Tor Browser issue

after upgrading to tor browser 9 , my TB failed to start properly just black screen and nothing else

Welcome to Whonix forums and thank you for your question!

Not clear if this can be debugged / fixed.

To re-install Tor Browser with Tor Browser data loss (loosing browser profile, bookmarks, …):

Use Tor Browser Downloader (by Whonix Developers) as per:

Tor Browser Essentials

To debug:

Try to start from command line:

Tor Browser Essentials

Try to start in debugging mode:

Tor Browser Essentials

And post output here.

i am sorry my original login not allow me to post or reply

Using AppArmor?
Whonix version?
Tor Browser version?

If using AppArmor:

sudo journalctl | grep -i denied

It’s probably an issue with apparmor or firejail if you’re using those.

It says it’s being denied access to /dev/dri/ and /dev/shm/org.mozilla.ipc.* but the Tor Browser apparmor profile grants access to both of those.

Did you make any modifications to the profile?

What does running sudo aa-logprof give you?


Output of

dpkg -l | grep torbrowser

ERROR: Values added to a non-existing variable @{HOMEDIRS}: /rw/home/ in tunables/home.d/live-mode

But things working

ii apparmor-profile-torbrowser 3:4.8-1 all AppArmor profile for The Tor Browser Bundle (TBB)
ii tb-default-browser 3:2.2-1 all Configures system to use /usr/bin/torbrowser as default browser

You probably didn’t update the apparmor profile in a while then.

This issue was fixed a while ago. You need to update.

Thanks you so much for kind help , should i update apparmor from tester repo ? or manually update all profiles

You shouldn’t use the testing repos unless you want to test new Whonix features.

Just update everything by running

sudo apt-get-update-plus dist-upgrade

It would be better to use

owner /run/user/[0-9]*/dconf/ rw,
owner /run/user/[0-9]*/dconf/** rw,

instead. It’s much more strict.

Did you upgrade?

I remember some listed there which should be fixed already.
