Tor Browser 4.0.1 is released

by gk | November 1, 2014

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

Most notably, Tor Browser 4.0.1 fixes a crash bug affecting many users on Windows (see: bug 13443 for the details). Furthermore, the latest stable version of Tor (0.2.5.10) is included and a bug in our updater code got fixed.

This is not a security update, and we will not be deploying update notification or automatic upgrades for all platforms for this release. We may provide automatic updates just for Windows users later in the week, but we are hesitant to do this immediately due to Bug 13594.

Here is the changelog since 4.0:

  • All Platforms
    • Update Tor to 0.2.5.10
    • Update NoScript to 2.6.9.3
      • Bug 13301: Prevent extensions incompatibility error after upgrades
      • Bug 13460: Fix MSVC compilation issue
  • Windows
    • Bug 13443: Disable DirectShow to prevent crashes on many sites
    • Bug 13091: Make app name "Tor Browser" instead of "Tor"

It's funny for every exit node runners to see the webpages Tor users visiting through their nodes, so can you developers develope a browser like this to increase the Tor exit nodes and may speed up the Tor network.

Against the law when government find your snoop on communication. Who to tell them?

That is honestly a good question. If no one tells them that the snooping is going on (and they do nothing illegal with the data they sniff) how will anyone know?

I mean if the government really want to crack the Tor they can force the middle/entry node runners to snoop the IP address and data, why only force exit node?

Hey guys thanks for the latest release, I was hoping that 4.0.1 would of fixed my crashing issue but it still remains.

Until 4.0.0 was released I never had a problem updating Tor etc, but since then, when ever I try to open it it just crashes and gives me this windows message. (http://i.imgur.com/ouZMTTh.jpg?1) I've spent hours trying to find away around it (inc USBs).

Any help would be appreciated :)

how is this not a security update while tor 0.2.5.10 contaiuns security fixes and upgrades?

64-bit Tor Browser already exists for 64-bit GNU/Linux, so I assume you're talking about for Windows. Tor Browser going 64-bit isn't going to happen on Windows until Firefox releases 64-bit versions, as Tor Browser is based on Firefox and doesn't have the programming staff to deal with getting 64-bit builds done themselves.

With that said, when you say it is "lagging alot," what do you mean by lagging? Unless you have a lot of tabs open, Tor Browser shouldn't be talking up enough memory for 64-bit to provide a significant benefit. If you're referring to page load time, that's an unfortunate cost of the anonymity that Tor provides and can't be eliminated.

Don;t forget the mac, and I don't mean page load speed, page load speed was never that bad as people claim it to be. What I meant was scrolling down a page (for example) even when I'm only on 1 tab, or minimizing the browser, etc.. it lags it doesn't move smoothly, it seems like it moves step by step, piece by piece taking ALOT of time to do its task like minimizing or scrolling down...

I tried to download the Tor browser 4.0.1 from this website, and it contained a virus and I had to delete it.
Although I downloaded the Tor browser 4.0 from this website and it does not contain any viruses.
Can the Tor project please do something to remove this virus on the Tor browser 4.0.1?

An computer user with even moderate ability doesn't need to be running any of this 'anti-virus' scam junk! It only bogs down your system and make you paranoid!

I've noticed that when using Tor Browser 4.0.0, visiting the JonDoNym website via their ip-check.info diagnostic page no longer works. It hangs and never delivers the diagnostic results page.

Me again.

I installed TBB 4.0.1, and ip-check.info still won't run the diagnostics.

It hangs with a message at the bottom saying "Beginning FTP transaction", then it just sits there. It has run perfectly on all versions before 4.0.0.

When I temporarily enable scripts in NoScript it runs, but I didn't used to have to do that. As a result it lowers the security test score because scripts are enabled.

i have just downloaded the tor browser 4.0.1
i am making this comment using the tor browser 4.0.1
i have feedback for the tor project ,tor browser 4.0.1 is great and works well.
i have trend micro security and when i tried to download the tor browser 4.0.1 from this website it said that the publisher is unknown and that this file could potentially harm my computer, i ignored the message and i just downloaded it anyway

Right -- we've had tickets open for a while to do the platform-specific package signing that each platform expects. But nobody has gotten around to it for years, mostly because none of the developers use any of those platforms. :(

I really hope the next TorBrowser release supports H.264, you can ask Mozilla to backport it, or you can patch it. H.264 will increase TorBrowser's usability significantly, which will increase its user base, and hence the anonymity it provides.

Also, why don't you take advantage of webRTC and make it a Skype alternative?

My understanding is that H.264 is still patented, and the only reason firefox has it is that they've got Cisco building the code for them and they don't actually distribute it (the firefox installer goes and retrieves it from Cisco's servers which removes some of the patent concerns for Mozilla.) Code compiled by a third party is a rather large concern in Tor Browser where it could be used to leak. Yes, it might increase the user base but it isn't worthwhile given the security concerns.

This isn't true for FFv34:"Built-in support for H264 (MP4) on Mac OS X Snow Leopard (10.6) and newer through native APIs" the release notes.
And by releasing v34 firefox is now effectively supporting H264 on all platforms: for mac (v34), windows (since v21), and linux (since v26).

I hope that too, so many websites are giving errors about not playing videos that wouldn't give and would have played nicely if tb supports h264

I thought NoScript was supposed to have been fixed so that you don't have to keep clicking on permissions for every subsequent sub-script.

I also run NoScript on my firefox browser, same version, and it behaves as it always has, where when I grant temporary permissions, I have to click 5-6 more times to do the same for every sub-script.

I downloaded TB 4.0.1and clean installed it [i.e. not over a previous version] but Firefox refuses to open. I deleted it and went back to TB 3.6.6_en-US which is where I am posting from and it works without any problems. Any suggestions as I always try to use the most updated version.

I've never had Trusteer Rapport, plus the "directshow.enabled" setting is now false by default, and I can confirm that this version *still* has problems loading on Windows 7.

Roughly half the time, it works normally. The other half, it will load firefox.exe and tor.exe into memory and that's the end of it -- no browser window ever appears, and I have to manually end both processes and try again. It's utterly random whether it opens or not. It literally may not work, I kill the processes, then try again immediately and it loads normally!!! I can't figure out what causes it to load or not load. I'm also amazed that no one behind Tor has seemingly seen this behavior, while many people have reported it.

I'm using 4.0.1, but it usually takes 2 or 3 attempts to load properly, which is just... bleh.

hello dear TOR guys :)
I don't know! it's because of some of add-on s that I've installed or what?! my 4.1 works fine & opens webpages (right now I'm using it to make comment for you), but when I installed some add-ons, it stopped to work and starts to show the same problem that 4.0 did; acts like have no connection to the internet except it could open the TOR browser (same as 4.1) but just this, nothing more! (TOR browser shows but it cant open not a single page!)
thanks for your efforts guys, we really appreciate it.

First of all, not everyone runs intrusive antiviruses even on Windows; the "spies" are almost entirely third-party tools. This doesn't mean that Windows is safer than other OSes; it almost certainly has backdoors in it, but they have to be accessed. With that said, you can expect that Microsoft only gives those backdoors to governments and corporations it is on good relations with. It might not effect you much, but for users in countries whose governments aren't on good terms with Microsoft, they can expect they're government to have significantly more trouble monitoring them on machines running Windows. Tor isn't only a program for anonymity in the West; that's why they get government funding along with other similar programs.

Secondly, even though other OSes are open source and can have their source code reviewed that doesn't mean they can't have security bugs or even have flaws intentionally coded by agents of certain governmental or corporate organizations. The code base is just to big and complicated to expect even a detailed review to have a good chance of finding them. Heartbleed was a bug in a smaller piece of software that had a greater than normal number of eyes on it and it went unreported for a significant amount of time.

I'm not trying to say Windows is superior; simply that alternatives might be superior to Windows but they're still not perfect. You don't have perfect security on them just like you don't have perfect security on Windows. Perfect security is functionally impossible as long as you're using a computer. It's about maximizing security, and for some use cases where changing Operating Systems is impossible for a variety of reasons Tor Browser can be used to increase security on Windows.

Tor devs have no resource to support windows versions of tor software properly by design. Nobody of them using any of windows and MinGW will never support all new features that need for firefox to work, after mingw fixes old buggy features firefox begins to use new one that working only for MSVC builds. And Mozilla have no MinGW support for real. Look at TBB bugs affected by mingw, lack of feature or bug in implementation of run-time in every case.

hi
I made a comment before on this post (not published yet) but after hours of challenge with my TOR browser, i thought maybe I should make another one. I don't really know what is the "root" of this situation but as a "non-expert" user, I can say these:
1- this problem comes after installing some add-ons and the base TOR browser works fine, even in my old XP window! :)
2- the specific add-on(s) that cause this problem, are not the problem themselves. they are not bad! they're just not working fine with new TOR! that's all! I can say this because the whole add-ons I have on my TOR are as the same as ones I have on my original Firefox and there, they're working beautifully.
3- not sure about this one, but maybe you should check this add-on out. I think (as a non-expert, again) this add-on and its functionality may lead you TOR guys to the root of this problem. https://addons.mozilla.org/en-US/firefox/addon/donottrackplus/?src=user…
thank you again for your endless efforts for us :)

Most Tor user's are criminals.
If you are worried about the NSA spying on you, it means your doing illegal activity.
Remember, if you have nothing to hide, then you should not care about the NSA or any other government agency spying on you.
I don't care about the government spying on me, because I have nothing to hide.
Tor user's must have something to hide.

Total BS!

You may have nothing to hide, but most people have lots to PROTECT.

If YOU have "nothing to hide", then I suggest you remove all the curtains from your windows, remove all the locks from your doors, post a big sign in your front yard listing, in detail, everything you own, and a work schedule so that everyone can know exactly when you are going to be at home, and when you are going to be away.

After all, you have nothing to hide, so you have nothing to worry about, right?

People having access to every detail of your life shouldn't threaten you if you are doing nothing wrong, right?

And we ALL know how totally good and honorable those in government are, right? They would never lie, cheat, or steal, would they? Of course not! They are BETTER than the rest of us, by far.

Surely you can trust your closest neighbors more than the complete strangers in government.

So, why don't you just post all that personal information here first, along with full name, address, and phone number, and prove you aren't a complete hypocrite?

Still missing or not functioning well in Torbrowser (Mac) for three releases now, 3.6.6, 4.0, 4.0.1 :

Tools > Page Info > ...

- The "Media" tab is still missing
- Security tab, "Technical Details" is still keeping empty
- General, "Security information for this page" seems still not to give full security info like 'mother' esr Firefox does.

- "Feeds" tab is also still missing after the 3.6.5 release

The info functionality is a essential extra to monitor security.
Why did you remove this functionality and information?
Why don't you put it back like the way it is in the Firefox esr?

My ISP has blocked me access to the Tor network, how do I continue to use Tor?
To add on that, I downloaded Tor from http://torproject.org/, I'm not sure if that was this website, or wether it was a fake Tor website.

If your ISP has blocked the public Tor relays, you want pluggable transports:
https://www.torproject.org/docs/pluggable-transports

Also, http://torproject.org/ doesn't use https, so it is unclear what site you were actually going to. Your ISP could have pretended to be the site and given you whatever content they wanted. You should go to httpS://www.torproject.org/ to be more sure.

I just downloaded and installed Tor Browser 4.0.1 on Windows 8.1.
But I have problem in verifying it. I followed all the instruction in the link you posted but at the last step instead of getting "Good signature", I get
<" [unknown]>>
Why I get this message? I downloaded the file from the official site. Can you help me by posting some link on how to fix it? Thank you.

@ Arma et al

Tor staff should please keep in mind that many of us reside in areas where any upgrade from XP to other Win levels is not possible due to increased government licensing requirements for users.

Poor financial exchange rates values too prohibit even smugglers from brokering new equipment to ourselves when food, fuel and medicine take priority. Even Win7 is prohibitive and any attempt at downloading a 512Mb Linux/Ubuntu variation - at 16 kbps - soon has the authorities demanding documentations.

Please rethink how many of our activists are now being excluded from international communications as a consequence of incompatibility with your 4.0.0 and 4.0.1 TBB versions.

Thank you for your attention

I hear you.

We're stuck though. Firefox has dropped support for XP, and also dropped support for their older versions that support it. There is no safe browser that we can give you.

Firefox is still supported on XP:

Windows Server 2003 SP1
Windows Vista
Windows 7
Windows 8

https://www.mozilla.org/en-US/firefox/33.0.3/system-requirements/

Also, TBB 4.0.1 is running with no serious problems on XP.
So, I don't understand what you both are talking about.

TBB 4.0.0 was a bust - due to my clumsy fingers!

I've now installed TBB 4.0.1 on my XP, deliberately made the same mistake and crashed. With the re-installation I made sure not to push for a alternative file download path. Problem solved! I also deleted the redundant Tor d/l file from my "My Docs".

To me, TBB 4.0.1 is, except as above, exactly the same as TRR 3.6.6. And what the h--- is "meek". Can't see it anywhere. LOL

Keep up the good job, Tor.

But for those other XP users please allow me to point out that I reformatted and reinstalled XP HE sp3 way back in January in anticipation of MS dropping their XP support system in April.

And I've never looked back!

I plan on upgrading from XP just as soon as a mental-control interface becomes the norm. LOL

Maybe sounds crazy:

I use Vidalia (standalone) to see the circuits.
When my 1st EntryGuard is stressed by deleting circuits my
2nd EntryGuard (or the 3rd) builds one always with 'zwiebeltorolaf' as ExitNode
(the circuit works same as others and the Node in the middle changes).

Signature of TBB is checked.
I changed the EntryGuards and excluded 'zwiebeltorolaf' (ExcludeNodes) in torrc but this doesn't help.

Is this a default behaviour (since TBB 4.0, now 4.0.1) of Tor?

And YES, I'm able to reproduce it.
I can see this every session.

Why is Torbrowser for Mac actually 32 bit instead of 64 bit?

The original Firefox ESR for Mac is already for a long time 64 bit, running without any problems on 32 bit as 64 bit MacIntel-machines as well (minimum os x 10.6 and later).

Both deal with missing page info, but the security tab at least shows up (for me)...media info is completely missing.

"but the security tab at least shows up (for me)"

Yes but its not in function, "Technical Details" stay's empty.

Tor Browser 4.0.1 probably has an DNS leak.
Steps to reproduce on Windows with a enabled firewall (eg. Comodo):
1. Disable system DNS cache.
2. Go to any www site and download any link or file use "Save link as..."
After downloading the file a firewall will report a few UDP request on port 53 to the clearnet.

My DSL service allows upload speeds of more than 300K.

In my Tor relay settings, I have specified 50K for both average and minimum. The Tor bandwidth self-test usualy shows close to that.

So when I click restart Tor I just get the same message. I have downloaded the latest version (I was using 4.0) - but the same error keeps occurring.

When I click to copy the Tor Log it just shows as blank i.e. no info
