Comment (by FriendFX):

 After some more research, and finding #29360, I could solve the issue by
 following this comment:
 https://trac.torproject.org/projects/tor/ticket/29360#comment:11

 Initially I tried to create a symlink like so

 {{{
 cd Browser/.config
 ln -s ~/.config/pulse
 }}}

 but that resulted in errors

 {{{
 Failed to create secure directory (.../Browser/.config/pulse): Too many
 levels of symbolic links)

 }}}

 The solution was to use copy instead of symlinking:
 {{{
 cd Browser/.config
 cp -a ~/.config/pulse ./
 }}}

 I hope this practice doesn't cause any security/privacy issues?
