Ubuntu – Tor browser not opening


Whenever I start Tor in Ubuntu 13.04, the Vidalia Control Panel opens, loads up and displays a status of "Connected to the Tor network!". However, the tor-infused firefox, does not pop up like it should.

Tor Browser 10 fixes Bug 33906: Fix Tor-Launcher issues for Firefox 75.

Tor Browser (torbrowser-launcher) is available in the default Ubuntu repositories in Ubuntu 16.04 and later. torbrowser-launcher handles downloading the most recent version of Tor Browser Bundle for you, in your language and for your architecture. After installing Tor Browser, it can be launched by searching for tor in the Dash and clicking the Tor Browser icon. The Tor Browser Launcher Settings app is also installed along with Tor Browser.


Unfortunately the Tor Browser developers change their signing key that is used to install Tor Browser at periodic intervals which makes the torbrowser-launcher package from the default Ubuntu repositories not work because it is not as up-to-date as the current version of Tor Browser.

These are the instructions from the official Tor Browser User Manual in case the Ubuntu torbrowser-launcher package hasn't updated the gpg key that is required to install Tor Browser. When I updated the Tor Browser Developers signing key I noticed that the key that I updated will expire in less than one year.

  1. Navigate to the Tor Browser download page.

  2. Download the GNU/Linux .tar.xz file

  3. (Recommended) Verify the file's signature. The steps for verifying the file's signature are shown below.

  4. When the download is complete, extract the archive with the command tar -xf [TB archive] or with the Archive Manager.

  5. Navigate to the newly extracted Tor Browser directory. Right click on start-tor-browser.desktop, open Properties and change the permission to Allow executing file as program by clicking the checkbox. Double-click the icon to start up Tor Browser for the first time.

  6. Alternatively, from inside the Tor Browser directory, you can also start from the command line by running:


How to verify Tor Browser's signature

Fetching the Tor Developers key

The Tor Browser team signs Tor Browser releases. Import the Tor Browser Developers signing key (0xEF6E286DDA85EA2A4BA7DE684E2C6E8793298290):

gpg --auto-key-locate nodefault,wkd --locate-keys torbrowser@torproject.org

This should show you something like:

gpg: key 4E2C6E8793298290: public key "Tor Browser Developers (signing key) <torbrowser@torproject.org>" imported
gpg: Total number processed: 1
gpg:               imported: 1
pub   rsa4096 2014-12-15 [C] [expires: 2020-08-24]
uid           [ unknown] Tor Browser Developers (signing key) <torbrowser@torproject.org>
sub   rsa4096 2018-05-26 [S] [expires: 2020-09-12]

After importing the key, you can save it to a file (identifying it by fingerprint here):

gpg --output ./tor.keyring --export 0xEF6E286DDA85EA2A4BA7DE684E2C6E8793298290

Verifying the signature

To verify the signature of the package you downloaded, you will need to download the corresponding ".asc" signature file as well as the installer file itself, and verify it with a command that asks GnuPG to verify the file that you downloaded.

The example below assumes that you downloaded these two files to your Downloads folder.

gpgv --keyring ./tor.keyring ~/Downloads/tor-browser-linux64-9.0_en-US.tar.xz{.asc,}

The result of the command should produce something like this:

gpgv: Signature made 07/08/19 04:03:49 Pacific Daylight Time
gpgv:                using RSA key EB774491D9FF06E2
gpgv: Good signature from "Tor Browser Developers (signing key) <torbrowser@torproject.org>"
