think informing the user about the alt-svc header is valuable. I've noticed several sites doing it, in addition to Cloudflare.

"Mozilla patches Firefox zero-day abused in the wild. Mozilla releases Firefox 67.0.3 to fix actively exploited zero-day."…

What about Tor Browser? Thanks!

I would love to help run relays or whatever I can to help but honestly I'm not up to par on coding like you guys are. Wanna teach a newbie, im game.

Alpha working perfect. I ONLY use Orbot and also Quantum Flare (for tracker & malware protection), and never had to root my droid devices.

Long live Tor!
