Tor quits unexpectedly at Brave startup

Brave Browser Desktop Support
1

First, I am running Brave 0.23.19
V8 6.7.288.46
rev 178c3fb
Muon 7.1.3
OS Release 15.6.0
Update Channe| Release
OS Architecture x64
OS Platform macOS
Node.js 7.9.0
Brave Sync v1.4.2
libchromiumcontent 67.0.3396.87

I am running Brave on an iMac using OS X 10.11.6.

Whenever I start Brave, I get a message that says ‘tor quit unexpectedly’ with an option to ‘ignore’ or ‘report’. If I select ‘ignore’ Brave seems to open normally. If I select ‘report’, I get the option to send what appears to be a dump to Apple. If I choose to send the report to Apple, Brave still seems to open normally.

I am not a Tor user nor have I done anything with regard to Tor on this Mac…at least that I know of.

I have a screenshot of the message and I have copied the contents of the ‘report’ to an RTF file that I’d be happy to send you if that could be useful…but I haven’t figured out how to attach either file to this message. The contents of the report are as follows, if that is useful.

Any advice would be appreciated…bob

Does this relate to your problem or can you not connect at all? https://github.com/brave/browser-laptop/issues/14623

3

Thanks but it doesn’t seem to be related to what I am seeing. Is there a way to disable this Tor feature in Brave? Brave seems to work fine for me without it.

4

You can just turn it off, shouldn’t interrupt anything for you, since you turned it off, turn the orange switch to grey when you are in a private tab.

5

A screenshot of the Tor message I get at startup is attached. I’ve replied to your message to me. Thanks…b

6

This is the message you get while using a ‘tor tab’ in Brave?

7

This is the message I get when I start Brave. Once I choose to ‘ignore’ the error, Brave runs normally from what I can see. If I try to use a Tor tab, which I don’t normally do, I get the message as noted in the attached, where I would respond to disable Tor.

Does this clarify what I am seeing? …b

Thanks for the report! From the crash dump this looks like a pretty straightforward problem. I’ve filed an issue to track it: https://github.com/brave/tor_build_scripts/issues/18

9

Thanks so much…appreciated…b

10

Just downloaded the latest update to Brave 0.23.31. This issue is resolved. Thanks again…b

11

@BCanuel Just to be clear: 0.23.31 does not fix the bug you reported, but it does delay the symptom — you won’t see the bug until you open a new private tab with Tor. We still need to fix https://github.com/brave/tor_build_scripts/issues/18 in order for private tabs with Tor to work for you.

12

Got it…thanks so much for the clarification. I never use Tor so I’m not expecting to see this issue. Regards…bob
