Brave Crashes Using Private TOR tab after pressing the Enter key



When attempting to use a “New Private Tab with Tor”, the tab opens fine, I type something (anything) in the search bar, e.g. then I press the “Enter” key and the browser closes completely. This only happens with a Tor tab.

Steps to Reproduce

1.Start Brave
2.Open Tor private tab
3.enter anything in address bar and press enter

Actual result:

Brave closes.

Expected result:
I would expect the term I enter would be searched on when I press the enter key

Reproduces how often:

Additional Information


Hey @brianwraith,
Thanks for reaching out to us with this issue - also excellent report! :slight_smile:

While I dig into this issue, you said that after opening a tor private tab and pressing enter in the URL bar to go to a specified address, the browser crashes. Does the browser crash if you use a tor tab without pressing enter? To test:

  • Open Brave
  • Open tor private tab
  • Type an easy to enter URL somewhere other than the URL bar (for example, open notepad and type
  • Cut the URL you typed, right click the URL bar in Brave, select “paste and go”
    Does the browser still close?

Brave Team


Hello @Mattches, following your instructions the browser did not close. I then tried typing in the URL field and pressing enter and it remained stable, opened up an additional TOR tab, typed, pressed enter and still stable.

Closed Brave, opened it again, opened a Tor tab, typed in the URL field, pressed enter and it closed again. I restarted it again, tor tab then typed and it remained open and resolved the address.

I am not typing out every attempt but it seems that it closes most often when typing google in the url field and pressing enter. Other sites seem to resolve.


After looking around it does seem like we have a very similar issue logged already:

While we are working on this, if you can produce verifiable steps to reproduce it would certainly help us track the error down. You can look here for more information on “steps to reproduce (STR)” and how to report a bug. Feel free to copy and paste the template to make filling it out easier and reply here :slight_smile:


The problem you cited doesn’t seem to resemble the problem I am experiencing.

I already used the template in my initial report. I will simply give you the steps again:

  1. Windows 7 professional
  2. Open Brave
  3. Open new private tab with Tor
  4. type “google” in the URL field of the Tor tab.
  5. press enter
  6. Brave closes instantly.


Thanks for the steps, we appreciate that :slight_smile:

We can’t seem to reproduce the bug on our end. We would like to try and get a bit more information surrounding the issue, but in order to do so, we’ll need you to download a git for windows and launch Brave from the terminal and observe the error log (in terminal) when Brave crashes. If you know how to do this already, reply with the error log. If not, don’t worry, its not too complicated. Do the following:

  • Go to and download Git for Windows
  • Install it with default settings - no need to change anything
  • Once downloaded, type “Git Bash” (no quotes) into your windows search bar
  • When the terminal shows up, navigate to the directory in which Brave is stored (if you don’t know how to do this in the terminal, you can find where it is using windows normally and when you get there, right click and copy the path, go back to git, type cd, then right click and paste the path, then hit enter).
    Once there, type start Brave.exe (or whatever you may have named it), then produce the error again. Let us know what is displayed in the terminal and if you need help at any point please don’t hesitate to let us know :slight_smile:


Adding in my two cents, mine only crashes when I try to access blocked sites via my employer’s network. So I can load normal pages but pages which my company has flagged will cause Brave to crash. Did this for testing purposes. My company is using Cisco ScanSafe btw.


Mac, “tor” crashes immediately after Brave start and each time I attempt to open Tor Tab.

@s-kot It sounds like if it’s just the tor process that crashes, and not the whole Brave browser, then your issue is more likely to be: The other issues look more like as noted, which may need more feedback to investigate and debug.


Oh, it’s already there :slight_smile:
I just found a 100% reliable method to crash Brave, OS is Windows-7, Brave version according to about Brave:

Brave: 0.23.31
rev: 3148acef36dba0fce89108638bb27927c4937f90
Muon: 7.1.5
OS Release: 6.1.7600
Update Channel: Release
OS Architecture: x64
OS Platform: Microsoft Windows
Node.js: 7.9.0
Brave Sync: v1.4.2
libchromiumcontent: 67.0.3396.103

How to crash Brave every time:

Nothing is blocked here, but I get “This site cannot be loaded due to a certificate error:” if I type it into a new tab created with Ctrl-T.

Hope this helps :slight_smile: I have to send this off before I try opening in a private tab with Tor without going to the torproject page first, because I already know that this post will be gone after a restart, guess why I know this :stuck_out_tongue: In addition, Brave has (so far) never crashed whatever I did in a normal new tab but I had a few unreproducible crashes with private tabs with Tor. Alas, this is the first time I can provide a recipe to crash it 100% reliable every time. Not sure whether the other tabs are involved or not.

Edit: Now it can’t connect to the Tor network anymore and the task manager shows clearly more Brave-processes than there should be. Time to go for some killing…

Edit 2: All these processes vanished when I closed Brave. It starts 11 processes with 1 window that contains 5 tabs :astonished: OK, next try…

Edit 3: It still doesn’t connect to the Tor network. So no more testing for today.

Edit 4, nearly a day later: Still doesn’t connect to the Tor network. I give up on Tor.


Hmmm… Can’t say that version 0.23.39 is a big improvement in respect to crashes involving private tabs with Tor.

  • “Copy Link Address” from “
  • Open a new private Tab with Tor
  • Insert the copied link into the address field of this tab
  • Hit the Return-key – Brave vanishes immediately.

My OS is still Windows-7. Brave full version:
Brave: 0.23.39
rev: a38be75ccb0f699f507b66c4d44b3b21d1677e25
Muon: 7.1.6
OS Release: 6.1.7600
Update Channel: Release
OS Architecture: x64
OS Platform: Microsoft Windows
Node.js: 7.9.0
Brave Sync: v1.4.2
libchromiumcontent: 67.0.3396.103

Edit: Additional hint: Brave is installed in C:\Users\ (username) \AppData\Local\brave\ - not system-wide! Sorry for not mentioning this earlier.

With version 0.23.31 it crashed the first time of inserting a copied URL, then no more and some manual typing was required to crash it.
With version 0.23.39 it crashed 3 times in a row following my recipe (above in this post), then it doesn’t connect to the Tor network anymore.


Thank you for your input.

I was able to reproduce the issue on Windows 7 machine. We will work hard to solve this issue.

You can track the progress here:
