ok, I disabled unveil by renaming all unveil* files and creating new files that contain only "# disable". the issue persists though. another hint: libmozav* files in /usr/local/lib/tor-browser have the extension .7.0. those in /usr/local/lib/firefox-esr, have the extension 9.0. maybe that's the reason.
