How to customize torrc in TBB 11?

Hi! I want to add some customized tor configuations in TBB11 by changing tor-browser_en-US/Browser/TorBrowser/Data/Tor/torrc. However, I found that everytime I launched the TBB 11, the torrc file got overwritten and some of the configs (not all of them) were ignored.

Is there other ways to feed in torrc configs?


Any valid torrc options should work unless you write it as a comment, which then will not be preserved whenever you relaunch Tor Browser.

Reading your question, I was reminded of this project one community member recently posted on the mailing list: [ux] Firefox Add-on for torrc functions of Tor Browser


Thank you for your help! I will check the post you provide later.

But for my question, I just double checked and found the issue did exist in TBB 11. In my test, I modify the torrc as

ReachableAddresses *:443, *:9001, *:9030
NumCPUs 60

After I launch TBB11, it becomes

# This file was generated by Tor; if you edit it, comments will not be preserved
# The old torrc file was renamed to torrc.orig.1, and Tor will ignore it

ClientOnionAuthDir xxx
DataDirectory xxx
GeoIPFile xxx
GeoIPv6File xxx
NumCPUs 60

The ReachableAddresses is ignored. Also, a friend of mine said that the Pluggable Transport-related configs would also be ignored.

This does not happen to me in TBB10.
