Tor Browser 7.0a3 is released

by boklm | April 20, 2017

Update (May 8 10:20 UTC): Mozilla released Firefox 52.1.1esr fixing among others a security bug which could lead to a potentially exploitable crash on the Windows platform. By default Tor Browser users are not affected as WebGL is put behind click-to-play placeholders, thanks to NoScript. Nevertheless, we are preparing a release later this week picking this fix up and, in addition to that, a lot of other improvements for our alpha series.

Update (Apr 24 8:36 UTC): Thanks to all for testing this alpha release so far. It turns out there are a number of issues that are affecting a lot of our alpha users. The following list should give an overview and help to avoid duplicate bug reports:

  • Tor Browser is crashing when opening/downloading files that need an external application to handle them. This is bug 21766.
  • Tor Browser is crashing on about:addons with the security slider set to "high" and does not show any preferences on about:preferences ticked. This issue is tracked in bug 21962.
  • The canvas prompt is not shown anymore in Tor Browser. This issue is tracked in bug 21778.
  • There is no sound on Linux systems without PulseAudio anymore. This is bug 1247056. Check this one out for Mozilla's reasoning behind dropping ALSA support.

Tor Browser 7.0a3 is now available from the Tor Browser Project page and also from our distribution directory.

This release features important security updates to Firefox.

This is the first alpha release which is based on Firefox ESR 52. We updated all of our patches that did not get upstreamed yet and made Torbutton and Tor Launcher multiprocess (e10s) compatible. After the first nightly build based on ESR52 went out we already fixed a number of bugs associated with this switch. But more remain, please help!

We hope having e10s and Mozilla's content sandbox enabled will be one of the major new features in the upcoming Tor Browser 7.0 series, both security- and performance-wise. While we are still working on the sandboxing part for Windows, both Linux and macOS have e10s and content sandboxing enabled by default in Tor Browser 7.0a3. There are already a number of bugs related to that on our radar which can be found on our bug tracker and which are tagged with the `tbb-e10s` keyword. If you find more, please report them!

The switch to Firefox ESR 52 raises the system requirements for Tor Browser on Windows and macOS. Computers running Windows and are not SSE2-capable are not supported anymore. On Apple computers with OS X < 10.9 Tor Browser won't run anymore either. Update (Apr 24 8:41 UTC): Only the browser part of Tor Browser is affected by these new constraints. If you are e.g. on Windows and are using the expert bundle or are extracting tor from Tor Browser it should run on any computer it used to run. The same holds for macOS with one exception: tor we ship in Tor Browser won't run on Apple computers with OS X 10.6 anymore either.

We updated our toolchains during the ESR transition as well. In particular we retired the old GCC-based one for our macOS cross-compilation and rely solely on clang/cctools now. As with previous releases building 7.0a3 is fully reproducible on all three supported platforms, even though we needed to deploy a last minute patch for Linux bundles this time.

Apart from switching to the new ESR and dealing with related issues we included a new Tor alpha (0.3.0.5-rc) and updated our NoScript (5.0.2) and HTTPS-Everywhere versions (5.2.14). The Sandboxed Tor Browser for Linux got updated to 0.0.6 making sure it is compatible with Firefox ESR 52.

As in Tor Browser 6.5.2 we provide a fix for Tor Browser crashing on github.com on Windows and for Twitter issues that got reported already a while ago. We update our security slider as well taking newer JIT preferences into account.

A note to Windows users: We signed the .exe files with a new codesigning certificate as the old one is about to expire. If there are issues with that new certificate, e.g. scary warnings showing up after downloading a Tor Browser .exe file and double-clicking on it, please let us know.

You mean when you will be able to use Snowflake? If you have Tor Browser alpha this is available on Linux only for now. The Snowflake folks are working on getting it integrated into macOS and Windows bundles as well.

Indeed it does seem that the effects are pretty noticeable! Youtube is much more smoother than it used to be on earlier version! :)

Is the content process sandbox for Firefox 52 on Windows the same one that is used in Chromium?

Roughly, yes. Mozilla imports Google's code and adapts it to their needs. I am not sure whether the sandbox in Mozilla provides the same protections yet but the codebase is the same.

When I went to about:addons and then "Get Add-ons" and I choosed uBlock to install it, it told me "Firefox blocked this site from attempting to install add-on" or something allong those lines

This doesn't happen with Tor Browser 6.5.2

So, I just tried with a clean 7.0a3 on a Linux machine. I opened about:addons and entered "ublock" in the "Search all add-ons"-checkbox and installed it that way. It worked as expected. Going to a website to test whether it actually does things confirmed that. How can I reproduce your problem?

He talked about "Get Add-ons", not "Search all add-ons"-checkbox.

That does not make a difference for me. Does setting "extensions.logging.enabled" to "true" give you some error messages in the browser console (Ctrl+Shift+J) that explain what is going on? Is that reproducible with a clean new 7.0a3?

FF allows installing addons from AMO & testpilot sites only. Try to install NoScript from its site, and you'll get the same error. Also the behavior of GetAddons is different for every Security Settings level (+ e10s on/off)!

I was able to install uBlock, but all it shows is the button to open the dashboard/settings. I can't see or use anything below enable/disable i/o button e.g. requests blocked, element picker, logger, block elements & media, etc.

Since there is no mention of it I'd assume Thunderbird/IceW with TorBirdie is still not working in the 7.0x platform

Why not? I think on Windows it should work out of the box. On macOs and Linux we currently test unix domain sockets and I guess TorBirdy/Thunderbird need to get taught how to deal with that, yes. But I think it is reasonable to assume that this will be solved until that domain sockets feature reaches the stable channel.

Please clarify your announcement about now requiring SSE2-capable processors : is it for the *browser* component only, or is it applicable to the core Tor proxy (viz, tor.exe on Windows 32 bits) ?

Very crashy on windows. Managed to crash it from the hamburger menu's Customize feature and crashed again when trying to post a comment on this very page. Looks like some very strong improvements otherwise, keep up the great work

Do you have steps to reproduce any of your crashes? If so, please let us know them, so we have a chance to get those issues fixed in the next (alpha) release. Thanks.

Both crashes happened within minutes of a fresh install. I'm happy to go more in-depth, but when the crashes are that easy to experience I ponder the value of reporting when just a few minutes of experimenting with the UI and browsing around some sites such as the tor blog can provoke several. The browser totally freezed when typing a comment in the comment box of this blog, for one. Another crash I experience happened after clicking the hamburger menu, then clicking Customize, then dragging some icons to and from (and on either side of) the address bar. IIRC the crash happened after dragging the search bar off and placing it off the browser (to the dock of unused items just above the cut/copy/paste entries). I experienced another crash when opening about:config, and another crash when changing my download folder location from the Options screen. Also, many UI elements are missing throughout the browser (such as the little dots that indicate a selected option from the General section of the Options menu where the Downloads folder may be changed). Sorry if all of this is brief. I don't get any crashes in 7.0a2 or in the new 6.5.2. I greatly anticipate being able to use the new e10s features and hope a lot of this can be ironed out for 7.0a4. Platform is Win 10 64bit with creators update.

Thanks. We'll look into it and get back to you in case we have further questions. Special thanks for testing this on Windows as this is usually the platform that gets tested not so much by the developers yet we have the most users on it.

Okay, I tried quite a bit on my Windows 7 machine but I could not reproduce any of those crashes you are seeing. Could you give me some steps to reproduce at least some of them? Are they happening with a clean, new Tor Browser 7.0a3 (i.e. one freshly downloaded and without any modifications)?

There are so many changes in FPI, so could you change Torbutton's INFOs about violations of it into warnings about it?

April 21, 2017

In reply to gk

Everything that violates FPI and goes through catch-all or noname circuits should be logged at higher logging level of Torbutton (now it's too noisy by INFO messages).

I see. There is a bunch of stuff that we'll need to disable for the next alpha I hope or latest for the stable release. Thus, I think this will get much better. Let's wait for that until we think about changing the log level.

Hi Yawning
Yes,
It looks really bad at the moment, from the multiple bug reports and even articles on the net it seems that they are very firm on to this track now,

they do not want to listen to the users that ,without warning, lost their websound, the solution they tell is add pulseaudio and make your system bad or "then you have to switch distro" , many many of the users in this situation can or will not add on the pulseaudio-layers now,

Therefore users will probably look for another browser instead? But as far as I know noscript and more is only for firefox, so that is not an option for some users that still care not to run all kind of not so nice scripts by default.

Same on Gentoo after installing Pulseaudio. No more sound. Pulseaudio doesn't detect my Xonar card. All it shows is the dummy-sink.

Hmm

This is probably not the optimal way to go now for security, but if mozillafox really have decided that it must use a "man in the middle", is there some other easy way to use or make a small and more secure middle-ware, that now ONLY redirects firefox audio to use alsa as normal,

and maybe even without using JACK, ..if JACK is the normal system setup..
So if our program just pretend to be pulseaudio, what happens? can we then get sound back again without having all the bloaty scary downsides with pulseaudios insecurity and the other damages to the sound quality/latency problems in our systems?

(It seems so, as kxstudio have some option to run both JACK and Pulse in parallel (?) as I understand the solutions it will always be another program layer on top of alsa and not direct to alsa as usual, But why use pulseaudio at all then? Only because of the browser.. )

so if possible (maybe it have been done already by someone?), would this "minipulse" middleman be the second best alternative after having a future "pulsefree" Firefox version?

Hi,
sorry I dont know much about that problem with firefox,
is that "worse" than a possible memory and audio-snooping trough pulseaudio?

But the point was more from a security perspective, as I see it.
How to get rid of as much unknown software in the middle as possible.
Not to install truckloads more of them :-)

Same issues from 6.5a2 returned, which dcf created ticket #19837 for. dcf said it was about experimenting with #19273.

Thanks for the report. How do I reproduce your problem? I tested with a 7.0a3 on Windows and Linux following the links dcf mentioned in the description of #19837. Both loaded fine for me. Does this happen with a clean and freshly downloaded 7.0a3?

I didn't know when comments close so I guess I rushed; I haven't really had the chance to play around with this release yet. I'll try a fresh install in a few days. I used the same wired router to send in our taxes from another machine, and when I connected this one again there were strange requests through ports, Ru malware that kept respawning in different places, drivers & registry keys screwed with, firewall & security software disabled, MBAM not working.It's been a headache that I've been trying to sort out for over a week now. I've had to run a number of system restores and update TB in addition to other programs so I'll just assume for now that that's the likely cause of my issues. I'll let you know if it's still happening after a clean install.Thanks for taking the time to respond.

Did Cl0udflare change how it handles Tor recently? In the previous alpha release, Cl0udflare-hosted sites seemed to work flawlessly and I rarely had to solve captchas. However, over the past month or two, I've had to contend with the dreaded "Attention Required" page on nearly every site again. It seems like the issues w/ Cl0udflare have gotten worse than they were last year.

I'm seeing two Tor Browser processes simultaneously in Win Task Manager. Only a single application running, but two firefox.exe *32.[Is this how e10s would appear & would multiprocessing FF be a likely reason why some add-ons are not working as expected?]The second process appears after Tor connects to the network, as the browser is loading, just prior to About:tor displaying as the home page. Right after this, the 2nd process disappears, but comes back the moment I do anything outside of the home page, About:*, or options; if I search, load a locally stored file, or anything else, the 2nd firefox.exe *32 process appears.If I go back to the previous page i.e. the home page, I get a 'Problem Loading Page' tab, & a warning message stating 'The address isn't valid...' If I reload the About:tor page after closing the other tabs then the 2nd firefox.exe * 32 disappears again.[Again, just wondering if this is how Electrolysis child processes appear & if the compatibility of some FF add-ons would be affected.]

Yes, I think you describe the e10s behavior. I am not sure about your add-on issues, though, because Tor Browser, as Firefox is supposed to do, should fall back to e10s being disabled once it encounters an extension that is not compatible with it. But maybe those extensions you have are falling through the cracks? How can I reproduce your problems?

Yes, the issue with going back to about:tor is known: see: https://trac.torproject.org/projects/tor/ticket/21948.

OK, well the minor issues seemed to be identical to what I experienced in 6.5a2; see: comment tree from Reply #1199 on the 6.5a2 blog post where dcf created ticket #19837.Around a week ago I think my browser's support page said that multiprocess windows were disabled, probably because the add-ons were incompatible with e10s like you described. They're enabled now, and I assume have been since I removed the add-ons last week. They were DTA AntiContainer & Flashgot.Just to be clear, TB seems to be working fine and I only experienced the issue with those particular add-ons installed. I guess I'll just have to wait for the developers of those extensions to re-write them to be compatible with the WebExtensions API.Thank you for your time, gk.

NoScript seems to have slown down Tor Browser very often. When this happens, the slowdown is generally noticeable.

Select is not drag'n'drop, or you are saying Firefox tries to do something in either case?

If you selecting by clicking your mouse, nothing happens. But if you press the left button and move your mouse, then that message appears after releasing the button. This happens on Windows with e10s only.

I know it is not officially recommended to install extra Addons or modify the browser from its original state. But if you do install extra Addons, it extremely slows down 7.0a3. Startup takes like 10 seconds more and during use the browser freezes sometimes for many seconds.

How to recreate the problem:
- Install an Addon for example: uBlock Origin or uMatrix
- You will experience the symptoms during installation and after restarting the browser
-> Browser freezes, Startup takes abnormaly long

Both Windows and Linux, same issue on different PCs and also in a virtual machine
So should not be related to OS or hardware. Also original Firefox 52ESR does NOT have this issue.

Weird. I just tested it on my Windows 7 testing machine and I don't see any differences after installing ublock origin. If you have error messages that might be relevant I'd like to see them. Also, does this happen with a clean, new 7.0a3?

In regular Firefox you can drag a link from the url bar to the desk top. Please turn this on in Tor-browser
